NOTE An  operating  procedure,  condition  and  so  forth,  to  which  special attention should be paid. GENERAL SAFETY PRECAUTIONS   During  transmission,  high  RF  voltages  may  appear  at  the  RF connectors of the transceiver, antenna tuner (ATU), the antenna cable, and on the antenna itself.  Avoid touching the antenna and the RF connectors of a radio set while it operates. Make sure the antenna is not located near high-voltage lines. Operating  and  maintenance  personnel  must  be  familiar  with  the applicable  safety  requirements  and  regulations  before  attempting  to install or operate the radio set.
OM-E 2072-09689-00 ii SAFETY SUMMARY   The  following  are  general  safety  precautions  that  are  not  related  to  any  specific  procedures  and therefore  do  not  appear  elsewhere  in  this  publication.  These  are  recommended  precautions  that personnel must understand and apply during various phases of operation and maintenance.    KEEP  AWAY  FROM  LIVE  CIRCUITS.  Operating  personnel  must  at  all  times  observe  all  safety regulations.  Do  not  replace  components  or  make  adjustments  inside  the  equipment  with  the  high voltage  supply  turned  on.  Under  certain  conditions,  dangerous  potentials  may  exist  even  when  the power  control  is  in  the  OFF  position,  due  to  charges  retained  by  capacitors.  To  avoid  casualties, always remove power and discharge and ground a circuit before touching it.   DO NOT SERVICE OR ADJUST ALONE. Under no circumstances should any person reach into the equipment enclosure for the purpose of servicing or adjusting the equipment except in the presence of someone who is capable of rendering aid.   RESUSCITATION.  Personnel  working  with  or  near  high  voltages  should  be  familiar  with  modern methods of resuscitation.   USE  SAFETY  APPROVED  EQUIPMENT.  When  cleaners  and  primers  are  being  applied,  approved explosion-proof lights, blowers, and other equipment shall be used. Insure that firefighting equipment is readily available and in working order.   GIVE  CLEANERS  SPECIAL  CARE.  Keep  cleaners  in  special  polyethylene  bottles  or  in  safety cans and in minimum quantities. Discard soiled cleaning cloths into safety cans.

OVERVIEW OF MICOM-Z CAPABILITIES Micom-Z  is  a  state-of-art  family  of  adaptive  HF/SSB  radio  sets  designed  to  meet  the  demanding requirements  of  the  operational  environment.  Using  advanced  digital  signal  processing  (DSP) techniques, Micom-Z offers reliable long-range communication for voice, data, and telegraphy (CW) using  upper  sideband  (USB),  lower  sideband  (LSB),  amplitude  modulation  equivalent  (AME),  and pilot modes of operation. Micom-Z  radio  sets  provide  a  complete  solution  to  traditional  HF  communication  problems  while allowing  user-friendly,  easy  operation  even  for  unskilled  users.  Micom-Z  radio  sets  have  been specifically designed to satisfy all the needs of short, medium and long range communication in the crowded HF band.  The main characteristics of the Micom-Z family are described below: • Micom-Z transceivers  are offered in two  flexible configurations: dash-mount and  trunk-mount, designed to fit both fixed and mobile installations. To simplify installation, the transceivers can also provide power through the RF cable to a compatible ATU. • User-Friendly Operation. Designed to render its cutting-edge features usable by unskilled users, the Micom-Z has an intelligent, state-of-the-art, menu-driven man-machine interface (MMI) that is easy to  master, and intuitive to  use. The MMI is based  on a large digital front-panel display with four soft keys, and a standard 16-key keypad; the only additional front-panel control is the radio ON/OFF switch.
OM-E 2072-09689-00 1-2 The MMI enables the operator to perform any desired action easily and efficiently, for example, select  the  desired  operating  mode,  define  or  modify  the  parameters  to  be  used  on  each  preset channel, etc. Many improvements based on user feedback have been incorporated in the MMI, as a part of an ongoing evaluation program. In addition, Micom-Z radio sets enable PC control and programming, via an RS-232 interface. • Robust, Reliable Link Establishment. Micom-Z radio sets support Automatic Link Establishment (ALE) per MIL-STD-188-141B (the required software is supplied embedded as a standard), ALE operation is very simple, and can be easily used even by unskilled operators. In addition, Micom-Z also supports CCIR 493 SelCal (selective calling) with 4-digit and 6-digit addressing per UN-WGET Interoperability Agreement, and beacon calls.  Both  ALE  and  CCIR 493  SelCal  are  interoperable  with  all  the  major  suppliers  supporting the standards. When operating in the ALE or CCIR modes, Micom-Z provide an over-the-air remote disable function: an authorized radio set can transmit a command to a radio which has been lost or stolen to disable all the radio programmable parameters. • Internal GPS Receiver. The Micom-Z can be ordered with an optional integral Global Positioning System (GPS) receiver. In addition to presenting the GPS information on the  display, the ALE AMD or the CCIR 493 Recall GPS call messaging platforms can be used to enable any station to generate a request for GPS location from any other station in the network. The GPS receiver uses a compact, light-weight patch antenna with magnetic mount. • High  Reliability  and  Cost-Effective  Logistics.  The  modular,  3-board  design  of  the  Micom-Z family, with its high MTBF and low MTTR, offers outstanding reliability in field conditions and cost-effective logistic support. A  comprehensive  multilevel  built-in  test  (BIT)  subsystem  helps  the  user  to  identify  faulty modules in the field, and ensures complete functional testing after module replacement. The BIT also  provides valuable  information  to higher echelon  maintenance personnel,  without  requiring module-level test equipment. The Micom-Z family is based on a common transceiver, available in two mounting versions: • Dash-mount  version  –  a  transceiver  with built-in  front  panel,  for  fixed  and  mobile applications.  • Trunk-mount  version  –  a  transceiver with  a separate  control  box  that  is  similar  to  the dash-mount  front  panel  but  requires  an external speaker, saves valuable cabin space in mobile use. NOTE The  audio  accessories  are  for illustration  purposes  only,  and  may vary in accordance with preferences.

OM-E 2072-09689-00 1-4 1-3.2  Micom-Z Transceiver  The  Micom-Z  transceiver  is  a  complete  HF/SSB  receiver-transmitter  capable  of  receiving  and transmitting  voice,  data,  and  continuous-wave  (CW)  telegraphy  using  upper-sideband  (USB), lower-sideband (LSB), AME and pilot carrier modulation. High selectivity and a wide dynamic range ensure clear, undisturbed signal reception.  The  transmit  power  can be  selected  by the operator  for  optimum transmission  performance (125  W PEP  for  maximum  range;  100  W,  60  W  or  25  W  to  reduce  interference  to  nearby  stations,  and decrease power dissipation).  The  transmitter  includes  thermal  protection.  If,  for  any  reason,  the  transmitter  internal  temperature exceeds the maximum permitted temperature, the output power is automatically reduced to avoid any fault due to excessive heat. Antenna mismatch protection is also included: if the antenna VSWR is too high, the transmit power will also be automatically reduced to avoid damage. The  transceiver  nominal  output  impedance  is  50  Ω,  and  therefore  it  can  be  directly  connected  to broadband  antennas  (dipoles,  traveling  wave  antennas,  delta  and  semi-delta  antennas).  For  mobile service using whip antennas, an external antenna tuning unit (ATU) is necessary. Suitable ATUs are available on order.  Micom-Z  utilizes  digital  signal  processing  for  implementing  most  of  the  receiver  functions,  e.g., demodulation,  narrow  band  filtering,  automatic  gain  control,  tunable  notch  filter,  squelch,  etc.  The digital syllabic (speech identifier) squelch is activated whenever speech is identified, thus opening the audio path. However, if speech is not received, the audio path is muted, thus preventing background noise from disturbing the operator. In addition, Micom-Z uses ClearCom, a voice communication denoising algorithm that uses advanced digital  signal  processing  to  remove  background  noise  and  dramatically  enhance  the  received  voice clarity and intelligibility. This means that you can receive clear voice even with weak signals. Since all the processing takes place within the receiving Micom-Z, ClearCom enhances any voice transmission irrespective of the type of far radio set.  Moreover, ClearCom operates only on voice traffic, therefore it can be used even when using ALE or CCIR automatic link establishment protocols, and does not interfere in any way with data or vocoder transmissions.  Therefore,  you  should  enable  ClearCom  whenever  the  reception  is  weak:  when communication conditions are good, ClearCom is not needed and will not make any difference. NOTE The  ClearCom  feature  replaces  the  noise  blanking  feature,  which  is effective only for reducing engine noises. Micom-Z internal GPS  receiver (optional) is a  standard L1-band C/A SPS receiver that  can provide navigation and time-of-day data. The minimum number of satellites that must be received is four, but the receiver can simultaneously receive and process a larger number of satellites, thereby improving the positioning accuracy. When using the ALE or CCIR mode, the positioning data can be sent, upon request, to other radio sets.  The  optional  GPS  receiver  is  supplied  with  an  omnidirectional  GPS  antenna  with  magnetic  mount, which can be located at up to 5 meters (15 feet) from Micom-Z. Two  dedicated  connectors  located  on  the rear panel provide  a  connection  point for connecting  data equipment, and other user’s equipment. The transceiver is powered from 13.8 VDC (nominal) (negative pole grounded). The transceiver can also provide DC power to a compatible ATU, through the RF cable.

OM-E 2072-09689-00 2-4 2-3.  FAMILIARIZATION WITH MICOM-Z OPERATING PROCEDURES  This section provides general procedures that will help you start using your radio and get the most of its advanced features. Most of the activities that can be performed by you (selection of operating mode, programming, testing, etc.)  are done using the keypad together with the navigation and  function keys, and the front panel display. To  simplify  operation,  Micom-Z  function  keys  operate  as  soft  keys  and  therefore  they  permit  you control the radio simply and efficiently, using a menu-driven mode that guides you and helps you make the required selections. “Menu-driven” simply means that whenever you must  select a  parameter, an operating mode, etc., you select it from a list of allowed values displayed on the front panel display, thereby reducing the chance of error: • To make a selection, you use navigation keys to reach the desired parameter value or action, and then confirm the selection by pressing the ENTER   key. • To go back to previous options, or cancel the current selection or action, press the ESC EscP key. 2-3.1  Display Functions  2-3.1.1  Display Organization CH   1F   2,000.00BAND SQ12453 No.   Designation   Description  1  Mode Indicator  Indicates the current working mode (e.g., channel, frequency, ALE, etc.) or the action being performed (e.g., programming, testing, etc.) 2  Work Area  Displays information on the current working mode, the main operating parameters, etc. It also includes icons that identify the active options, and status 3  Level Indicator   In the transmit mode, displays the relative transmit power. In the receive mode, displays the relative received signal strength 4  Tx Bar  Appears when the radio is transmitting 5  Options Display Bar  Displays a list of options you can select, by pressing the corresponding function key, in the current working mode  2-3.1.2  RF Level Indications  Indication   Meaning Strong received signalWeak received signal Received RF signal strength indication, displayed when the radio is in the receive mode. The number of bars provides a relative indication, which may fluctuate as a result of fading, etc. Full transmit powerRelative transmit power Low transmit power Reflected power  Transmit bar, appears when the radio is switched to the transmit mode (for example, when the PTT is pressed). Its length indicates the maximum radio transmit power in the selected mode (MAX, HIGH, MED or LO). The number of bars indicates the instantaneous relative transmit output power, and therefore it fluctuates as a result of modulation. The relative reflected power is indicated by the base line: its length indicates the fraction of power reflected because of antenna VSWR (the length should be small relative to the total height of the transmit bar, which is proportional to the forward power)
OM-E 2072-09689-00 2-5 2-3.1.3  Icons Micom-Z displays icons in two areas: to the right of the channel number, and in the area just above the options display bar (at the left-hand side). Icon  Description  LSB mode  USB mode  Squelch enabled  ClearCom function enabled  Notch filter enabled  Indicates that a special-purpose filter (any filter except the 2.7 kHz filter) is in use  Clarifier enabled  ALE or CCIR stack stores messages   AGC mode set to OFF or FAST  Monitoring enabled  2-3.1.4  Message Attached Alert When  a  message  is  attached  to  the  received  call  (an  option  available  for ALE  calls  even  if  you  are  using  the  Channel  mode,  and  for  the  CCIR mode), an  exclamation sign ! appears  to the left  of the originating station name.  You can view the message contents after you accept the call. FROM!1002 2-3.2  Using the Keypad Each key is imprinted with a numeral and several letters. These characters are accessed in clockwise order, as follows: • A single key press enters the numeral or symbol • Two consecutive key presses enter the first letter • Three consecutive key presses enter the second letter • Four consecutive key presses enter the third letter • Five consecutive key presses enter the fourth letter • To enter a blank space, press 0 twice. 1*DMENUALMGPSEscEFABC2JKL5TUV8NOM6WXYZ930#GHI4PPQS7R
OM-E 2072-09689-00 2-6 When entering frequencies, use the * key as a decimal point, if needed. In the ALE mode, the * key is also used to enter a wild-card character (? or @). To enter the ampersand @ symbol, press the # key twice. Example: To enter a number in a field, or edit (change) the number, you type the desired digits on the keypad. Example:  To  enter  an  alphanumeric  string  in  a  field,  or  edit  a  string,  you  type  the  desired alphanumeric  character  by  pressing  the  appropriate  key  several  times  in  sequence.  For  example,  to enter “MIKE 01”: Press NOM6 twice (for the letter M). Press GHI4 four times (for the letter I). Press JKL5 three times (for the letter K). Press DEF3 three times (for the letter E). Press 0 twice (for the blank space). Press 0 once (for the numeral 0). Press 1 once (for the numeral 1). 2-3.3  Function Keys The function keys F1, F2, F3, and F4, appearing under the display, are soft keys used to select options or actions which depend on the current radio mode. The current function of each key is shown in the options area of the display, above the key. For  example, on the BITE screen you can press F1 to start the full BIT test. If a  certain function key is not used, no label appears above the key (see for example F4), and pressing that key has no effect. BITECHANFULL L.

You cannot use the keypad to enter a value for such parameters. 2-3.7  Toggle Mode When the function being set can only be toggled on or off, one function key will be marked YES and another NO. To expedite turning on and off often-used functions (for example, turn the squelch on or off) only one key is  used.  In this  case, just  press the  key assigned to  the  function to be toggled:  the  new  state is shown for a few seconds, and then disappears as it takes effect immediately. 2-3.8  Alphanumeric Edit Mode When  you  need  to  enter  an  alphanumeric  string  in  a  field,  or  edit  a  string,  you  select  each  desired alphanumeric character on the keypad as explained above. A blinking cursor _ indicates the location being edited. In addition, the following edit function keys are available: SAVE   Saves editing changes (equivalent to pressing the ENTER key). < − −< − −< − −< − −  − − >− − >− − >− − > Used to  move the  cursor backwards and  forwards. When you reach either end, the corresponding key disappears. CLR   Pressing this key momentarily erases the digit/letter at which the cursor is presently located, and shifts the entire field one place to the left.  Pressing this key continuously clears the entire field. 2-3.9  Numeric Edit Mode When you need  to enter a number  in a field, or  edit the  number, you type the  desired digits  on the keypad. A blinking cursor _ indicates the location being edited. In addition, the following edit function keys are available: BACK  Erases the last digit. CLR   Erases all newly entered digits and restores the original value. 2-3.9.1  View Mode When  the  string  to  be  displayed  is  longer  than  the  number  of  characters  that  fit  in  one  line  (for instance, with long addresses or messages), the view mode enables scrolling to the rest of the string. The view mode is indicated by the symbol <<<<    −−−−    >>>> next to one of the function keys. When you press < − >< − >< − >< − >, the key functions change: HOME  Scrolls to display the first character of the string. < − −< − −< − −< − −  −−−− −  −  −  − > > > >  Scroll  one  character  to  the  left  or  right,  respectively.  If  you  press  either  key continuously, the scrolling continues at a rate of four characters per second. END   Scrolls to display the last character of the string.

