Introduction

Welcome to the MICOM-3 HF-SSB radio family! Your choice of a MICOM-3 radio means you have selected the highest of standards in design, quality, and performance. This manual is designed to acquaint you with the features, care, and installation of the following MICOM-3 radios to better serve all your communication needs:

MICOM-3F

Transceiver for long range wireless voice, fax, data and email communication, with built-in front panel, for fixed and mobile use.

MICOM-3T

Transceiver for trunk mounting with separate control box, saves valuable cabin space in mobile use.

MICOM-3R

Ruggedized transceiver with military handset and connectors, for fixed and mobile use in applications requiring the utmost dependability and reliability.

In Appendix A, you will also find information on the micomTrooper 3, the 5-to-50W backpack transceiver version of MICOM-3 transceiver, and its Battery Charger, FLN9541.

For convenience, the manual is divided into two Parts:

• Part I – Operation and Installation (this Part) presents the information you need to familiarize

with MICOM-3 radios and operate them efficiently. It also explains how to install your radio set and correct most of the problems that may occur during its operation.

• Part II – Manual Programming explains in detail how to program manually any radio parameter

from the MICOM-3 front panel, instead of using the dedicated MICOM-3 Radio Control Application (MRC) or Radio Service Software (RSS). For this purpose, you will find in this Part explanations and step-by-step instructions that expand the general radio programming of Part I.

Note

In both Parts of this manual, the generic term MICOM-3 is used for information applicable to all the transceiver versions. The complete transceiver designation is used only for information applicable to a specific equipment version.

MICOM-3F/3T/3R HF-SSB Owner’s Guide

MICOM-3 HF-SSB Radio Features

• Digital Signal Processing (DSP)

• Built-in Test Equipment (BITE)

• RF power indications

• 200 channel capacity, simplex or half-duplex

• Channel scan or Automatic Link Establishment (ALE) per MIL-STD-188-141B/FED-STD-1045

• MultiNet function for seamless integration of different HF radio networks in one network

Transmitter Features

The maximum output power of the transmitter is 125 W PEP (Peak Envelope Power). The average transmission duty cycle is up to 1:4, thus enabling even CW (Continuous Wave) signals to be transmitted at the maximum available power. Output power can be preprogrammed to one of four levels: 25W, 62.5W, 100W and 125W. Accurate sensors are used to keep the output power at the selected value.

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 VSWR (Voltage Standing Wave Ratio) rises to more than 2:1, the transmission will be inhibited to avoid damage and a message will be displayed.

Receiver Features

The radio utilizes digital signal processing for implementing most of the receiver functions, e.g., demodulation, narrow band filtering, automatic gain control, noise blanking, tunable notch filter, squelch, etc. An automatic digital noise blanker is activated whenever repetitive noise (e.g., ignition spikes) is encountered in the received signal. 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.

Frequency Sources

Two types of frequency sources are available for the MICOM-3 radio. The standard 0.6 ppm DTCXO frequency source which assures a frequency accuracy of better than ±18 Hz. For frequencies lower than 10 MHz, it assures a frequency accuracy of better than ±6 Hz. When higher frequency accuracy is required, the G112 0.1 ppm OCXO frequency source can be ordered. It will assure a frequency accuracy of better than ±3 Hz at 30 MHz.

Page 21

Introduction

Power Source

The radio is designed for 13.8 V ±20% negative-ground operation and may be connected to a standard 12 V battery.

CW Keying Operation

When the CW key is pressed, the radio transmits a continuous wave (at the full programmed power) and stops transmission when the key is released. CW keying operation is enabled by connecting a Morse key to the accessories connector. If you wish to operate CW keying with external headphones, the S809 Interface cable can be used, thus enabling a standard PL55 headphone and standard PL99 Morse key to be connected to the accessories connector.

Programmable Features

The radio can be programmed using a PC running the MICOM Radio Control Application (MRC) or the Radio Service Software (RSS). The following radio features can be programmed:

• Up to 200 simplex/half duplex channels supporting SSB (J3E), AME (H3E), or Pilot (R3E) modes.

• Up to four levels of output power (up to 125W PEP and average).

• Five scanning groups of up to 200 channels, each with guard channel.

General Procedures

This section provides general procedures that will help you start using your MICOM-3 radio and get the most of its advanced features.

Most of the activities that can be performed by you (selection of operating mode, status display, programming, testing, etc.) are done using the keypad together with the four navigation keys (up, down, left and right) and the front panel display.

To simplify operation, MICOM-3 uses soft keys that let 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 the selection, you use navigation keys to reach the desired parameter value or

operation, and then confirm the selection by pressing the ENTER key.

• To let you go back to previous options, there is an ESC key.

Using the Keypad

Each key is imprinted with a numeral and several letters. These characters are accessed in clockwise order, as follows:

• A single key press enters the numeral

• Two consecutive key presses enter the first letter

Esc

• Three consecutive key presses enter the second letter

• Four consecutive key presses enter the third letter.

• Five consecutive key presses enter the fourth letter.

• To enter a blank space, press

When entering frequencies, use the

twice.

key as a decimal point, if needed. In the ALE mode, the *

key is also used to enter the wild-card character (? or @).

Note

To enter the ampersand @ symbol, press the key.

Example: to enter “MIKE 01”:

Press

twice (for the letter M).

four times (for the letter I).

three times (for the letter K).

three times (for the letter E).

twice (for the blank space).

once (for the numeral 0).

