WARNINGS, CAUTIONS AND NOTES
The following notations are used to place special emphasis on procedures, or to call attention to
precautionary measures.
WARNING
An operating procedure, practice and so forth, which if not followed
correctly, could result in personal injury, or loss of life.
CAUTION
An operating procedure, practice and so forth, which if not followed
correctly, could result in damage to, or destruction of equipment.
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
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.
1-1
OM-E 2072-09689-00
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.

The audio accessories are for
illustration purposes only, and may
vary in accordance with preferences.

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.

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 P key.

Meaning
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.
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
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.

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.
2-5.3
Strong received signal
Weak received signal
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.

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.

OM-E 2072-09689-00
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.

2-12. 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.

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.
FROM
!1002
For any type of call, if the ALERT attribute is programmed to YES, you
will hear the alert tone when a message is received.
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.
FROM
1002
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.
2-30
OM-E 2072-09689-00
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.

2-12.3.2.1
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.
2-33
OM-E 2072-09689-00
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).

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:

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.

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.
2-43
OM-E 2072-09689-00
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.
2-44
OM-E 2072-09689-00
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.

•
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.
2-46
OM-E 2072-09689-00
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.
2-47
OM-E 2072-09689-00

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
2-12.3.5
•
The radio automatically returns to ALE mode when sounding is
stopped.
•
When the radio transmits a sounding signal, the Tx bar is visible.
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.
2-48
OM-E 2072-09689-00
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.
2-49
OM-E 2072-09689-00
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.

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. Press MENU to display the Menu screen.

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

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.

OM-E 2072-09689-00
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!

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.

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.
3-4
OM-E 2072-09689-00
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.

If the battery is located in the rear section of the vehicle, the power cable extends to the battery
location.
• The upper installation (location 1 in Figure 3-12), is recommended over the front installation
(location 2 in Figure 3-12) because of the covering that protects the control head from direct
sunlight.
• 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 high voltage lead-in cable length.

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.
3-13
OM-E 2072-09689-00
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
3-7.2.1
What to Do If ...
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.

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.

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:
3-16
•
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
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.

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.

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
GET
Description
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 usermodified parameters of the channel with the factory-default parameters, but marks the

Programming Nets
When programming a net, you can set the net names, define the net members, add channels, configure
various options, copy parameters from a defined net or erase an entire net.
4-4.1.1
Overview of Net Programming
The net programming mode enables you to view and edit the configuration of each net. 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).
4-10
OM-E 2072-09689-00
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)).
• CHAN
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

OM-E 2072-09689-00
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
4-4.3
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).
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).
4-12
OM-E 2072-09689-00
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.

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.
4-17
OM-E 2072-09689-00
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.

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.

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).

Figure A-1. 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.
A-2
OM-E 2072-09689-00
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-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.

“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
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.

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.
A-6
OM-E 2072-09689-00
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.

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.

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.