Menu item  ... and its purpose CHAN  Channel  mode:  the  radio  uses  a  set  of  preset  parameters.  Up  to  200  sets  of parameters can be defined and stored in the Micom-Z, where each set is assigned a channel  number  (1  to  200).  You  can  use  Figure   2-2  to  find  details  on  the selections available on the CHAN menu.  FREQ  Frequency mode: you can select manually the frequency (free tune mode) and the other  parameters  to  be  used.  You  can  use  Figure   2-3  to  find  details  on  the selections available on the FREQ menu. ALE  ALE mode: when you want to call other radio, the radio automatically sets up a link on the best free frequency that can be found. You can also call specific radio sets,  a  group  of  radio,  or  broadcast  to  all  the  radio  sets.  The  sets  of  parameters needed for this operation mode are stored under net numbers (1 to 20), the radio sets are identified by addresses stored by the radio in a directory supporting up to 100 addresses. SCAN  SCAN mode: when neither the ALE, nor the CCIR mode, is used, you can define a  set  of  channels  to  be  scanned  before  starting  a  call.  The  scan  parameters  are always  loaded  by  the  MRC  together  with  the  other  operational  parameters,  and cannot be changed using the Micom-Z panel. CCIR  CCIR mode: mode that supports functions similar to ALE, except that it  uses a different addressing scheme. BIT  BIT mode: lets you check that the Micom-Z is OK. LOCK  Lock  the  radio  to  prevent  unauthorized  use.  To  lock  and  unlock,  you  enter  a password. PROG  Programming mode: lets you program (select and store) the required parameters. Refer to Chapter 4 for details on the selections available on the PROG menu. PSW  Used to change the password.

For  instance,  the  following  represents  a  sequence  of  steps  that  involves  five  key pressings: MENU > MORE > PROG > RAD > CHAN.
OM-E 2072-09689-00 2-11 2-5.  GETTING STARTED This section provides basic operating instructions: it covers issues such as turning the radio on and off, receiving and transmitting, selecting a channel or a frequency, etc. NOTES •  The information needed to use Micom-Z in the ALE mode appears in para.  2-12. •  The  information  needed  to  use  Micom-Z  in  the  CCIR  mode appears in para.  2-13. •  The information needed to use the Micom-Z GPS receiver appears in para.  2-9. You  can  use  these  instructions  to  start  using  your  Micom-Z  radio.  To  become  familiar  with  all  the radio  capabilities and features, refer  to the following sections.  In  most  cases,  the  radio  reaches  you after  being  configured  for  use  in  your  radio  net.  However,  if  you  need  to  make  changes,  refer  to Chapter 4.  2-5.1  Turning the Radio On and Off To turn the radio on:  1. Press the ON/OFF button.                  2. The display turns on and shows SELF TEST for a few seconds.  SELF TEST NOTE If the display is too dim, adjust its brightness using MENU > MORE > DIM.  3. If  the  self-test  procedure  is  successfully  completed,  the  radio automatically  resumes  operation  in  the  last  used  mode  (CHAN, FREQ, ALE, CCIR, or SCAN), and volume.

NOTE If  automatic  dimming  is  enabled  (DIM  is  YES),  the  display may turn off after a few seconds of inactivity. To cancel this feature,  use  MENU  >  MORE  >  PROG  >  RAD  >  PRMT  > DIM to select NO for DIM.  If a  problem is detected during  self-test, the  display shows  ERR and  a  code number, followed by  a concise  description  of  the  error  (if  the  description  does  not  fit  in  one  row,  its  parts  alternate  in  the display). If the detected problem does not prevent using the radio, press EXIT to cancel the display and continue. To turn the radio off: Press the   button again. The display turns blank.
OM-E 2072-09689-00 2-12 2-5.2  Transmitting and Receiving NOTES •  When transmitting, the  RF output of  the radio must be connected to an antenna installed as explained in the Installation chapter (for maintenance,  you  may  also  connect  to  a  dummy  load  of  suitable power rating). Do not attempt to transmit when the antenna is not connected,  or  when  the  antenna  or  any  cable  leading  to  it  is physically damaged. •  If the antenna system is equipped with an automatic antenna tuner and  the  tuner  is  enabled,  the  radio  will  automatically  tune  the antenna  tuner.  In  the  Channel  mode,  pressing  the  ENTER  key automatically retunes the antenna.  To transmit a voice message:  Press and hold down the Push-to-Talk (PTT) button of the microphone, and speak slowly and clearly after the channel is clear.  You should hear a sidetone, which verifies that your radio transmits normally. The display changes to show the TX bar, together with indications of forward and reflected power.  During normal speech, these indications fluctuate  in accordance  with your voice. Tx BarForward Power Reflected Power  To receive calls: When the radio identifies a call addressed to it, it sounds a beep and if it is a voice message – you start hearing it in the speaker. The display shows the name of the calling station (blinking) and the call type. The display  now  shows  the  RX  indication,  which  is  proportional  to  the received signal strength.  Strong received signalWeak received signal 2-5.3  Radio Filter Bandwidth and Service Type The radio filter bandwidth must be selected in accordance with the type of signal to be transmitted and received. For the transmit mode,  the  type of signal is  identified by detecting  the active PTT  signal, which is one of the following: • MIC PTT – PTT from the microphone connected to the front panel connector; transmits your voice. • Voice  PTT  –  PTT  from  an  accessory  connected  to  the  radio  set  through  its  rear  panel ACCESSORY  connector;  it  causes  the  radio  to  transmit  the  voice  signal  provided  by  the accessory device. • Data PTT – PTT from a data device, for example, a modem, connected to the radio set through its  rear  panel  ACCESSORY  connector;  it  causes  the  radio  to  switch  to  the  data  mode  and transmit the modem signal. • CW  PTT  –  PTT  from  a  Morse  key  connected  to  the  radio  set  through  its  rear  panel ACCESSORY connector; it causes the radio to switch to the CW (Morse) transmission mode. The radio operating mode is automatically adapted for best performance with the signal expected for the detected PTT type. A  default filter  bandwidth can  be configured for each  channel using  MENU  > MORE > PROG > RAD > CHAN  (if  no particular  filter is set for  the  current channel,  the radio retains  the previously used filter). When a new type of call is received or sent, the bandwidth filter changes automatically, depending on the PTT  source (voice, data  or  CW), and the  programmed  bandwidth  for the channel being used.

OM-E 2072-09689-00 2-23 2-9.  USING THE GPS RECEIVER (OPTIONAL)  2-9.1  Overview of GPS Receiver Functions  The GPS receiver is an integral part of the Micom-Z transceiver, and can be used whenever the GPS antenna supplied together with the Micom-Z transceiver is properly connected and installed.  The  GPS  receiver  provides  accurate  time  and  navigation  data.  The  navigation  data  includes  the geographical coordinates (position data) and the altitude. When the  Micom-Z  transceiver is moving, you can also see the speed and direction (heading). The format of the navigation data can be selected in accordance with your needs:  • LLA format: Latitude, longitude and altitude (LLA). The latitude and longitude are displayed in degrees,  with  a  precision  of  hundredths  of  arc  minutes  (1/100  min);  the  altitude  is  reported  in meters, relative to the mean sea level (MSL).  Velocity is reported as the change in the East, North, and Up coordinates, presented in meter/sec with a precision of 0.001 m/sec. • ECEF  format:    Earth-Centered,  Earth-Fixed  format  for  position  and  velocity.  Provides  your position  and  velocity  in  a  Cartesian  (X,  Y,  Z)  coordinate  frame  with  its  center  at  the  Earth's center, the Z-axis through the North Pole, and the X-axis through 0 degrees longitude, 0 degrees latitude. The position is reported in meters. Velocity  for  each  axis  (that  is,  is  the  change  in  the  X,  Y  and  Z  coordinate)  is  displayed  in meter/sec, with a precision up to 0.001 m/sec. The time is always presented on basis of the UTC (Universal Time Coordinated).  The information collected by the GPS receiver can be displayed on the Micom-Z display when using the CH and FREQ modes. In the ALE and CCIR modes, the position data can be reported by means of AMD  messages;  it  can  also  be  automatically  reported  in  response  to  position  queries  (also  sent  by AMD messages). 2-9.2  How to Get the Best Results from your Micom-Z GPS Receiver  The  GPS  receiver  extracts  the  information  it  needs  by  analyzing  the  signals  received  from  GPS satellites.  These  satellite  periodically  transmit  navigation  messages,  where  the  transmission  of  each complete message requires almost 15 minutes. To calculate all the data your GPS receiver is capable of providing, it must receive and decode navigation messages from at least 4 GPS satellites (the GPS receiver can use as many as 8 satellites to improve accuracy).  Therefore,  after  turning  a  GPS  receiver  on  for  the  first  time  after  a  long  period  of  inactivity,  it  is essential to let  the GPS receiver  operate continuously for  at least 15  minutes, to  enable it  to collect updated  almanac  data.  After  this  initial  15-minute  interval,  a  GPS  receiver  can  relatively  rapidly acquire the satellites and calculate its position; thereafter, a GPS receiver must remain on only for a few minutes in order to be able to provide navigation data.  The internal GPS receiver is always powered when the transceiver is turned on. Therefore, if the GPS antenna is connected, the GPS receiver can start the acquisition process as soon as the transceiver is turned on, and can then track the satellites continuously.  Turning the Micom-Z transceiver off  will force the GPS receiver to reacquire the satellites. 2-9.3  Operating the GPS Receiver  2-9.3.1  GPS Menu The  GPS menu  is  displayed by selecting the  GPS item on  the  FREQ or CH menu.  The  GPS  menu structure is shown in Figure  2-4.

GPS Menu The menu structure depends on the display format, ECEF or LLA, selected by the FMT item. You can also press the UP or DOWN panel key to toggle the display format. a. The items displayed on the GPS menu when using the LLA format are as follows: FULL  Alternating display of the absolute velocity (VEL) in the horizontal plane, and its direction relative to the North (azimuth – AZIMTH). VERT  Alternating display of altitude and up/down velocity. DHOR  Alternating display of North/South and East/West velocities. HOR  Alternating display of latitude and longitude. TIME  Display the time-of-day obtained from the GPS receiver. DEV  Used to check that the GPS receiver is operating.  FMT  Toggle the display format (to ECEF).  b. The items displayed on the GPS menu when using the ECEF format are as follows: X  Display the X coordinate. Y  Display the Y coordinate. Z  Display the Z coordinate (altitude). DX  Display the velocity along the X axis. DY  Display the velocity along the Y axis. DZ  Display the velocity along the Z axis. TIME  Display the time-of-day obtained from the GPS receiver. FULL  Alternating display of the absolute velocity (VEL), and its direction relative to the North (azimuth – AZIMTH). DEV  Used to check that the GPS receiver is operating.  FMT  Toggle the display format (to LLA).
OM-E 2072-09689-00 2-25 2-9.3.2  First-Time Operation  The internal GPS receiver is always powered when the transceiver is turned on. Therefore, if the GPS antenna is connected and you are in a good place with a clear view of the sky, the GPS receiver can start  the  satellite  acquisition process  as  soon  as the  transceiver  is  turned  on,  and can then  track the satellites continuously.   Thus,  the  GPS  item  on  the  FREQ  or  CH  menu  only  enables/disables the  display  of  GPS  data:  the result is that after selecting GPS, the GPS data can be immediately displayed, and is updated once per second (time is updated once every 5 seconds). Before  using  the  GPS  receiver,  turn  the  Micom-Z  transceiver  on  and  let  it  operate  for  at  least  15 minutes. 2-9.3.3  Operating Instructions 2-9.3.3.1  Switching to the GPS Display  NOTE You cannot switch to the GPS display if you are using the ALE mode. 1. Select  the  GPS  item  by  scrolling  with  the  MORE  key  on  the  FREQ  or  CH  menu,  and  then pressing F2. You will see a message that indicates the current display format, GPS LLA or GPS ECEF. 2. If necessary, switch to the alternate display format by pressing the UP or DOWN key. Alternatively, you can use the GPS menu: press MORE as required to see FMT, and then press the key next to FMT (F4).  3. If the GPS receiver operates normally and is ready, you will see the information selected the last time the receiver has been used.  2-9.3.3.2  Selecting what to Display 1. Press the key next to the type of information you want to see: use Figure  2-4 to find the key to be pressed. 2. The  displayed information  appears on the  display  and is automatically updated every  second. The time is updated every 5 seconds. 3. To change the display of GPS information, scroll to the desired item. 4. To cancel the display of GPS information, select any other menu except GPS. 2-9.3.4  What to do if … 1. If the GPS display mode, GPS LLA or GPS ECEF, does not appear when switching to the GPS display, scroll to the DEV item. You should see the GPS receiver type. • If you see UNKNOWN, turn the Micom-Z transceiver off and after a few minutes turn it back on. If the problem persists, the GPS receiver must be serviced. • If you see NONE, your Micom-Z transceiver does not include the optional GPS  receiver. 2. If the requested information does not appear within 15 minutes, but the check in Step 1 above is successful,  check  for  proper  connection  of  the  GPS  antenna  cable  to  the  rear  GPS  antenna connector of the transceiver. 3. After checking that the antenna is properly connected, check that the GPS antenna did not shift from its intended position, and has a clear view of the sky. Try to improve your location: avoid locations near trees, high buildings or steep hills.

OM-E 2072-09689-00 2-28 2-12.  USING AUTOMATIC LINK ESTABLISHMENT (ALE) The Micom-Z unit supports the Automatic Link Establishment (ALE) function, a method that enables automatically selecting the best  working  channel  from  a  group  of  preprogrammed  channels  without any user  intervention, thereby facilitating communication  among HF radio stations and improving  the communications  quality  and  reliability.  The  ALE  function  incorporates  all  the  advanced  data transmission  techniques  required  by  MIL-STD-188-141B  and  FED-STD-1045.  For  an  overview  of Micom-Z ALE capabilities and services, refer to Appendix A. The  ALE  function  ensures  the  best  possible  link  without  requiring  prior  knowledge  of  radio communication conditions, and thus enables reliable HF communication even under rapidly changing propagation conditions. For this purpose, HF radio sets using the ALE function continuously monitor and  evaluate  the  transmission  quality  on  each  frequency  assigned  for  communication,  and automatically select an optimal frequency for each transmission. After selecting the optimal frequency, a link between the communicating stations is established via an automatic handshake process, which is performed without requiring operator’s intervention. ALE  combines  sounding,  scanning,  selective  calling,  channel  selection  and  LQA  (Link  Quality Analysis). These features, all automatic, ensure that communication takes place on the channel with the best link quality, even with an unskilled operator. The ALE also includes many types of calls you can use to rapidly and efficiently set up links with other  ALE users, and features such as messages, stack and quick call. ALE supports many features, including: • Various type of calls • Up to 20 nets, each with its own set of members and associated frequencies (channels) • Up to 100 ALE addresses in the directory • Up to 100 scan channels • Up to 12 AMD (paging) messages. All the ALE features you can use on your radio can be programmed: to program or modify features, you  can  use  the  front  panel  of  the  radio,  as  described in  Chapter  4.  The  ALE  features  can  also  be preprogrammed using the MRC.  The following sections provide instructions for communicating in the ALE mode for a radio that has already been programmed with the necessary parameters in accordance with Chapter 4. Note that when the ALE mode is enabled, your radio can receive and transmit ALE calls even when you are using the Channel mode. For this purpose, the CALL key is  displayed even in the Channel mode (see Figure  2-2). The only restriction is that in the Channel mode, Micom-Z uses only the ALE parameters of net 1. Therefore, if net 1 is not programmed,  no ALE functionality is available in the Channel mode, even when the ALE mode is enabled. Note  that  the  radio  will  prevent  users  from  performing calls  on  Rx  only (RXO)  or  Tx  only  (TXO) channels. This is true even when operating in the Channel mode: when selecting a Rx Only or Tx Only channel, the ALE option is disabled (the CALL key is not displayed when such a channel is selected). 2-12.1  Enabling the ALE Mode To enter the ALE mode:  1. Press MENU to display the Menu screen. NOTE If you see CCIR or SCAN next to F3, first enable the ALE mode.  To  enable  ALE,  select  ALE  on  MENU  >  MORE  > PROG > RAD > OPTS > SLCL.

OM-E 2072-09689-00 2-30 2-12.3  Receiving and Transmitting Calls in ALE Mode The Micom-Z supports the following types of ALE calls: • Individual call – call directed to a specific station. • Net call – call directed to a net (a net is a preprogrammed group of stations).  • Group call – call directed to a group of stations. • AllCall – call directed to all other stations simultaneously (broadcast call); can also be used as a distress call. • AnyCall – call directed to all other stations simultaneously, usually used to detect new stations. • Wildcard call – call simultaneously addressed to a selected group of stations within a net, with wildcards used within the address to specify the desired stations. For efficient use of wildcards, an appropriate station naming plan must be in place. • Self call – call using the station’s own address, generally used for test purposes. • Bidirectional call – request for updating the LQA score with another station or stations. • Sounding call – used to build a link quality database. This database stores ongoing information on the current quality of the various channels programmed for use by your radio. All types of calls, except for sounding calls, can also carry messages. Using the ALE message service, you can also request remote stations equipped with GPS receivers to send their position. Moreover, if the GPS receiver of your radio is operational, you can also send your position to other radio sets. During ALE calls, a link is established between the stations participating in the call. During the link state, the radio operators have various  options, many of  them similar to  the options available in the Channel mode. For a description of the link options, see pages 2-31 to 2-34. 2-12.3.1  Receiving Calls in ALE Mode When  your  Micom-Z  receives  a  call,  it  displays  its  type  and  the  source address. You are also notified when a message is attached: if a message is received, the name of the calling station is preceded by an exclamation mark. For  any  type  of  call,  if  the  ALERT  attribute is  programmed  to  YES,  you will hear the alert tone when a message is received. FROM!1002 Receiving an individual call: When  an  individual  call  (i.e.,  a  call  addressed  only  to  your  station)  is received, the name of the calling station blinks in the display. FROM1002 NOTE If the calling station name is too long and does not  fit in  the display, < − >< − >< − >< − >  appears  next  to  F1.  Press  < − >< − >< − >< − >  to  enter  the  View  mode  (see page 2-7).  Receiving a net call: When your radio receives a net call (i.e., a call addressed to all the stations in your net), the display flashes a net call alert that alternates the words NET CALL with the calling station name.
OM-E 2072-09689-00 2-31 Receiving an AllCall: NOTE You can program your radio to ignore incoming AllCalls. If the radio is set  to  ignore  incoming  AllCalls,  it  stops  scanning  when  an  AllCall  is received but it does not display, nor lets you hear the call. At the end of the AllCall, the radio automatically returns to the scanning mode. When an AllCall is received, the display flashes an AllCall alert that alternates ALLCALL with the calling station name. Receiving an AnyCall: NOTE You can program your radio to ignore incoming AnyCalls. If the radio is set to ignore incoming AnyCalls, it stops scanning when an AnyCall is  received  but  it  does  not  display,  nor  lets  you  hear  the  call.  At  the end  of  the  AnyCall,  the  radio  automatically  returns  to  the  scanning mode. When an AnyCall is received, the display flashes an AllCall alert that alternates ANYCALL with the calling station name. Receiving a sounding call: When the radio is in the ALE mode and it receives a sounding call from another station, the calling station name appears in the display, preceded by the letter S to identify that the call is a sounding call.  Within a few seconds, the radio automatically returns to the mode used before the call was received. Receiving a bidirectional handshake call: When  the  radio  receives  a  bidirectional  handshake  call  from  another  station,  your  radio  responds automatically, without your intervention. Within a few seconds, the radio automatically returns to the mode used before the call was received. If the bidirectional handshake includes a message, the calling station name and the received message are stored in the stack, and the STAK function key appears. To answer an incoming call: Press any key (including PTT, but not ESC) to accept the call. The calling station name stops blinking, and is displayed steadily. The alert tone is no longer heard. The radio is now in the link state with the calling station. NOTE When an AllCall is received, no link is actually established but you can hear the calling station. If the received call includes a message, an exclamation mark precedes the station name, and the name is followed by a colon and the message. If the calling station name and message are too long and do not fit in the display, press < < < < − >− >− >− > to enter the View mode, where you can scroll right and left to display the whole message. To display LQA for the received call: Press LQA. You will see the channel in use, and its LQA score. 2-12.3.2  The Link State After the radio successfully receives or transmits a call, it is in the link state.
OM-E 2072-09689-00 2-32 If the call was received from another radio, the display includes the word FROM in the first line, as well  as  the  name  of  the  station  which  initiated  the  call  (if  a  message  has  been  received,  it  is  also displayed). If the call was initiated by your radio, the display includes the word LINK in the first line, as well as the destination address. While in the link state, you can operate the following functions using the function keys. NOTE The change of link options is temporary. When you exit the link state, all the changed parameters will be lost.  Option Description < − >< − >< − >< − > Activates the View mode, where you can view the entire station address. Page  Enables you to select a message to be sent to the station you are linked to. After a message is selected, you can edit it. The PAGE function is not available when receiving an AllCall. LQA   Displays the channel on which the link was established, and the LQA score of the current link. If the name of the station you are linked to is not in your directory, this function will not be available.  The LQA key is displayed only if you established the link in the ALE mode (in the Channel mode, this function is not available, because the call is received/transmitted on the current channel). MON   Turns on and off monitoring by means of the speaker. RPL  Replaces the currently-used channel with a channel with a better LQA score.  The radio disconnects the link, replaces the channel being used, and initiates the call once again. The RPL function is available only for individual calls, and only for the call initiator. The RPL key is displayed only if you established the link in the ALE mode (in the Channel mode this function is not available, because the call is received/transmitted on the current channel). BAND  Toggles between upper sideband (USB) and lower sideband (LSB). The sideband change takes places only after the current call is ended. SQ   Toggles the squelch on/off. Always select OFF for CW operation. DSP   Accesses the Digital Signal Processing menu, which includes the following options:  • CLAR   Enables to control the clarifier (off/lower frequency/higher frequency). The function key is not available for TXO (transmit only) channels.  • NF   Enables to control the notch filter (off/lower frequency/higher frequency). The function key is not available for TXO (transmit only) channels.  • CLIP  Toggles the clipper on/off.  • CC  Toggles the ClearCom function on/off.  • ATTN  Toggles the attenuator on/off. PWR  Selects the transmit power level: LOW – 25W; MED – 60W; HIGH – 100W; MAX – 125W. MODE  Selects the operation mode: • SSB – single sideband • AME – amplitude modulation equivalent • PLT – single sideband with pilot signal). AGC  Controls the automatic gain control function (fast/slow/off).
OM-E 2072-09689-00 2-33 Option Description BW  Selects the filter bandwidth.  • HS – high sensitivity filter (450 to 1500 Hz) for best voice communication under marginal conditions • 2.7 – 300 to 2700 Hz • 3.0 – 300 to 3000 Hz • 3.3 – 300 to 3300 Hz. Always select this bandwidths for data transmission  • LSM – bandwidth optimized for use with low speed modems (1450 to 1950 Hz) • CW (Continuous Wave or Morse operation). The bandwidth used in this case is selected by MENU > PROG > RAD > PRMT > CW. RCLV  Displays the receive level. The RCLV item appears only if the received signal level display is not permanently enabled using MENU > PROG > RAD > PRMT > RCLV. FREQ Displays the current frequency.  2-12.3.2.1  Replacing the Current Channel While in the Link State If during an individual call you find that the channel in use is not good enough, you can replace it with a better channel. NOTES •  Channel  replacement  is  possible  only  during  an  individual  call  in the ALE mode. •  Only the initiator of a call can replace the channel in use. To replace the channel: 1. Press MORE to scroll to the second link state menu. 2. Press RPL to replace the channel in use. 3. The radio disconnects the link, replaces the channel being used, and initiates the call once again. NOTE Even  if  a  message  was  transmitted  when  the  original  link  was initiated, the new link will be initiated without the message. 2-12.3.2.2  Using the Caller Stack The caller stack stores information about unanswered calls. The stack entry contains the self-address of the calling station, and any message sent by the calling station when it sent the call set up request. The stack can contain up to 10 calls. When the stack is not empty, you can see the stack icon in the display. The radio records an address in the stack only once, even if the same caller made several unanswered calls. However, if the same caller sent calls with different messages, all such calls will be saved in the stack.  If  you  see  STAK  in  the  options  area,  the  stack  includes  at  least  one  call  you  never  viewed before. The stack is arranged in FIFO order, that is, the first address that enters the stack is also the first that you see on the display. To view the calls in the stack: 1. Press  STAK.  The  radio  displays  information  on  the  total  number  of  calls  in  the  stack,  and information on the first call. If the number of characters exceeds the available space, press < − >< − >< − >< − > to activate the view mode. 2. Use the UP/DOWN keys to view any additional calls in the stack.
OM-E 2072-09689-00 2-34 To return a call to a station registered in the stack: 1. Press STAK. 2. Use the UP/DOWN keys to scroll to the required call. 3. Press CALL. 4. Press PAGE if you want to attach a message when you reply to the call. 5. Press CHAN if you want the call to be initiated on a specific channel in the currently used net. NOTE The CHAN key is displayed only if the radio is in the ALE mode. 6. Press SEND or ENTER to initiate the call. NOTE After initiating a call to a station, its page in the stack is automatically deleted, together with all other calls from the same address. To remove an address from the stack: The radio automatically removes an address from the stack in the following cases: • When  the  operator  calls  a  station  registered  in  the  caller  stack,  all  stack  calls  containing  that address are erased from the stack, regardless of whether the call was returned from within the stack or during an individual call. • The stack can contain up to ten addresses. When the stack is full and a new address comes in, the new address replaces the oldest address in the stack. In addition, you can manually remove an address from the stack as follows: 1. Press STAK. 2. Use the UP/DOWN keys to scroll to the required call. 3. Press ERAS. 4. Press YES to confirm or, NO to cancel the deletion. 2-12.3.3  Disconnecting Calls When you are in the link state, your radio can communicate with at least one other ALE station.  To disconnect an incoming call: Press the ESC key. This disconnects the link and returns the radio to the mode used before the link was  established.  When  you  disconnect  a  link,  you  can  instruct  the  other  station(s)  to  return  to  the working  mode  they  were  in  before  they  entered  the  link  state.  This  feature  is  called  Home Acknowledge, and can be programmed. If Home Acknowledge is enabled: • In an individual link, each of the stations in the link can transmit the Home Acknowledgement to instruct the other stations to disconnect the link. • In a net/AnyCall link, the Home Acknowledgement can only be transmitted by the radio which initiated the call. 2-12.3.4  Transmitting Calls in ALE Mode To transmit an  ALE call, you must specify the destination. In  general, the destination  consists  of  a  net  and  one  or  more  stations  (members  of  the specified net). The  destination net is  always the  currently selected  net (its number is displayed on the LCD while the radio is scanning).  ALENET     1      5LQACALLMON
OM-E 2072-09689-00 2-35 Therefore, if you do  not  want  to  select  a  different net,  you can skip directly to  the selection of  the destination station(s). To expedite the transmission of an AllCall, you can send a global AllCall by pressing the P/ESC key for a few seconds. Micom-Z  stores  the  last  called  address,  so  you  can  simply  press  the  PTT  twice  in  rapid  sequence (double pressing) to call again that address. This also applies to AllCall, and therefore after sending AllCall for the first time, you can send it again by double pressing the PTT. NOTE If you want to monitor the call set up process on the speaker and be alerted by a  beep when the link is  set up,  turn the monitor on, using the MON key. 2-12.3.4.1  Selecting the Desired Net To select a net: 1.

NOTE You can use this option to transmit a call to a station operating in the Channel mode. If the other station is in the Channel mode, your radio switches  to  the  Channel  mode  for  the  duration  of  the  call,  and  then returns to the ALE mode after the link to that station is disconnected. 4. Press SEND or ENTER to initiate the call. 5. The radio  now starts the link set up process. During this process, you will see TO alternating with  the  number  of  the  channel  on  which  the  set up  request  is  being  sent  (the  channel  may change, if the called station does not answer on the first channel(s)).
OM-E 2072-09689-00 2-37 NOTE While the radio is initializing the link, you can press STOP or ESC to abort the entire process. 6. After the link is established, you will see a LINK message. Now you may press the PTT and start talking. 7. To disconnect the link, press the ESC key (see page 2-31). 2-12.3.4.3  Quick Call A quick call is a call to the last station you tried to call (regardless of whether the call was successful or not). In the ALE mode, the channel used for the original call is reused for the quick call. The Quick Call feature can be enabled or disabled as part of ALE parameters programming. NOTES •  Quick  Call  will  not  transmit  a  message,  even  if  the  last  call contained a message. •  The first time the station is switched to the ALE or Channel mode, quick call is not possible as no "most recent" station data exists. To send a quick call: Double-press the PTT of your microphone or handset. The radio automatically tries to contact the last called station. During this process, you will see TO alternating with the number of the channel on which the set up request  is  being  sent  (the  channel  may  change,  if  the  called  station  does  not  answer  on  the  first channel(s)). NOTE While the radio is initializing the link, you can press STOP or ESC to abort the entire process.  2-12.3.4.4  Using Autodial The  Autodial  feature  lets  you  use  a  single  digit  to  call  a  preprogrammed  address.  There  are  ten programmable Autodial addresses, where each can include a message. To use Autodial to send a call: 1. Press # on the keypad. NOTE If you do not select an auto-address within a few seconds, the display automatically reverts to the previous state. 2. Press the desired preprogrammed Autodial number (0 to 9).

Option Capabilities  See Page … ALL  AllCall – call directed to all the other stations simultaneously; usually used as a distress call. 2-40 NET  Net call – call directed to a net (a net is a preprogrammed group of stations). Up to 20 nets can be defined. 2-41 GRP  Group call – call directed to a group of individually selected stations. Groups can  be preprogrammed, but  you can also  select the stations to  be  called and save the selection for reuse. Up to five groups can be defined. 2-42 ANY  AnyCall – call directed to all the other stations simultaneously, usually used to detect new stations. 2-44 WILD  Wildcard call – call simultaneously addressed to a selected group of stations within  a  net,  with  wildcards  used  within  the  address  to  specify  the  desired stations. Wildcard calls use the special ALE addressing modes. If you are not familiar with these modes, you should review Appendix A. 2-45
OM-E 2072-09689-00 2-40 SELF  Self  call  –  call  using  the  station’s  own  address,  generally  used  for  test purposes. 2-46 2-12.3.4.7  Transmitting AIICalls An  AllCall is a message which your  radio  uses to establish  a  connection  with all the other stations simultaneously, and is  typically used to broadcast a message or  send a  distress call. An AllCall can also include a message. In  addition  to  this  type  of  AllCall  (referred  to  as  a  global  (GL)  AllCall),  it  is  also  possible  to  use selective  (SL) AllCall:  this  is  a  simultaneous  call  addressed  only  to  all  the  stations  whose  names (addresses) end with a character you specify.  NOTE If so required, you can set your radio so that it cannot send AIICalls. You cannot select the channel on which an outgoing AllCall will be sent: outgoing AllCalls are sent on the AllCall channel defined for the currently selected net, or on the best scanned channel of the net. There  are  two  ways  to  send  a  global  AllCall:  using  the  ESC  key  or  using  the  CALL  function.  A selective AllCall can be sent only using the CALL function. To send global AllCall using the ESC key: 1. Press ESC continuously for a few seconds. The radio starts sending the GL AllCall. During this process, you will see TO alternating with the number of the channel on which the set up request is being sent.

NOTES •  You can program nets using the front panel, or the MRC. •  The radio must be programmed as a MASTER radio in the net (an ALE Programming option) in order to be able to transmit net calls.  To transmit a net call: 1. Press CALL. The radio displays the last called address. If you see the net you want, skip directly to Step 5 below, otherwise continue as explained below. 2. Select the NET option as explained on page 2-39. 3. Press PAGE if you want to attach a message to the call. 4. Press CHAN if you want to initiate the call on a specific channel. 5. Press SEND or ENTER to initiate the call. The radio now starts the link set up process. During this process, you will see TO alternating with the number of the channel on which the set up request is being sent. NOTE While the radio is initializing the link, you can press STOP or ESC to abort the entire process.
OM-E 2072-09689-00 2-42 When a net call is transmitted, each member in the net responds to the call and the initiator of the call receives an indication of the response on the display. 6. After links have been established, you can start talking. 7. To end the call, press ESC. 2-12.3.4.8  Transmitting Group Calls Group calls let you call several individual stations in your net (at least 2) at once. Thus, you can use a group  call  to  communicate  with  a  few  select stations, while  other stations  can still  communicate  at will, using other channels available to your net. You  can  call  up  to  5  stations  in  a  group call. The  only restriction is  that  the  total  length  of  all  the addresses cannot exceed 12 ALE words (36 characters). If the maximum allowed length is exceeded, you get a BUFF FULL error. NOTES •  If  you  need  to  check  beforehand  the  length,  remember  that each ALE word must include 3 characters. Therefore, when an address is  not  an  exact  multiple  of  3,  stuffing  symbols  are  automatically added in the last positions. •  ALE  addresses  are  categorized  in  accordance  with  their  leading ALE word (that is, their first three characters: if the address is short and  has  only  one  or  two  characters,  stuffing  symbols  @  are added).  When  assembling  a  group  you  must  also  take  into consideration  that  the  maximum  number  of  different  address categories (as identified by their leading word) in one group is 5. If more are included, then when you try to send the call you will see UFA WRONG. In this case, remove addresses to make the group more homogenous. To make a group call, first you must specify the stations to be included in the group. The addresses of the  stations you include in the  group can be saved as  a group;  the radio can store  up  to 4  different groups. If a group including the desired stations is already programmed, you can directly initiate the call to the desired group. NOTE Before  starting,  you  may  want  to  select  a  different  net  to  use:  see instructions on page 2-35.  To transmit a group call: 1. Press CALL. The radio displays the last called address. If you see the group you want, skip directly to Step 6 below, otherwise continue as explained below. 2. Select the GRP option as explained on page 2-39. 3. The first group displayed is always group 1. If this is the group you want, skip directly to Step 6 below, otherwise press the UP or DOWN arrows until you see the desired group. 4. Press PAGE if you want to attach a message to the group call. 5. Press CHAN if you want to initiate the call on a specific channel. 6. Press SEND or ENTER to initiate the call.
OM-E 2072-09689-00 2-43 NOTES •  If  the  selected  group  does  not  include  at  least  2  stations,  your request is rejected and you will see for a few seconds AT LEAST 2. •  If  the  addresses  in  the  group  have  more  than  5  different  leading words,  your request  is rejected  and you  will see for a few  seconds UFA WRONG. The radio  now starts the link set up process. During this process, you will see TO alternating with the number of the channel on which the set up request is being sent. NOTE While  the  radio  is  initializing  the  link,  you  can  press  STOP  or  ESC  to abort the entire process. When a net call is transmitted, each member in the group responds to the call and the initiator of the call receives an indication of the response on the display. 7. After links have been established, you can start talking. 8. To end the call, press ESC. To define or change a group: 1. Press CALL and select the GRP option, as you do to start a group call (page 2-42). 2. The first group displayed is always group 1. If this is the group you want, skip directly to Step 3 below, otherwise press the UP or DOWN arrows until you see the desired group. 3. To select the stations you want in this group, press SEL. NOTE The following example explains how to build a new group, but you can use the same procedures to change an existing group. 4. After pressing SEL, you will see the DIR  screen. Therefore, you can select stations  from the addresses already stored in the directory, or type new addresses using the keypad. To select an address from these already in the directory: 1. Use the UP and DOWN arrows to display the desired directory entry, and then press ADD. The label above the selected entry changes to ADDED, to indicate that it is now included in the group. Now you can also have the option (ERAS ) to delete the entry from the group. NOTE If  adding  the  station  would  cause  the  total  length  of  the  station addresses in the group to exceed 12 ALE words, then after pressing ADD you will see BUFF FULL and the process stops. 2. Repeat the procedure described above until the group includes only the desired stations. As you scroll through the directory, you will see DIR for stations that can be added, and ADDED for those already added. If the station you want to add to the group is not in the directory: Enter the new station using the keypad. If you make a mistake, scroll to the desired position using < − −< − −< − −< − − and/or − − >− − >− − >− − >, or clear (CLR ) the whole entry and start again. 3. When ready, press SAVE to store the new station in the directory.
OM-E 2072-09689-00 2-44 Now you can add it to the group by pressing ADD. 2-12.3.4.9  Transmitting AnyCalls An AnyCall is a general broadcast which your radio uses to simultaneously establish links with other stations. An AnyCall can also include a message. NOTE If so required, you can set your radio so that it cannot send AnyCalls. AnyCall is somewhat similar to AllCall, except that it requests responses from the other stations and therefore  it  can  be  used  to  detect  new  stations.  Another  difference  is  that  you  can  also  select  the channel  on  which  the  AnyCall  will  be  transmitted  (alternatively,  you  can  let  the  radio  select automatically the channel). You can send three types of AnyCalls (see also description of addressing modes on Appendix A): • General: the address sent by your radio is @@?. This is a simultaneous call addressed to all the stations. • Selective: you  specify  the last character  of  the address.  This  is  a  simultaneous  call  addressed only to the stations whose names (addresses) end with a character you specify. • Double  selective:  similar  to  selective,  except  that  you  specify  the  last  two  characters  of  the address.  To make an AnyCall, first you must select the address to be used for the call. Micom-Z will wait for responses for a certain time before entering the link state with all the stations that responded within this interval (the maximum number of stations that are accepted in an AnyCall is 16). NOTE Before  starting,  you  may  want  to  select  a  different  net  to  use:  see instructions on page 2-35.   To transmit an AnyCall: 1. Press CALL. The radio displays the last called address. If you see the address you want (that is, you want to repeat the last AnyCall), skip directly to Step 10 below, otherwise continue as explained below. 2. Press MORE once. 3. Press MULT to display the first page of special calls. 4. Press ANY. 5. Press SEL.  NOTE If  you  try  to  send  (SEND)  the  call  without  first  selecting  an  address, your attempt is rejected and you see for a few seconds NOT PROG. 6. Select the AnyCall address: • To send a general AnyCall, press ?. • To send a selective AnyCall, enter the desired character (any character except #, @ or ?). • To send a double-selective AnyCall, enter two characters. 7. Confirm your selection by pressing ENTER.
OM-E 2072-09689-00 2-45 8. Press PAGE if you want to attach a message to the call. 9. Press CHAN if you want to initiate the call on a specific channel. 10. Press SEND or ENTER to initiate the call.  The radio now starts the AnyCall process. During this process, you will see TO alternating with the number of the channel on which the request is being sent. NOTE You can press STOP or ESC to abort the entire process. When an AnyCall is transmitted, the initiator of the call receives an indication of each station answering the call (its address flashes in the display, until replaced by the next answering station). 11. After  a  programmed  interval  (or  after  16  stations  answer,  whichever  comes  first),  the  link  is established. Now you can start talking. 12. To end the call, press ESC. 2-12.3.4.10  Transmitting Wildcard Calls Wildcard calls, that is, calls in which the destination address includes the wildcard character ?, let you to simultaneously address multiple stations with a single address:  • Any station receiving an address with wildcards stops scanning and checks the address length: if the number of characters in the received address is different from the number of characters in its own self-address, the station ignores the call. • If the received address matches the length, a receiving station checks the significant positions in the received address against its own. For example, the stations JOHN and JOIN will both accept a call with the address JO?N. • Each station accepting the call answers the calling station in a pseudo-random slot.  Micom-Z will wait for responses for a certain time before entering the link state with all the stations that responded within this interval (the maximum number of stations that are accepted in a wildcard call is 16). Therefore, with the wildcard option, the link set up process takes more time, because the radio waits longer to get responses (it cannot “guess” the number of stations that will answer). Before continuing, you may wish to review Appendix A, which presents details on  ALE addressing (including the use of wildcards in addresses). NOTE Before  starting,  you  may  want  to  select  a  different  net  to  use:  see instructions on page 2-35.  To transmit a wildcard call: 1. Press CALL. The radio displays the last called address. If you see the address you want (that is, you want to repeat the last wildcard call), skip directly to Step 11 below, otherwise continue as explained below. 2. Press MORE once. 3. Press MULT to display the first page of special calls. 4. Press MORE again to display the next page. 5. Press WILD to start. 6. Press SEL.
OM-E 2072-09689-00 2-46 NOTE If you try to send (SEND ) the call without first selecting an address, your attempt is rejected and you see for a few seconds NOT PROG. 7. Select the desired address: • To insert a wildcard, press ? • Enter the desired characters using the keypad. 8. Confirm your selection by pressing ENTER. 9. Press PAGE if you want to attach a message to the call. 10. Press CHAN if you want to initiate the call on a specific channel. 11. Press SEND or ENTER to initiate the call. NOTE If the selected group does not include at least 2 stations, your request is rejected and you will see for a few seconds AT LEAST 2. The  radio  now  starts  the  process.  During  this  process,  you  will  see  TO  alternating  with  the number of the channel on which the request is being sent. NOTE You can press STOP or ESC to abort the entire process. 12. After a delay, you will see LINK with the wildcard address flashing. 13. Confirm the link set up by  pressing ENTER or the PTT. The address stops  flashing, and you can start talking. 14. To end the call, press ESC. 2-12.3.4.11  Transmitting a Self Call The self-call is a test call addressed to your own address within the currently selected net. Its purpose is to check that your radio set is OK and can transmit calls (to check reception, you can simply listen to other radio sets). When you send the self-call,  the radio  starts sending calls to its own address, successively, on  each channel  in  the  current  net.  After  going  through  all  the  channels,  the  call  process  stops.  No  other response is expected. NOTE You can also include the self address in a group call.  To send a self-call: 1. Press CALL. The radio displays the last called address. 2. Press MORE once. 3. Press MULT to display the first page of special calls. 4. Press MORE again to display the next page. 5. Press SELF to start the self-call. 6. You may select now a specific channel to perform the call, by pressing CHAN. See details on page 2-36.
OM-E 2072-09689-00 2-47 7. When ready, press SEND to start transmitting. The display alternates between your self-address and the channel used for the call is sent.  If you did not  select a  specific channel, the channel number changes as the radio sends the call on each channel assigned to the selected net. After all the channels have been used, the call automatically stops. You can press STOP at any time to end the call sooner. 2-12.3.4.12  Bidirectional Handshake The bidirectional handshake is used to exchange LQA scores with other stations without establishing a link. NOTE The Micom-Z can also be programmed to automatically initiate the call to  the  station  after  finishing  the  bidirectional  handshake  (using  the BDLK parameter reached under the ALE programming options). A bidirectional handshake can be carried out with a single station or with all stations in the net. It can be carried out either on a single channel, or on all the net channels. When required, a message can also be added to the procedure. After  a bidirectional handshake  with  a  single station,  the  LQA matrices  of  both radios are updated. The operator can then initiate a call to that station and obtain the best channel automatically. When the bidirectional handshake procedure is performed with a net, all the stations in the net update their LQA tables. Micom-Z will wait for responses for a certain time before entering the link state with all the stations that  responded  within  this  interval  (the  maximum  number  of  stations  that  are  accepted  in  a bidirectional handshake is 16). NOTE Before  starting,  you  may  want  to  select  a  different  net  to  use:  see instructions on page 2-35.  To execute a bidirectional handshake with an individual station: 1. Press LQA to enter the LQA menu. 2. Press BIDR. The last called address is displayed. If this is the address you want, skip directly to Step 6 below. 3. To select a different address, use the UP/DOWN keys to  scroll to the required address in the directory, and then press ENTER to confirm your selection. or If the station you want to add to the group is not in the directory: • Enter the new station using the keypad. If you make a mistake, scroll to the desired position using < − −< − −< − −< − − and/or − − >− − >− − >− − >, or clear (CLR) the whole entry and start again. • When ready, press SAVE to store the new station in the directory. 4. Press  PAGE  if  you  wish  to  attach  a  message  to  the  bidirectional  handshake  process.  After confirming the message, exclamation mark precedes the name of  the called station, indicating that a message has been attached. 5. Press CHAN if you wish to execute a bidirectional handshake process on a specific channel. 6. Press  SEND  or  ENTER  in  order  to  initiate  the  bidirectional  handshake  process.  During  this process, you will see TO alternating with the number of the channel on which the set up request is being sent.
OM-E 2072-09689-00 2-48 NOTE During  the bidirectional  handshake  process,  you can press STOP or ESC to abort the entire process. To execute a bidirectional handshake with a net: 1. Press LQA to enter the LQA menu. 2. Press BIDR. The last called address is displayed. If this is the net you want, skip directly to Step 8 below. 3. Press MORE. 4. Press MULT. 5. Press NET. NOTE You  cannot  change  the  net  number  at  this  stage  –  the  bidirectional handshake  is  always  performed  on  the  currently  selected  net.  To change the net, see page 2-35. 6. Press PAGE if you want to attach a message to the handshake. 7. Press CHAN if you want to initiate the handshake on a specific channel. 8. Press  SEND  or  ENTER  to  initiate  the  handshake.  During  this  process,  you  will  see  TO alternating with the number of the channel on which the handshake is being sent. NOTE While the radio is initializing the  handshake,  you can press STOP or ESC to abort the entire process. 2-12.3.4.13  Sounding Sounding is used to test the quality of the channels and propagation paths of all channels in the net. The  sounding  signal  is  normally  repeated  automatically,  at  regular  intervals.  A  complete  round  of sounding messages, or "sounding cycle" can be programmed to 30, 60, 90, or 120 minutes, or can be set to OFF. Sounding can also be initiated manually whenever necessary, even if automatic sounding is enabled. To manually initiate sounding: 1. Press LQA to enter the LQA menu. 2. Press SOND. 3. Press ON to start manual sounding, or OFF to stop an ongoing sounding process. NOTES •  The  radio  automatically  returns  to  ALE  mode  when  sounding  is stopped. •  When the radio transmits a sounding signal, the Tx bar is visible. 2-12.3.5  Using the Inlink Function When the inlink function is enabled, the stations participating in a call are automatically notified by a DISC message whenever another participant leaves (disconnects from) the call.
OM-E 2072-09689-00 2-49 The link is  then  automatically disconnected when only one station is left (that is, after all  the other participants disconnected). The  inlink  function  is  available  in  any  type  of  call  that  involves  the  setting  up  of  a  link  using bidirectional handshaking. Therefore, you can use it in individual calls, group calls, net calls, etc., but not in AllCalls and self calls. NOTE For  the inlink function to  operate correctly, it must  be  enabled on all the stations. Do  not  enable  the  inlink  function  when  communicating  with  a  radio that  does  not  support  the  full  ALE  capabilities  in  accordance  with MIL-STD-188-141B. To avoid disconnecting the link too soon as a result of inactivity (that is, after the programmed PTT time-out  interval  (PTOT)),  each  participant  can  request  other  stations  to  wait  beyond  the  PTOT interval (up to 10 minutes more) before automatic disconnection occurs. This option (TOT – time-out interval) is displayed over the F4 key after the link is set up: to send a request for the other stations to wait more time, press the TOT key. 2-12.3.6  Transmitting ALE Calls in the Channel Mode The  ALE option is available in both  the  ALE and Channel  modes and  therefore,  the radio can also answer ALE calls. The transmission process is similar for both operating modes, with the following differences: • In the Channel mode, every call is initiated on the currently selected channel. • The LQA function is not available in  the Channel mode:  sounding and bidirectional calls  can only be initiated in the ALE mode. • When the radio is in the Channel mode, it uses the parameters programmed for net 1.  NOTE If  net  1  is  not  programmed,  there  is  no  ALE  functionality  in  the Channel mode, even if the ALE option is turned on.  2-12.4  Using ALE Mode to Send and Request GPS Position Data You can use the ALE AMD service to: 1. Send your position to any another destination (including one-to-many). 2. Request the position of  another  Micom-Z transceiver equipped with  a  GPS receiver. You can make this type of request only when you call an individual station. Note  that  the  operations  described  above  automatically  set  up  a  link  between  the  two  stations  and therefore  it  is  necessary  to  disconnect  the  link  when  it  is  no  longer  needed.  For  this  purpose,  it  is recommended to enable Home Acknowledge, and/or enable the PTT time-out function.
OM-E 2072-09689-00 2-50 NOTE AMD  messages  with  the  GPS  position  do  not  enter  the  stack  (the information such message carries is good only at the time you got it): if you do not read the message in time, you can no longer retrieve the message at a later time. Thus, you must allow sufficient time for the destination station to read the  position  message  before  when  link  is  disconnected.  This  is particularly  important  when  Home  Acknowledge  is  enabled:  the message will disappear as soon as you disconnect the link. 2-12.4.1  Request GPS Position To automatically get the position of another Micom station, use the following procedure: 1. Select the CALL mode (either from the ALE mode or the CHAN mode). 2. Select the destination address (you can make only an individual call). 3. Select the PAGE selection mode. 4. Scroll until you see the RMT POS message, and then send the message. 5. Your station starts the link set up to the selected station; after the link is set up, you will see the response  AMD  of  the  called  station,  which  includes  its  latitude  and  longitude.  POSITION INVALID means that the remote station cannot provide its location. 6. You may now continue with voice communication, or disconnect the link to the called station. NOTE Radio sets of various vendors can also accept GPS position requests. The  position request is made by  sending  the string FIXPOSIT  as  an AMD message. 2-12.4.2  Sending Own GPS Position You can use the PAGE service to send the AMD message that appears in position 14 in the default list of AMD messages to transmit your own position to a remote station.
OM-E 2072-09689-00 2-51 2-13.  USING THE CCIR MODE The  automatic  link  establishment  protocol  standardized  by  CCIR  (Consultative  Committee  on International Radio, currently part of the International Telecommunications Union) is a protocol that provides  services  similar  to  the  ALE  protocol  (see  para.   2-12),  except  that  it  uses  a  different addressing  scheme,  based  on  six-digit  station  addresses  with  support  for  four-digit  addresses  for backwards compatibility. In the CCIR mode, you can enable the SCAN mode. In the SCAN mode, the radio scans a specified group of channels programmed into the radio set, in which case the radio can receive calls on any of the scanned channels. The operator can however manually select the channel on which to transmit a call. To use the CCIR mode, it is necessary to configure directory entries (at least one). For more details, see the Configuring CCIR Directory Entries section in Chapter 4. In addition, to use the CCIR scanning mode, it is necessary to program CCIR groups, using the MRC. The main services available with the CCIR protocol are as follows: • Receive calls from individual transceivers, as well as groups and subgroups of transceivers  • Call individual transceivers, as well as groups and sub-groups of transceivers  • Transmit text messages, beacon calls, and emergency calls. 2-13.1  Enabling the CCIR Mode To enter the CCIR mode: 1.

OM-E 2072-09689-00 3-1 CHAPTER 3  INSTALLATION 3-1.  SCOPE This Chapter provides installation instructions for Micom-Z. The information presented in this Chapter includes: • Unpacking – para.  3-2. • Installation planning guidelines – para.  3-3. • Installation procedures for Micom-Z – para.  3-4,  3-5 and  3-6. • Post-installation checks – para.  3-7.   Do  not  touch  the  antenna  and  the  RF  connectors  when  the Micom-Z is turned on. Make sure that the antenna is not located near high-voltage lines. During  transmission,  high  RF  voltages  appear  at  the  RF connectors, the antenna cables, and on the antenna itself. These voltages may cause severe injury or death on contact. Operating  and  maintenance personnel  must  be familiar  with  the applicable safety requirements and regulations before attempting to  install  or  operate  Micom-Z  radio  sets.  Severe  injury  or  death could result from failure to comply with the safety practices. 3-2.  UNPACKING a. A  preliminary  inspection  of  the  equipment  containers  should  be  made  prior  to  unpacking. Evidence of damage should be noted and reported immediately to the proper authorities. Unpack the equipment as follows:  (1) Place each container on a clean flat surface, cut all straps, and open or remove the top.  (2) Take out each item carefully and place it securely on a clean surface.  (3) Remove the packing material while looking for small items.  (4) Fold  and  store  the  containers  and  packing  materials  in  accordance  with  standard procedures.  b. Checking Unpacked Equipment.  (1) Inspect all items for damage. Immediately report any damage found.  (2) Check  all  items  against  the  items  listed  in  the  accompanying  packing  slip  and/or  the appropriate list of items given in the equipment manuals.  (3) Report any missing items or discrepancies. Shortage of a minor part which does not affect the proper functioning of the equipment should not prevent use of the equipment.
OM-E 2072-09689-00 3-2 3-3.  INSTALLATION PLANNING GUIDELINES This section provides the information necessary for planning the installation of Micom-Z equipment. The information presented in this section is applicable to both fixed station and mobile installations. 3-3.1  Location Select the radio location for convenience of access to electrical connections and for maintenance. The selected  location  should  be  clean,  dry  and  well  ventilated.  Do  not  mount  the  equipment  in  close proximity to strong electrical fields produced by brush motors and generators, welders, etc. In general, the antenna, antenna tuner (when used), and associated cable kits are provided separately. These  should  be  installed  before  the  radio  is  installed  with  each  item  (refer  to  the  corresponding manuals for installation data). The radio may be placed on any sturdy, flat surface. A mounting tray allows the radio to be mounted in  any  location.  Before  installing  the  radio,  read  the  entire  installation  procedure  detailed  in  this section. Follow the instructions carefully. 3-3.2  Power Requirements The Micom-Z requires DC power at a nominal voltage of 12 VDC (negative pole grounded). For fixed (base) stations, when AC power is available, you can use a DC power supply to provide the required DC voltage, for example, FPN5600, to provide the required DC voltage.  It is recommended to connect a 12 V backup battery with a capacity of 80 Ah to the battery terminals of  the  power  supply.  Therefore,  when  AC  power  failure  occurs,  the  battery  functions  as  the  main power source. When AC power is again available, the power supply charges the battery. Make sure to select a DC power supply that can also serve as a charger for the backup battery. Contact manufacturer for recommended DC power supply/charger types. CAUTION Use  a  30A  protection  fuse  in  series  with  the  positive  battery terminal. Risk  of  explosion  if  incompatible  battery  is  used,  or  battery  is incorrectly connected! ++__Connect hereAC power cableConnect toprotective ground using wide copper strap12V BatteryFuse30ABlackRedToRadioRADIOTerminalsBATTERYTerminalsFuse30A Figure  3-1. FPN5600 Power Supply Connections
OM-E 2072-09689-00 3-3 3-3.3  Grounding The  resistance  measured  between  the  Micom-Z  body  and  the  system  ground  should  be  as  small  as feasible. Failure to provide proper grounding will degrade system operation and cause RF voltage to be present on the equipment chassis.  Wide  copper  straps,  as  short  as  possible,  should  be  used  for  grounding.  These  straps  should  be clamped or bonded to the vehicle body.  For vehicular installations, the vehicle body must be properly grounded during fixed station use. This can be achieved by means of ground rods. Where the soil is dry and sandy, ground radials should be used.  3-3.4  Vehicular Noise Reduction Most vehicles  contain several  noise sources  which can greatly disturb  radio reception (for example, the high voltage ignition sparks that are produced at the vehicle's plugs, and the alternator activity). If necessary, install a noise reduction kit. 3-3.5  Antenna and Antenna Tuner Unit (ATU) For fixed stations, dipole and broadband antennas, which provide a nominal impedance of 50 Ω, can be used. In such applications, the antenna can be directly connected to the Micom-Z ANT connector. For  other  applications,  and  in  particular  when  using  whip  antennas,  long  wire  antennas,  and  any antenna which does not present a 50 Ω impedance over the full operating frequency range, an antenna tuner unit (ATU) is necessary. Suitable ATUs, for example, F2265 and FLN2818, are available from the manufacturer; these ATUs can be used in both mobile and base station applications. An externally mounted mobile automatic antenna system, FAD1410, is also available. The  recommended  vehicular  whip  antenna  is  FAD1400,  also  available  from  the  manufacturer.  To achieve  maximum  operating  range,  the  antenna  should  be  mounted  as  high  on  the  vehicle  body  as possible  without  striking  overhead  obstructions  in  the  normal  service  area  of  the  vehicle.  Select  a mounting  location  on  a  flat    portion  of  the  vehicle  body,  compatible  with  the  maximum  allowable length of the ATU lead-in cable.  For short range communications (ground waves), a vertical (non-bent) antenna is preferred. For long range  communications (sky waves),  a  bent  antenna  is  preferred.  The  antenna  may  be  bent  and  tied down to the vehicle's body with a nylon cord. The best antenna location is the vehicle rooftop, where the antenna is not obstructed by metal objects. Roof  center  installation  provides  good  symmetrical  omnidirectional  radiation  patterns.  If  roof  top installation is impossible, a side wall installation, with the antenna as far away from the side wall and as high as possible, will suffice. If the antenna's height above ground is limited, it is preferred to install the antenna as  high as possible and to bend and strap it  down to the required height (as opposed to installing the antenna close to the ground, such as in a bumper mounted installation).  Suggested mobile installations are illustrated in Figure  3-2. Figure  3-3 shows options for installations using FAD1410.
OM-E 2072-09689-00 3-4  Figure  3-2. Suggested Mobile Installations Using ATU  Figure  3-3. Suggested Mobile Installations Using FAD1410 3-3.6  GPS Antenna If  you  will  use  the  integral  GPS  receiver  of  your  radio  set,  then  it  is  necessary  to  select  a  suitable location for the GPS antenna. 3-3.6.1  GPS Antenna Description The  GPS  antenna  is  a  compact  active  omnidirectional  antenna  with  magnetic mounting,  which  attaches  easily  and  firmly  to  vehicle’s  steel  body  parts,  even when painted. The antenna will not attach to non-magnetic alloys (e.g., aluminum alloys), nor to parts made of composite materials (e.g., fiberglass).  The antenna connects to the GPS connector of  the Micom-Z transceiver through a 5-meter (15 feet) long coaxial cable, which is part of the antenna. This cable carries both DC power for the antenna, and the received GPS signals.  The antenna is 42 mm wide by 50.5 mm long by 13.8 mm high (1.65”×1.99”×0.55”), and it requires a minimal ground plane of 60 by 60 mm (2.36”×2.36”) to provide the specified performance.
OM-E 2072-09689-00 3-5 3-3.6.2  Selecting a Proper Location for the GPS Antenna  GPS  satellites  transmit  their  special  signals  in  the  1575  MHz  range:  such  signals  do  not  penetrate conductive surfaces. When selecting the location of the GPS antenna, you should also be aware that strong local interference as well as reflections from nearby objects may disrupt normal reception and degrade the signal quality. Thus, the GPS antenna should be installed on horizontal surfaces, in a place that provides a clear view of the sky, which, in as far as possible, is not obstructed by large objects. For example, the roof of the passenger’s cabin is a good place for the GPS antenna.  Moreover,  you  should  not  park  the  vehicle  under  dense  foliage  or  other  cover,  for  example,  in  a garage, if you want to get a position fix from your GPS receiver.  NOTE When the GPS antenna is installed on a metal surface for prolonged periods,  care  must  be  taken  to  insulate  the  antenna,  to  prevent galvanic corrosion. After  installing  the  antenna, route  its  cable  to  the  GPS connector  on  the  rear  of  the  Micom-Z, and make sure to avoid running it parallel to the other transceiver cables. 3-3.7  Cooling Micom-Z  units  are  cooled by free  air  convection. Therefore,  make sure  that  sufficient  free space is available around the equipment to enable free air flow. When  it  is  necessary  to  use  Micom-Z  in  applications  that  require  continuous  transmission  for prolonged intervals, it is recommended to install Micom-Z on the optional cooling tray. 3-3.8  Installation Data All the dimensions are in mm. 3-3.8.1  Dash-Mount Micom-Z Model Figure  3-4 shows the dimensions of the dash-mount Micom-Z transceiver model.

When ready to  apply DC  power, connect the  plug of the DC power positive (red) lead  to the jack of the red extension lead. 3-6.  INSTALLATION OF MICOM-Z ON COOLING TRAY When  installing  the  Micom-Z  radio  set  on  the  cooling  tray,  you  can  follow  the  same  procedures described above in para.  3-4 or  3-5 except for the details related to the cooling tray. The specific steps needed to install a Micom-Z transceiver on the cooling tray are described below. 3-6.1.1  Preparing the Cooling Tray for Installation In static stations, there are no preparations – simply place the cooling tray in the prescribed position. For mobile stations, it is necessary to fasten the tray to the mounting area as explained in para.  3-6.1.2. For this purpose, you must remove the feet attached to the tray, to free the installation holes (the feet are fastened by screws). The installation hardware supplied with the cooling tray includes two sets of four  screws  (one  set  for  attaching  the  tray  to  a  wooden  surface,  and  the  other  set  –  for  metallic surfaces). 3-6.1.2  Installing the Cooling Tray To  install  the  Micom-Z  cooling  tray  in  the  prescribed location, proceed as follows: 1. Check  the  mounting  surface  and  the  holes  used to  attach  the  cooling tray.  Thoroughly clean the mounting  surface  and  remove  all  paint,  grease and  dirt  from  the  holes  in  order  to  provide  a better grounding connection. 2. Place  the  tray  in  the  prescribed  location,  and align  its  holes  with  the  holes  on  the  mounting surface. 3. Insert a bolt with springwasher through each tray hole, and screw it into the corresponding hole of the mounting surface. Tighten securely each bolt, using  the  Allen  wrench  supplied  in  the installation kit. NOTE If the holes in the mounting surface do not include  threaded  inserts,  use  nuts  with toothwashers.  CAUTION Before  installing  the  transceiver,  carefully inspect  the  cooling  tray,  and  clean  the area  from  dirt.  Remove  dust,  and  any foreign  object  that  may  prevent  free rotation of the fan.  TrayTransceiverFastener
OM-E 2072-09689-00 3-14 4. Release the transceiver fastener, and insert the transceiver until its rear engages the stop bar of the tray.  Make sure that the transceiver heatsink fins fit around the fastener sides. Check that the transceiver sits well within the tray, and that its heatsink is horizontal and touches the tray along its whole length. 5. Tighten the fastener with an Allen wrench, to secure the transceiver safely within the tray. 6. Connect the grounding strap to the vehicle body, as shown in Figure  3-9 or Figure  3-11. 7. Connect  the  44-pin/25-pin  adapter  cable  between  the  ACCESSORY  connector  of  the transceiver and the TO RADIO connector on the cooling tray. 3-6.1.3  Connecting to the Cooling Tray At  this  stage,  you  may  start  connecting  cables  to  the  transceiver  as  explained  in  para.   3-4  or   3-5, respectively. The only differences are as follows: 1. Connect  the  equipment  to  the  ACCESSORY  connector  on  the  cooling  tray,  instead  of  the connector located on the transceiver. 2. You can connect a headphone set and a telegraphy (Morse) key to the corresponding front jacks of the cooling tray. 3-7.  CHECKING INSTALLED EQUIPMENT  The purpose of the checks is to verify that the equipment has been properly installed and is ready for communication.  If  a  problem  is  detected  during  the  checks,  use  para.   3-7.2  to  identify  the  source  and  return  the equipment as soon as possible to operational condition, by replacing cables, accessories, or equipment units suspected of being defective. 3-7.1  Operational Checks When installation is complete, perform a visual inspection, to ensure that the radio equipment and the antenna system have been properly installed, and then carefully check all the operational functions of the radio set. Whenever possible, perform a communication check with one of the other radio stations in your net. When using the cooling tray, make sure that the fan rotates freely, without any unusual noises (upon power-up, the fan is automatically activated for 10 seconds). 3-7.2  What to Do If ... 3-7.2.1  Preliminary Checks In case a problem is detected, or the radio set fails to operate, perform the following steps: 1. Visually inspect the radio set, and make sure that the radio set is assembled properly and ready for operation. Also check that all the accessories are properly connected. 2. In static  installations,  replace  or  recharge  the  battery.  The  first  time  a  new  battery is  used,  it should be charged for at least 16 hours. 3. Check the antenna system and  its connections. In  particular, for whip antennas check that the whip is screwed on properly, with its base flush against the top of the antenna base or matching unit. 4. Pay  attention  to  any  fault  messages  that  may  appear  on  the  Micom-Z  display,  either  upon power-up or during operation, and refer to para.  3-7.2.2 for instructions. If the  problem persists, identify the closest description appearing in Table  3-1 and  then perform the listed corrective actions until the problem disappears. If problem persists, refer to para.  3-7.2.3.
OM-E 2072-09689-00 3-15 Table  3-1. Preliminary Troubleshooting Chart Problem  Corrective Actions Blank display  Check that the DC power cable is properly connected to the radio set and to the battery. Check the 30A fuse installed in the fuse holder located on the red wire of the DC power cable Display present, but weak or no receive signal or noise Check for proper connection of antenna to its antenna tuner, and from the antenna tuner to radio (loose or broken connections, damage to cables, etc.). Change the operating channel, and then return to the original channel. This will cause the antenna tuner to retune.  Check for correct programming of operating channel (frequency, mode of operation, etc.). You may also try to establish communication with a nearby station, to check whether you can receive it properly. Set the squelch to OFF Engine noise picked up by the antenna Determine by observing difference in the reception by turning the engine ON/OFF. After confirming that the engine noise is the source, make sure that the ground leads are properly connected, and all power wires and ground leads are as short as possible. Install a noise reduction kit No transmission, or low transmit power Check that grounding leads are properly connected from the radio and from the antenna tuner to the vehicle chassis, and they are as short as possible.. While speaking, check the transmit power indicator for activity: •  If  the  transmit  power  indication  is  low,  this  may  be  caused  by  a  faulty microphone, faulty transmitter, overheating, or a defective antenna system. • If there is a problem with the antenna system, often you may note that the reflected  power  indication  is  very  large.  Even  if  the  reflected  power indication  seems  normal,  try  to  change  the  operating  channel,  and  then return to the original channel  (this will cause the antenna tuner to retune). Also  check  the  antenna  system,  the  connections  of  the  antenna  to  the antenna tuner,  and the connections from the antenna tuner to radio (loose or broken connections, damage to cables, etc.)   3-7.2.2  Handling Fault Messages In case a failure occurs during operation, the radio displays a fault message. Refer to Table  3-2 and perform the corrective actions listed for the corresponding message, until the problem is corrected. Table  3-2. Fault Messages Message  Corrective Actions NO CLOCK   Service the Micom-Z unit (defective LORD board) SYN FAIL  Perform the built-in test using the MRC, to obtain more information PW_LATCH  Perform the built-in test using the MRC, to obtain more information.  Check the condition of the antenna and its connections, because this error is displayed when the VSWR exceeds 3.5:1. To check whether the problem is caused by high VSWR, transmit into a dummy load with suitable power rating. If the problem persists, service the Micom-Z unit (defective HIGH POWER board)
OM-E 2072-09689-00 3-16 Table  3-2. Fault Messages (Cont’d)  Message  Corrective Actions OVER TMP   Check that there is no obstruction to free air flow around the radio.  When using the cooling tray, check that the fan is working and there are no obstructions to fan rotation. Perform the built-in test using the MRC, to obtain more information. If no further information is displayed, service the Micom-Z unit (defective HIGH POWER board) CU-LIMIT   Check that the radio is programmed to TUNER OFF when it is not equipped with an ATU, or does not use the FAD1410 antenna system. Check for short-circuit or other damage to the antenna feed coax. Check that the ATU is in good working condition NOT PROG (Error 14)  This message indicates that the radio is not programmed (the message may also appear if the radio DC power failed during programming). In this case, the default baud rate of the MRC interface is 1200 bps. Program the radio parameters (using the MRC). This forces the radio to accept the downloaded parameters  BATTERY FAIL (Error 11) Micom-Z has an internal battery, that enables the memory to store the last channel information that was used before the radio was turned off. If this battery becomes weak, it will display this warning. When the battery is dead, all the channel information will be retained, but the radio will always use channel 1 when you turn the radio on. (Example: if you are scanning in the ALE mode and you turn the radio off; when you turn the radio back on, it will be on channel 1). You may continue using the radio, but request service as soon as possible DATABASE FAIL (Error 15) This message will appear if the ALE scanned channels do not match the programmed channels in the MRC (for example, ALE is programmed to scan channels 1, 2 and 3, but the MRC program does not have a frequency programmed into channel 3).  Check and correct the programmed parameters   3-7.2.3  Interpreting BIT Results and Error Codes Micom-Z performs self-test whenever it is turned on, and also upon operator’s command, as explained below.  If a problem is detected, you will see a two-digit error code. Most of the codes indicate a hardware problem, and therefore, in general, you should request service for Micom-Z unit (contact your service representative and report the malfunction or error code). 1. Turn the radio set off, and then turn it back on, and monitor the display: every time the radio is turned  on,  a  self-test  procedure  is  performed.  If  an  internal  malfunction  is  found,  an  error message  will  be  displayed.  Refer  to  Table   3-3  for  a  description  of  the  error  codes,  and  the recommended actions. 2. Activate the BIT function, using MENU > BIT. You have three options: • FULL (F1) – runs a full test of the Micom-Z. • CHAN (F2) – tests Micom-Z operation on the current channel.  • L.RF (F3)  – tests the Micom-Z receive path only.
OM-E 2072-09689-00 3-17 NOTE To  obtain  reliable  results,  it  is  necessary  to  perform  the  test  under controlled  conditions.  This  is  achieved  by  disconnecting  the  external antenna, and connecting a 50Ω dummy load or 30 dB attenuator with a suitable power rating (150W or more) to the ANT connector (make sure to select TUNE on PROG > RAD > OPTS > ACC when using a dummy load). In addition, you must perform the test in the SSB mode, and  the  DPWR  parameter  must  be  MAX  (DPWR  changes  only  after the Micom-Z is turned off and then back on). Select  the  test  best  suited  to  the  detected  problem,  and  wait  a  few  seconds  for  the  test  to complete.  Refer to Table  3-3  for  a  description  of the test result  codes,  and the recommended actions. Table  3-3.

OM-E 2072-09689-00 4-1 CHAPTER 4   USING THE PROGRAMMING MODE 4-1.  SCOPE This Chapter provides concise instructions for using the PROG mode. The  Programming  mode,  accessed  by  opening  the  PROG  menu  is  used  to  program  manually  the parameters needed by your radio set. There are three main group of parameters: • Radio parameters – the parameters for communication in your environment and in the radio nets you use most of the time. Refer to para.  4-3 for details. • ALE parameters – the parameters needed to use the ALE function. Refer to para.  4-4 for details. • CCIR  parameters  –  the  parameters  needed  to  use  the  CCIR  function.  Refer  to  para.   4-5  for details. The  manufacturer  offers  a  dedicated  Radio  Service  Software  (MRC),  which  is  an  efficient  tool  for preparing sets of operational parameters for Micom-Z radio. MRC supports all the functions that can be performed by means of the PROG menu. MRC is recommended when it is necessary to configure many radio sets. Micom-Z lets you change the most of parameters in use on-line, to adjust to any particular situation. However,  when  you  select  another  channel  or  net,  the  changes  are  discarded  and  the  programmed values are used again.
OM-E 2072-09689-00 4-2 4-2.  THE PROG MENU NOTE The  PROG  menu  is  accessible  only if  the radio  is not  locked.

OM-E 2072-09689-00 4-5 4-3.1  Programming Channels  The Channel programming menu includes two groups of options: • GET and STOR are used to copy the channel parameters from one selected channel to another, and ERAS is used to delete the user-configured parameters of a selected channel. • The  other  options  are  used  to  configure  the  operational  parameters  to  be  used  on  the  channel being configured. To enter the Channel Programming mode: 1. Enter the Radio Programming menu. 2. Press CHAN. The CHAN menu provides the following options (see also Figure  4-1):  Option  Description GET   GET retrieves all the parameters defined for a channel already programmed in Micom-Z (the default is the current channel, but you can select any other channel).  You can store these parameters in a new channel using the STOR function, and then edit the parameters as required. STOR  Store the set of parameters in a selected channel. ERAS   ERAS is used to delete (erase) a channel. Actually, this action only replaces the user-modified parameters of the channel with the factory-default parameters, but marks the channel as not programmed. The factory-default parameter values are as follows: •  Rx Frequency  15.000.00 MHz •  Tx Frequency  15.000.00 MHz •  SSB Mode   USB •  Bandwidth  2.7 •  Tx Power  MAX •  AGC  SLOW. PWR Select the channel transmit power level. Four transmit power levels can be selected:  • LOW – 25 W nominal • MED – 60 W nominal  • HIGH – 100 W nominal  • MAX – 125 W nominal. FREQ  Select the channel frequency. Micom-Z offers four frequency options:  • SMPX  Simplex Frequency – the same frequency is used for both transmission and reception.  • DPLX  Duplex Frequency – transmits on one frequency and receives on a different frequency.  • RXO  Receiving Only Frequency – defines a frequency for reception only. Transmission on that frequency is disabled. The available frequency range is 100 kHz to 30 MHz.  • TXO  Transmitting Only Frequency – defines a frequency for transmission only. You cannot receive on that frequency. The available frequency range is 1.6 to 30 MHz. BAND   Select the channel operating sideband:  • USB – upper sideband mode • LSB – lower sideband mode.
OM-E 2072-09689-00 4-6 Option  Description MODE   Select the channel radio operating mode:  • SSB – single sideband  • AME – amplitude modulation equivalent  • PLT – single sideband with pilot signal. AGC   Select the channel Automatic Gain Control mode. Micom-Z offers two AGC response speeds: SLOW and FAST. You can also turn the AGC OFF completely. BW  Selects the filter bandwidth.  • HS – high sensitivity filter (450 to 1500 Hz) for best voice communication under marginal conditions • 2.7 – 300 to 2700 Hz • 3.0 – 300 to 3000 Hz • 3.3 – 300 to 3300 Hz. Always select this bandwidth for data transmission  • LSM – bandwidth optimized for use with low speed modems (1450 to 1950 Hz) • CW (Continuous Wave or Morse operation). The bandwidth used in this case is selected by MENU > PROG > RAD > PRMT > CW.  4-3.2  Configuring Radio Parameters  The radio parameters are global parameters, which are used for all the channels. To start the radio parameters programming: 1. Enter the Radio Programming menu. 2. Press PRMT. The PRMT option in the Radio Programming menu provides the following options (see Figure  4-1):  Option  Description BAUD  Selects the data transmission rate of the internal modem: • 1.2 – 1200 bps  • 2.4 – 2400 bps  • 4.8 – 4800 bps  • 9.6 – 9600 bps. DPWR  Selects the maximum transmit power for data transmission, that is, for a transmission initiated by the data PTT. The available selections are: • LOW – 25 W nominal • MED – 60 W nominal • HIGH – 100 W nominal  • MAX – 125 W nominal. The transmit power used in the other modes is independently selected for each channel. If the selected data transmit power exceeds the transmit power configured on the operating channel, the radio will use the lower channel transmit power.  When operating the radio without the optional cooling tray, it is recommended to use the lower power settings (LOW or MED). MST   Enables/disables the sidetone heard in the speaker when you transmit using the microphone. AST   Enables/disables the heard in the speaker sidetone when you transmit using an accessory connected through the rear panel.
OM-E 2072-09689-00 4-7 Option  Description PTBP   Enables/disables the transmission of a beep when the local push-to-talk (PTT) button is released. This beep is used to notify the other stations that the local (your) radio set has stopped transmitting and returned to the receive mode: therefore, another radio can start transmitting.  KBBP   Enables/disables the keypad beep. When enabled, a beep is heard whenever a valid key is pressed. TONE   Select the keypad beep level: high or low. The selection is relevant only when the keypad beep is enabled. ADT   Selects the alternate display time-out, that is, the time after which a keypad sequence is automatically aborted in case no action is taken. In this case, the display returns to the previous screen. The time-out interval can be selected in the range of 1 to 10 seconds.  ATTN   Enables/disables the use of an internal RF attenuator. The attenuator is used to reduce interference when your radio is located near strong transmitters. CW   Select the channel filter bandwidth used in the CW mode:  • 0.25 – 250 Hz • 0.5 – 500 Hz • 0.8 – 800 Hz A lower value improves the reception but requires better frequency accuracy. RCLV  Enables/disables the receive signal level display. If the receive signal indication is not enabled, you can temporarily enable it using one of the function keys. DIM  Enables/disables automatic dimming of the display.  Usually, the display operates continuously. However, you can program the display to be normally off, and be automatically turned on when the transceiver detects any type of activity (keypad, PTT, incoming call, etc.). The ADT option selects the time before the display is again turned off when inactive. RTSC  Controls the way scanning is resumed while operating in the CCIR mode: •  YES – scanning is automatically resumed after an idle time of 2 minutes. •  NO – the operator must manually resume scanning.  4-3.3  Setting Radio Options  To start programming the radio options: 1. Enter the Radio Programming menu. 2. Press OPTS. The OPTS option in the Radio Programming menu provides two sets of options (see Figure  4-1):  •••• ACC  Used to configure the radio for operation with an antenna tuner:  NONE Operation without antenna tuner, possible only when using a broadband antenna.  TUNE Operation with an external antenna tuner. An antenna tuner is always necessary when using a whip. To use an external antenna tuner, select this option.  •••• SLCL Used to select the radio link setup mode:  ALE Use of ALE protocol.  CCIR  Use of CCIR protocol.  NONE No link set up protocol, i.e., you can set up groups of channels to be scanned.   After selecting the desired mode, select SET to set the new mode.

The configuration includes the following menus: •••• NAME  Edit the net name and the self-address: • NET: Define or edit the net names.  It is not allowed to use a name already used as a self-address, nor an address already appearing in the address directory. • SELF: Define or edit your self address (the identification of your station, to be used by other stations within the same net).  It is not allowed to use a name already used as a net address, nor an address already appearing in the address directory.  A net name or self address can contain up to 15 characters. Valid characters are the letters A to Z and the numerals 0 to 9.  •••• MEMB  Add  or  erase  members  (station  addresses)  from  the  list  of  net  members.  This  list defines  which  stations  can  participate  in  a  net  call  (a  net  can  have  up  to  16 addresses).  The MEMB menu also enables you to sort the list of members: this determines the order in which members respond to a net call. You can arrange the order of the list of members manually, or instruct the radio to arrange them in alphanumeric order. A  member  name  can  contain  up  to  15  characters.  Valid  characters  are  the  letters A to Z and the numerals 0 to 9. It is not allowed to define a name already used as a net address, nor an address already appearing in the address directory. New member names will automatically be added to the directory list (unless the directory is full).
OM-E 2072-09689-00 4-11 •••• CHAN  Add or remove channels to the list of scanned channels in a net, and to define the channel on which AllCalls are to be transmitted (the AllCall channel (ALLC)). NOTES •  Each net can contain up to 100 scanned channels. •  All nets combined can contain up to  100 scanned channels. If you exceed  this  number,  the  message  OVER  100  CH  is  displayed  for one second, and then the display returns to the previous menu. •  If  you  enter  a  channel  which  is  not  programmed,  a  NOT  PROG message  is  displayed  for  a second,  and  the display  returns to the previous menu. •••• OPT  Configure net options, including: sounding, silent net, LQA request, scan rate, home acknowledgment,  monitor  acknowledgment,  occupancy  detection,  master/slave definitions, AllCall options and tune time.  •••• GET  Copy  all  parameters  from  one  net  to  another.  This  function  is  useful  if  you  are defining a new net and wish to base most of its parameters on an existing net, for instance  if  you  need  to  use  different  frequencies/channels  for  day  and  night communication,  but  all  other  net  information  (such  as  stations  and  names)  is identical. •••• ERAS  Erase an entire net from the ALE data base.  After preparing a set of parameters, your entries are checked and any errors are reported. If you do not correct the detected errors, Micom-Z will offer to discard the new set of parameters. 4-4.1.2  Default Values Unless you define different values, each net uses the following factory-defaults: • Net Name    No default defined • Self Address    No default defined • AllCall    Send and receive enabled • AllCall Channel    No default defined • Tune Time    No tune time • Silent    No • Home Acknowledgment    Yes • Monitor Acknowledgment   No • Master/Slave    Master • LQA Request    Yes • Sounding    Manual • Occupancy Check    No • Scanned Channels    No default defined.  When  programming  a  new  net  or  other  ALE  parameters,  you  do  not  need  to  define  all  parameters: change only those for which the default values are not suitable.
OM-E 2072-09689-00 4-12 4-4.2  Setting the Net Options Use this menu to configure net options: •••• SOND   Sounding Parameters: define the interval (in minutes) at which automatic sounding is performed (30, 60, 90 or 120 minutes), or define sounding as a manual function. See Appendix A for a detailed explanation on the sounding process. •••• SLNT   Silent Mode: select whether the net is in the silent mode, which means that members in the net can initiate calls but not allowed to respond to an ALE transmission. •••• LQAR   LQA Reports: select whether your radio will ask the called station for a report on the quality of the communication every time a call is initiated. •••• SCN   Scan Rate: select the number of channels scanned each second when the radio is in ALE mode: can be set to 2 or 5 channels per second. •••• HACK  Home Acknowledgment: enable/disable home acknowledgment. When enabled, the radio transmits an end-of-call indication to the remote station. •••• MACK  Monitor Acknowledgment: enable/disable monitor acknowledgment. When enabled, the radio transmits an accept call indication to the station that initiated the call. •••• OCUP   Occupancy  Check:  enable/disable  the  occupancy  check.  The  occupancy  check defines whether the radio uses the speech detect mechanism to determine whether a channel on which a call is about to be made is occupied. If this option is ON, a call cannot  be  initiated  on  a  channel  determined  to  be  occupied.  This  option  can  be operated in addition to the ALE signal detection mechanism. You can select the interval at which occupancy checks are made (300 to 3000 msec, in 300-msec increments). •••• M/S   Master/Slave:  select whether  your radio serves as a master  or  slave  in the current ALE network. Only a master station can initiate a Net Call. •••• ALLC   AllCall Settings: this option determines whether the ALE is able to receive and/or send AllCalls. An AllCall is an ALE broadcast transmission. All stations receiving an AllCall are linked  to  the  sender,  even  if  they  do  not  recognize  the  sender’s  address.  If  no AllCall channel is defined, the call will be made on the best channel in the net. •••• TUNE   Tune  Time:  select  the  tuning  time. Tuning  time  is  the  maximum  time  the  current ALE waits for the called station to tune (this is the tune-in time of the slowest tuner in the net). The tune time is added to the calculated response time. Tune time can be 1 to 20 seconds, or OFF (zero). 4-4.3  Directory Parameters This  DIR  option  on  the  ALE  Programming  menu  enables  preparing  the  ALE  address  list.  This  list contains the names of stations to which the radio can address a private call using the ALE. You can add a new address, and edit an existing address. A name can contain up to 15 characters. Valid characters are the letters A to Z and the numerals 0 to 9. You cannot add an address which is identical to the name of a programmed net, nor an address already used  as  a  self  address  in  a  programmed  net.  The  list  can  contain  up  to  100  addresses,  and  is automatically sorted in ascending alphanumeric order. 4-4.4  AMD Message Configuration The AMD option of the ALE Programming menu is used to view, edit, add or erase messages intended for transmission. The characters you can enter in messages using the radio keypad are: A to Z, 0 to 9, space, * and #. See message preparation details in Chapter 2.  Messages  programmed  using  a  remote  PC  with  a  standard  keyboard  can  contain  all  the  ASCII characters the range of 20 (hexa) to 5F (hexa).
OM-E 2072-09689-00 4-13 The message list can contain up to 12 messages, numbered AMD 0 to AMD 11. Each  message can contain up to 90 characters. NOTE If no messages are stored, EMPTY will appear in the second display line. 4-4.5  ALE Options Configuration This menu enables you to configure the following ALE options: Option  Description PTOT   PTT Timeout: the time (in minutes) which elapses between the moment you release the PTT button, until the ALE disconnects the link. The allowed range is 1 to 10 minutes. EXAL   External Alarm: activate/deactivate the radio external alarm when a call is received. ALRT   Alert tone: enable/disable the generation of an alert tone whenever a link is established. TOT   Accept Link Time-out Time: the radio can be configured to disconnect the link automatically if neither the PTT, nor any other key is pressed within 30 seconds from the reception of a call. If Accept Link TOT is set to NO, the received call is accepted immediately and automatically. MLQA   Minimum LQA Score: determines the minimum acceptable LQA (Link Quality Analysis) score allowed when trying to establish a link on a specific channel.  If the minimum score is not achieved when the radio attempts to establish a link in the ALE mode, the radio will try to establish a link on the scanned channel with the next best LQA score. At the end of this process, a link will be established on the scan channel with the best LQA score. If the call is made on a specific channel, the radio ignores the minimum LQA score check. The allowed range of LQA scores is 0 to 100%. When selecting the minimum LQA score, remember that in accordance with the ALE standards, the maximum LQA score (assigned for receiving an optimum sounding is 70%), and the minimum score is 30%. The score given to a station that did not send any sounding or a station whose sounding has not been received is also 30%. QCAL  Quick Call: enable/disable initiating a call to the last called address by pressing the MIC PTT button twice in rapid sequence (double pressing). AADR  Automatic address: enable/disable automatically adding the source addresses of incoming calls to the ALE directory. NOTE If the directory is full, new addresses will not be added.  MxCH  Maximum Scan Channels: this parameter is used to adapt the duration of the calling signal to the total number of scanned NET, to ensure that communications are not disrupted. You can select between automatic selection, or select a value in the range of 0 to 59 seconds.  ANY  AnyCall: enable/disable the sending AnyCalls. WILD  Wildcard: enable/disable the sending wildcard calls. AMD  Automatic Message Display: enable/disable the sending AMD messages. ILNK  Inlink: enable/disable the inlink facility, which enables notifying other call participants when each participant disconnects from the link. All participants must be programmed to use the same selection (either YES or NO). Do not enable the inlink function when communicating with a radio that does not support the full ALE capabilities in accordance with MIL-STD-188-141B.
OM-E 2072-09689-00 4-14 Option  Description BDLK  Bidirectional link: enable/disable automatically setting up a link on the best channel after a bidirectional handshake with an individual station.  The ALE options have the following factory-default values: • PTT Timeout  No timeout •••• Alert Yes • External Alarm   Yes • Auto Address   No • Quick Call   Yes • Minimum LQA score   0 • Accept Link Timeout   Yes • MxCH  Auto • ANY  Yes • WILD  Yes • AMD  Yes • ILNK  No • BDLK   No When configuring ALE options, you do not need to define all parameters: change only those for which the factory-default values are not suitable. 4-4.6  Auto Dial Parameters Auto  Dial  enables  you  to  set  shortcuts  for  calls  to  frequently  called  stations,  with  or  without automatically attaching messages when a station is called:  •••• AUTO  Used to configure up to 10 autodial codes, numbered AUTO 0 to AUTO 9. •••• AMD  Used to prepare AMD messages for sending when an autodial code is used. See message preparation details in Chapter 2.  NOTE If  a  message  is  attached  to  the  address,  an  exclamation  mark precedes the address.
OM-E 2072-09689-00 4-15 4-4.7  Storing ALE parameters Before exiting the ALE programming menu, you must store the parameters you have programmed. NOTE If you press the MENU or ESC key to exit programming mode without first  saving  your  changes,  you  will  be  prompted  to  store  the  ALE configuration changes. Press YES to store the configuration. If  you  press  NO,  the  configuration  will  revert  to  the  previous configuration,  and  any  changes  made  in  the  ALE  programming session will be ignored. 4-4.8  Using the New Station Address Filter To help you add new station addresses to the ALE directory of your radio set in a controlled manner, Micom-Z has a special ALE address filter. To enable this filter, enable the Auto Address function on the PROG > ALE > OPT > AADR menu (this function can also be enabled by means of the MRC). When enabled, the address filter compares the source address of each call received by your radio set with  the  addresses  stored  in  the  ALE  directory.  When  the  first  new  unlisted  address  is  found,  it  is stored  in  a  special  memory  stack,  and  you  are  notified  that  at  least  one  unlisted  address  has  been detected by adding the option RCV under PROG > ALE, after the NET option. When you want to check the addresses stored in the stack, you select RCV and then decide whether to erase an address or add it to the ALE directory of your radio set.  Up to 20 new addresses can be stored in this stack, which is organized as a FIFO stack: this means that when  a  new  address,  different  from  all  the  previously  detected  addresses,  is  received  while  20 addresses are already stored, it will replace the oldest address.  The information on the received addresses is automatically erased when the radio is turned off; only addresses added to the directory remain in the directory. To edit the received addresses and add addresses to the ALE directory: 1. Press MENU and select ALE.  2. When addresses are stored in the new received addresses stack, you will see the RCV option. Press RCV to display the RCV screen. 3. The  RCV  screen  displays  the  last  detected  unlisted  address.  Use  the  UP/DOWN  arrows  to display the desired address (the display is cyclical). 4. When  the  desired  address  is  displayed,  press  the  key  corresponding  to  the  action  to  be performed: • To delete the address from the stack, press ERAS. • To add the address to the directory, press ADD. The address is removed from the stack. 5. To confirm, press SAVE. 6. Repeat the actions until all the desired addresses are processed. When done, press ESC to end. If the stack is now empty, the RCV option is no longer displayed on the ALE menu.

CONFIGURING CCIR SELF-ADDRESSES 4-6.1  CCIR Addressing Plan CCIR uses selective calling: any station operating on the same channel, or scanning channels in the same (or partially overlapping) group of channels, will accept a call only if it is directed to it, or to the set of stations matching the destination specified by the transmitting station. The  current CCIR addressing  plan  supports six-digit  addresses, that is, 000000 to  999999. Previous CCIR standards specified only four-digit addresses, that is, 0000 to 9999, and therefore, for backward compatibility,  Micom-Z  supports  both  addressing  plans.  This  means  that  you  can  program  two independent self-addresses for your radio set, a four-digit self-address and a six-digit self-address, and the radio will respond to calls using either address.
OM-E 2072-09689-00 4-18 In addition to individual station addressses, the CCIR addressing plan specifies the following types of destination addresses (see Table  4-1 and Table  4-2): • Sub-Group Addresses – addresses ending with a single 0 are directed to a set of stations called sub-group.  When  using four-digit  addresses,  the  first  three  digits of  the  address determine  the sub-group  address,  whereas  when  using  six-digit  addresses,  the  first  five  digits  of  the  address determine the sub-group address.  For  example,  a  transceiver  with  self-address  1234  is  included  in  sub-group  1230,  and  it  will accept all calls with address 1230.  • Group Addresses – addresses ending in two consecutive 0 are directed to a set of stations called group. When using four-digit addresses, the first two digits of the address determine the group address, whereas when using six-digit addresses, the first four digits of the address determine the group address.  For example, a transceiver with self-address 1234 is included in group 1200, and it will accept all calls with address 1200.  • All Addresses – addresses ending with in three consecutive 0 are called the all address. When using four-digit addresses, all the stations with the same first digit will accept the all call; when using six-digit addresses, all the stations with the same three digits will accept the all call. •••• Beacon Address  – a beacon call is identified by its last two digits, which are 99. Figure  4-4 and Figure  4-5 illustrate the concept of groups and sub-groups for the two CCIR addressing plans. As a result, when assigning self-addresses to an individual station, never select addresses ending in  one  or  more  0,  nor  addresses  ending  in  99.  Such  addresses  are  allowed  only  as  destination addresses. Table  4-1. Four-Digit CCIR Addressing Plan Address Type  Description Sub-Group  A call transmitted to XXX0 is received by up to 9 transceivers with individual addresses in the range of XXX1 to XXX9. Group  A call transmitted to XX00 is received by up to 89 transceivers with individual addresses in the range of XX01 to XX99. All  A call transmitted to X000 is received by up to 890 transceivers with individual addresses in the range of X001 to X999. Beacon   A call transmitted to XX99 is interpreted as a beacon call  Table  4-2. Six-Digit CCIR Addressing Plan Address Type  Description Sub-Group  A call transmitted to XXXXX0 is received by up to 9 transceivers with individual addresses in the range of XXXXX1 to XXXXX9. Group  A call transmitted to XXXX00 is received by up to 89 transceivers with individual addresses in the range of XXXX01 to XXXX99. All  A call transmitted to XXX000 is received by up to 890 transceivers with individual addresses in the range of XXX001 to XXX999. Beacon  A call transmitted to XXXX99 is interpreted as a beacon call

OM-E 2072-09689-00 4-20 4-6.2  Configuring the Self-Address  NOTE A  call  transmitted  to  XXX0,  XX00,  or  X000  is  received  by  multiple transceivers. Therefore, do not configure a self-address with “0”, “00”, or “000” as the last digits.  In  addition,  a  call  transmitted  to  XX99  acts  as  a  beacon  call. Therefore, do not configure a self-address with “99” as the last digits.  To configure four-digit self-addresses: 1. Access the CCIR Programming menu: MENU > MORE > PROG > CCIR.  2. Press SELF to access your self-address.  3. Press UP/DOWN keys to scroll to SELF4.  4. Enter the prescribed four-digit self-address. If you enter a self-address with less than four digits, the transceiver automatically converts it to a four-digit self-address. For example, if you enter “1”, then the transceiver automatically converts it to “0001”. 5. Press SAVE to confirm.  6. Press MENU to exit.  7. Press YES to store. To configure six-digit self-addresses: 1. Access the CCIR Programming menu: MENU > MORE > PROG > CCIR.  2. Press SELF to access your self-address.  3. Press UP/DOWN keys to scroll to SELF6. If you enter a self-address with less than six digits, the  transceiver  automatically  converts  it  to  a  six-digit  self-address.  For  example,  if  you  enter “1”, then the transceiver automatically converts it to “000001”.  4. Enter your six-digit self-address.  5. Press SAVE to confirm. 6. Press MENU to exit.  7. Press YES to store.

OM-E 2072-09689-00 A-1 APPENDIX A  ALE CAPABILITIES AND FEATURES  A-1.  SCOPE This Appendix provides a concise description of the ALE capabilities and features. A-2.  SCANNING The method used to select the best channel is based on scanning: as long as it is idle, a radio operating in the ALE mode switches frequency at a relatively rapid rate (programmable at 2 or 5 channels per second)  within  the  group  of  channels  that  can  be  used  (the  ALE  frequency  table,  with  up  to  100 frequencies). During this process, it collects information regarding the state of each channel (busy/free and its background noise) that can be used together with the quality information collected by sounding when the user initiates a call. • When a station initiates a  call, it selects the best  free channel  on the  basis of  the most  recent information, switches to that channel and then transmits a call request for a time sufficient for any station to finish scanning all the preprogrammed channels and reach the selected channel.  • Any  station  that  should  receive  this  call  will  then  stop  on  the  channel  used  by  the  initiating station,  and  will  use  the  channel  for  communication.  The  exact  response  to  the  call  request depends on the type of call (call types are described below): as a result, it is possible to program any desired station to ignore some types of calls (in fact, any call not specifically addressed to it). A-3.  SOUNDING Automatic sounding is  the method used by ALE for testing the quality of  channels and propagation paths  under  field  conditions.  The  sounding  signal  is  a  unilateral  identifying  broadcast,  repeated  at periodic  intervals  on  unoccupied  channels.  Identification  of  a  sounding  signal  sent  from  a  station indicates a high probability of bidirectional communication. The  length  of  the  sounding  cycles  can  be  set  to  short  or  long  cycles,  depending  on  propagation conditions. When propagation changes are slow, long intervals of about 1 or 2 hours may be sufficient. If,  however,  the  propagation  changes  are  erratic  and  rapidly  changing,  or  if  it  is  critical  to  have updated  connectivity  information,  then  shorter  intervals  are  recommended.  Each  station  can  also measure BER and S/N, and update the LQA table accordingly. The  maximum  score  for  receiving  an  optimum  sounding  is  70%;  the  minimum  score  is  30%.  The score  given  to  a  station  that  did  not  send  any  sounding  or  a  station  whose  sounding  has  not  been received is also 30%. A-3.1  Sounding Cycle Time The  sounding signal is  repeated  at  regular intervals  on  all  the channels in the network. A complete round of sounding messages, or sounding  cycle, can be programmed to 30,  60,  90, or 120  minutes when the automatic sounding is on. You can also manually initiate sounding when there is a specific need for it, even if the system is set to operate in the automatic mode.  A short sounding cycle ensures a more updated LQA memory. However, frequent sounding increases network  occupancy,  leaving  less  channel-free  time  for  the  users.  Figure   A-1  illustrates  network occupancy in relation to sounding  cycles of 30,  60,  90  and 120 minutes.  (Note that  both axes have logarithmic scales.) The chart also shows 80% and 95% occupancy in a 120-minute sounding cycle at a very rapid scanning rate (applicable only to multiple-channel networks).

Network Occupancy Use  the  chart  to  determine  the  best  sounding  cycle  for  your  particular  network,  bearing  in  mind network occupancy, propagation conditions and other considerations. The following examples demonstrate how to read the chart.  • In a network of nine channels used by eight members, a 30-minute sounding cycle would result in 80% occupancy; a 60-minute cycle would result in 40% occupancy; a 90-minute cycle would result in 27% occupancy and a 120-minute cycle would result in 20% occupancy.  • If there are only two or three channels in the network, a sounding cycle of 30 minutes allows enough channel-free time, even for as many as ten users. Under field conditions, occupancy will usually be less than the value obtained from the chart because not every station receives all the soundings that are being broadcast on all channels. To increase channel-free time for the users by reducing network occupancy, you can try one of these four methods (in this order): 1. Increase the sounding cycle time (to 90 or 120 minutes). 2. Reduce the number of channels in the network (for example, by using different nets for different times of day). 3. Reduce the number of stations in the network by re-arranging the hierarchical subgrouping of stations. 4. Request all stations to set the fast scan rate option. A-3.2  Manual Sounding When it is necessary to perform a rapid sounding cycle on all channels instead of, or in addition to the automatic sounding cycle, manual sounding can be used.
OM-E 2072-09689-00 A-3 A-4.  LQA MEMORY The  ALE  builds  a  database  of  connectivity  information  based  on  calls  and  the  ALE  sounding messages  transmitted  by other stations  in  the  network.  This  information  is  stored  in  a  special  LQA memory and is used to determine the link quality of all channels in the networks. The data in the LQA memory is time-weighted, that is, recent information is given more value than old, thus compensating for changing propagation conditions. A-5.  BIDIRECTIONAL HANDSHAKE The  bidirectional  handshake  is  an  operator-initiated  procedure  used  to  exchange  LQA  scores  with other stations without establishing a link.  NOTE The Micom-Z can also be programmed to automatically initiate the call to  the  station  after  finishing  the  bidirectional  handshake  (using  the BDLK parameter reached under the ALE programming options). This procedure is useful in the following cases: • The radio has only recently been switched on and the automatic sounding cycle has not yet been completed. • The  operator  wishes  to  update  the  LQA  scores  before  initiating  a  call  to  another  station,  for example, for example, because of abrupt atmospheric charges, or other propagation changes. • A new or passive station has joined the system. A bidirectional handshake can be carried out with a single station or with all stations in the net. It can be carried out either on a single channel, or on all the net channels. When required, a message can also be added to the procedure. After  a bidirectional handshake  with  a  single station, the  LQA  matrices of both radios are  updated. The operator can then initiate a call to that station and obtain the best channel automatically. When the bidirectional handshake procedure is performed with a net, all the stations in the net update their LQA tables.
OM-E 2072-09689-00 A-4 A-6.  SELECTIVE CALLING Micom-Z uses an  approach standardized in MIL-STD-181-141B and  FED-1075 to selective calling, and  therefore  has  the  capability  and  flexibility  to  link  with  one  or  many  prearranged  or  as-needed single or multiple stations.  This selective calling capability is based on the use of a special addressing method. A-6.1  ALE Addressing Method ALE uses digital addresses to identify stations. The fundamental address element in the ALE system is the single word: one ALE address word must always contain three characters (one triplet).  A single ALE word is needed for the basic individual station address (this is called a basic address). To increase the available range of addresses, basic addresses can be expanded up to a maximum of 5 words (15 characters): such addresses are called extended addresses.  The characters that can used in addresses are a subset of the standard Basic 38 ASCII character set. This subset includes: • All the capital (upper case) letters (A to Z) • All the digits (0 to 9) • Two utility characters:   The stuffing symbol @. It can be used to add characters at the end of an address, so that the resulting length is  a whole number of words (triplets). A  receiving station then interprets only the non-stuffing characters. For example, if the address has 8 characters, add one @ at the end of the address, whereas for an address with 7 characters, two @ symbols must be added. In special addressing modes, this symbol is interpreted as an ignore instruction: see additional utilization guidelines in Table  A-1.  The wildcard symbol ?.  It is  used to indicate that any character (except @) is acceptable (this is the equivalent of a don’t mind instruction). See Table  A-2 for utilization guidelines in the special addressing modes. NOTE In  the  following  sections,  “A,”  “B,”  “C”  or  “D”  indicates  any alphanumeric character other than “@” or “?”.  Micom-Z has the capacity to store and use 100 addresses of up to 15 characters each. Micom-Z will reject addresses longer than 15 characters, and will notify you with an UFA WRONG message.  A-6.2  Address and Call Types ALE  stations,  including  the  Micom-Z,  have  the  capability  and  flexibility  to  link  with  one  or  many prearranged or as-needed single or multiple stations. There are three general addressing methods:  • Individual station addressing • Multiple stations addressing, for example, net and group • Special addressing modes, for example, AllCall, AnyCall, etc.  The following sections explain the addressing modes and how they can be used for various purposes. A-6.2.1  Individual Station Address The individual station address may contain 1, 2, 3, 4, or 5 words. To enable using addresses that are not an integer multiple of 3 characters (for example, an address consisting of  1, 2, 7,  8, 10, …, etc. characters),  stuffing  can  be  used:  with  stuffing,  the  last  address  word  includes  one  or  two  stuffing symbols in the last position(s) (see the “stuff-1” and “stuff-2” patterns in Table  A-1).  The wildcard symbol cannot be included in an individual station address, nor in a  call request to an individual station.
OM-E 2072-09689-00 A-5 Table  A-1. Use of “@” Stuffing Symbol Pattern  Interpretation A B C “Standard” 3-character address word, shown here for reference. Only the station with this address stops scanning and responds A B @  “Stuff-1” reduced address field, used to add characters “A, B” at the end of the address A @ @ “Stuff-2” reduced address field, used to add character “A” at the end of the address @ ? @ “AllCall” global address (see also Table  A-2): all the stations stop and listen (unless this function is inhibited)  @ A @  “Selective AllCall” global address: each station with the same last character “A” stop scanning and listen (unless this function is inhibited @ @ ? “AnyCall” global address (see also Table  A-2): all the stations stop scanning and respond in randomly selected timeslots (unless this function is inhibited) @ @ A @ B@ (option) “Selective AnyCall” address: each station with same last character(s) “A” (or “B”) stops scanning and responds in a randomly selected timeslot (unless this function is inhibited), using its own address @ A B @ C D (option) “Double selective AnyCall” address: each station with same last characters “AB” (or “CD”) stops scanning and responds in a randomly selected timeslot (unless this function is inhibited), using its own address @ @ @ “Null” address; all the stations ignore this address. The null address intended for use in test and maintenance, or to create an extra “buffer” timeslot  A-6.2.2  Net Addresses The purpose of a net call is to rapidly and efficiently establish contact with multiple prearranged (net) stations. This is achieved by the use of a single net address.  The  net  address  is  actually  an  additional  address  assigned  in  common  to  all  the  stations  that  are members of a specific net. Its address structure is identical to that used for individual station addresses (basic or extended, with or without stuffing, as necessary). When defining a net, each member station is automatically assigned a timeslot: by having each station answer a call request in a different timeslot, collisions are avoided.  A-6.2.3  Group Addresses  The  purpose  of  a  group  call  is  to  rapidly  and  efficiently  establish  contact  with  multiple non-prearranged (group) stations.  To make a group call, a calling ALE station uses a sequence of the actual individual station addresses of the called stations.  A-6.2.4  Special Addressing Modes – Use of Wildcards A “wildcard” is a special character,“?”, that a calling station can use to address multiple stations with a single call address. The following rules apply: • The total length of a calling address that includes wildcard(s) must be equal to that of the called station addresses.  • A  receiving  station  will  accept  a  wildcard  character  as  a  substitute  for  the  alphanumeric character  in  its  own  address  that  occupies  the  same  position.  This  means  that  the  wildcard character  is  a  substitute  for  any  of  36  characters  and  digits  (A  to  Z,  0  to  9)  in  the  Basic  38 character subset. • Multiple  wildcard  characters  can  be  used  in  different  positions  of  the  same  address  (basic  or extended). See Table  A-2 for examples of patterns using the “?” wildcard symbol.

Indicates that only the position occupied by an character (“A”, “B” or “C”) need be evaluated: the positions occupied by the “?” symbols can be ignored ? ? ?  “Standard” “wild-3” address word. Indicates that all of the three positions in this word can be ignored A B @  “Stuff-1” reduced address field, shown here for reference.

Use “global AnyCall” @ @ A  “Selective AnyCall”: see Table  A-1 @ @ ?  “Global AnyCall”: see Table  A-1 @ A ?  “Selective AllCall”: see Table  A-1 @ ? @  “Global AllCall”: see Table  A-1  ? @ ?  “Inlink address”: see page A-7  A-6.2.5  AllCall Addresses  An AllCall is a general broadcast that does not request responses and does not designate any specific addressee: a call with this address is accepted by any station, which then stops scanning and listens to the call. The most common use of AllCalls is in cases of distress: when in distress, it is more likely to want  to  make  any  available  connection  in  the  minimum  period  of  time  than  to  issue  a  call  to  an individual or to a select group. The global AllCall address is @?@. As a variation, the calling station can also use selective AllCall. Basically,  the  selective  AllCall  address  is  identical  in  function  to  the  global  AllCall,  except  that  it specifies the last single character of the addresses of the desired subgroup of receiving stations (that is, it replaces the ? with an alphanumeric – see  more details in Table  A-1). Any station whose address matches the pattern stops scanning and listens.
OM-E 2072-09689-00 A-7 The operator can always initiate an outgoing (transmit) AllCall, but the Micom-Z can be programmed to accept or ignore incoming (receive) AllCalls.  When a radio issues an AllCall, all the stations that are capable of receiving calls receive the AllCall.  In the scan mode, if the Micom-Z station is set to receive AllCalls, it stops scanning when an AllCall is  received.  If  an  AllCall  channel  has  been  defined,  then  outgoing  AllCalls  are  performed  on  that channel. If no AllCall channel has been defined, the call is performed on the first scanned channel of the net. In the Channel mode, outgoing AllCalls are performed on the currently active channel. NOTE You  can  transmit  an  AllCall  by  pressing  the  ESC  button  for  a  few seconds.  A-6.2.6  AnyCalls An  AnyCall  is  a  general  broadcast  similar  to  AllCall with  the  difference  that  it  requests  responses, without  designating  any  specific  addressee(s).  Therefore,  an  ALE  station  may  use  the  AnyCall  to generate  responses  from  essentially  unspecified  stations,  and  thus  it  can  identify  new  stations  and connectivities.  The global AnyCall address is @@?. As a variation, the calling station can also use selective AnyCall, which is identical in function to the global AnyCall, except that it specifies the last single character of the addresses of the desired subset of receiving stations (that is, it replaces the ? with an alphanumeric –  see  more  details  in  Table   A-1).  If  even  narrower  acceptance  and  response  criteria  are  required, double  selective AnyCall may  be  used:  this is identical to  selective  AnyCall, except  that its special address (@AB) specifies the last two characters that the desired subset of receiving stations. The operator can always initiate an outgoing (transmit) AnyCall, but the Micom-Z can be programmed to accept or ignore incoming (receive) AnyCalls. Any station accepting an AnyCall stops scanning, and then initiates a response in a randomly selected timeslot.  A-6.2.7  Self Addresses Stations can also use their own self addresses when making calls. This may be useful for self-test and maintenance purposes, etc.  The self address may be used only in specifically-addressed calls including a group call, but not in an AllCall or AnyCall. A-6.2.8  Null Address The null address is a special type of address that is not directed to, accepted by, or responded to by any station.  This address is intended for test and maintenance purposes, and to provide buffer time: for example, if a null address appears in a group call, no station will respond in the associated timeslot. A-6.2.9  Inlink Address  The inlink address, ?@?, is used to instruct all the stations participating in an already established link to accept and act upon the information sent with the inlink address. For example, any station can use the inlink address to send an AMD message that all the linked stations would present to their user.  The inlink address is recognized only after a link is established between two or more stations.
OM-E 2072-09689-00 A-8 A-7.  MESSAGES The  ALE  enables  you  to  create,  send  or  receive  alphanumeric  messages  (“paging”  messages)  in accordance with the AMD (Automatic Display Message) definition in Federal Standard FS-1045.  The messages are displayed on the receiving station LCD display, and can be up to 90 characters long. Messages  can  be  added  to  any  type  of  call,  whether  individual,  group,  net,  AllCall,  AnyCall, bidirectional  handshake,  etc.  You  can  create  up  to  12  messages,  and  can  edit  or  erase  any  of  the messages at any time. A-8.  USING THE CALLER STACK The caller stack is an internal memory that stores a list of unanswered calls. Each stack entry contains the self address of the calling station and a message (AMD) if any was  sent. You can view the list, return a call and view any message sent with any call. The stack can contain up to 10 calls. The radio records an address in the stack only once even if the same  caller  makes  repeated  unanswered  calls.  However,  if  the  same  caller  sent  calls  with  different messages, all such calls will be saved in the stack. Each stack entry is referred to as a Page. The appearance of the word STAK next to one of the function buttons of the LCD display indicates that  there is at least  one call in the stack. The STAK indicator is  automatically  turned  off when all pages in the stack have been erased.  The stack is arranged in FIFO order, that is, the first address that enters the stack is also the first that you see on the  display.  If the stack is  full  and a new  call  is received, the oldest call in  the stack is automatically erased. For convenience, addresses appearing in the stack can be easily added to the ALE address directory. A-9.  QUICK CALL During a call, the radio saves the latest destination information as the quick call information. When the user presses the PTT of the microphone or handset twice in rapid sequence, the radio automatically directs the call to that address.  In the ALE mode, channel information is also retained and used for quick calls.

OM-E 2072-09689-00 C-1 APPENDIX C  OVER-THE-AIR REMOTE DISABLE FUNCTION C-1.  SCOPE This  Appendix  covers  the  over-the-air  remote  disable  capability  of  Micom-Z  HF-SSB  transceivers operating in the ALE or CCIR modes. C-2.  OVERVIEW When a radio set is lost or stolen, it is necessary to prevent unauthorized use. Among other undesirable possibilities,  unauthorized  use  may  reveal  sensitive  information,  for  example,  frequencies  and  call signs.  Micom-Z is designed to prevent unauthorized use: an authorized operator can transmit a command to another radio set to effectively disable it, by erasing its operational parameters. This returns the radio set  to  the  unprogrammed  state  (after  receiving  the  command,  the  radio  continuously  displays  NOT PROG).  Therefore,  to  return  the  radio  to  a  usable  state,  it  must  be  programmed  by  means  of  the Micom Radio Control Application (MRC). The  over-the-air  remote  disable  command  is  transmitted  as  an  AMD  message directed to the target radio, using the paging function. Therefore, for this remote disable capability to be available, the target radio must operate in the ALE or CCIR mode. The command string can be individually programmed on each radio set. The factory-default string is KILL BILL, and it can be changed using the MRC (version 2.21 or higher). Make sure to change this default with a reasonably secure string (the maximum string length is 30 characters). C-3.  OPERATING INSTRUCTIONS  To send an over-the-air remote disable command: 1. Obtain the  parameters needed to establish ALE or CCIR communication with the target radio set (for example, address and ALE net parameters, or CCIR frequency table). 2. Prepare the AMD message with the prescribed command string (for example, KILL BILL), to be sent. 3. Call the target radio, attaching the AMD message using the PAGE function. NOTE When  the  target  radio  receives  the  call  request,  it  automatically restarts and starts displaying NOT PROG. Therefore, do not expect a confirmation for the disable command. C-4.  RESTORING THE RADIO TO NORMAL OPERATION  To return a radio set to normal operation, it is necessary to connect it to a PC running the MRC and program it with the appropriate parameters.  For  detailed  instructions,  refer  to  the  Micom  Radio  Control  Application  User’s  Guide,  Publication OM-E 2072-09602-10.