Function Keys

The function keys F1, F2, F3 and F4 appearing next to the display are soft keys used to select options which depend on the current radio mode. The current function of each key is shown in the options area of the display, next to the key. For example, on the

MICOM-3

PROG

PROG screen you can press F2 to start programming the ALE parameters.

If a certain function key is not used, no label appears next to the key (see for example F4), and pressing that key has no effect.

Scroll (MORE) Key

The MORE key is used to scroll the options appearing in the options area of the display.

Up/Down Scroll Keys

The up and down scroll keys are used to scroll between values that are already programmed into the radio. For example:

• In the Channel mode, pressing the up or down scroll key once lets

you view the previous, respectively next, programmed channel. Pressing either key continuously scrolls the channels in the selected direction.

RAD ALE LANG

• In the Frequency mode, you can change the frequency in the

corresponding direction.

• In the radio Programming mode, you can use these keys to scroll

among the programmable parameters.

Selection from List of Predetermined Values

When the parameter you want to select can assume only one of several predetermined values, you select the desired value by pressing the function keys:

• F1 enters the lowest possible value (or OFF)

• F4 enters the highest possible value

• F2 and F3 increment or decrement the value. When you reach either

end, the corresponding key disappears

You cannot use the keypad to enter a value for such parameters.

Toggle Mode

When the function being set can only be toggled on or off, one function key will be marked YES and another NO.

To expedite turning on and off often-used functions (for example, turn the squelch on or off) only one key is used. In this case, just press the key assigned to the function to be toggled: the new state is shown for a few seconds, and then disappears as it takes effect immediately.

Numeric Edit Mode

When you need to enter a number in a field, or edit the number, you type the desired digits on the keypad. A blinking cursor _ indicates the location being edited.

In addition, the following function keys are available:

BACK (F3) Erases the last digit.

CLR (F4) Erases all newly entered digits and restores the original value.

View Mode

When the string to be displayed is longer than the number of characters that fit in one line (for instance, with long addresses or messages), the view mode enables scrolling to the rest of the string.

The view mode is indicated by the symbol <-> next to one of the function keys.

When you press <->, the key functions change:

HOME (F1) Scrolls to display the first character of the string. <−− (F2)

−−> (F3)

Scroll one character to the left or right, respectively. If you press either key continuously, the scrolling continues at a rate of four characters per second.

Transmitting and Receiving

Basic Operating Instructions

Notes

• When transmitting, the RF output of the radio must be connected to an

antenna installed as explained in the Installation section – page 104 (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 on the side of the microphone or handset, and speak slowly and clearly after the channel is clear. The TX LED turns on and remains lit until the PTT button is released to indicate that you are “on-the-air”. 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.

➤ 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 speaker, or in the handset or headset connected to the radio. 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

Strong received signal

received signal strength.

Tx Bar

PTT Types

The radio can receive and transmit in response to four different types of PTT signals:

• MIC PTT – PTT from the microphone or handset connected to the front panel connector;

transmits your voice.

• Voice PTT – PTT from an accessory connected to the radio set through its rear panel accessories

connector; it causes the radio to transmit the voice signal provided by the accessory device.

• Data PTT – PTT from an accessory connected to the radio set through its rear panel accessories

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 accessories

connector; it causes the radio to switch to the CW (Morse) transmission mode.

Note

The PTT type is automatically identified according to the type of device that generated it, and the radio operating mode is automatically adapted for best performance with the signal expected for the detected PTT type.

For CW communication, the squelch should be set to OFF.

Page 36

MICOM-3F/3T/3R HF-SSB Owner’s Guide

Filter Bandwidth

The filter bandwidth depends on the type of signal to be transmitted and received. A default filter bandwidth can be configured for each channel (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.

Bandwidth set to: Service type: Filter changes after:

2.1 K Data First data PTT

2.7 K Voice First microphone or voice PTT

3.0 K Data First data PTT

3.3 K High speed data, vocoder,

First data PTT

or voice privacy device

CW Morse First CW PTT

LSM Low speed data First data PTT

Note

When the filter bandwidth is set to CW, the following CW bandwidths can be configured in the Programming mode: 0.25 K, 0.5 K or 0.8 K.

Using the Channel Mode

The Channel mode is used for choosing channels already programmed in the MICOM-3.

The following sections describe how to use the Channel mode.

Selecting the Channel Mode

In general, the MICOM-3 automatically enters the Channel mode when turned on, and starts using the last used channel.

If not, use the Menu screen to select the Channel mode: this is the first item on the menu you see when you press MENU.

Using Automatic Link Establishment (ALE)

The MICOM-3 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 incorporates all the advanced data transmission techniques required by MIL-STD-188-141B and FED-STD-1045.

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.

The following sections present an overview of MICOM-3 ALE capabilities and services, and then provide instructions on using ALE.

ALE Capabilities and Features

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).

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.

Page 53

Using Automatic Link Establishment (ALE)

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%.

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 4 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 4. 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.

Page 54

MICOM-3F/3T/3R HF-SSB Owner’s Guide

• 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.

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.

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.

Bidirectional Handshake

The bidirectional handshake is an operator-initiated procedure used to exchange LQA scores with other stations without establishing a link.

Note

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.

The MICOM-3 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).

Page 55

Using Automatic Link Establishment (ALE)

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.

Selective Calling

MICOM-3 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.

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 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 2 for utilization guidelines in the special addressing modes.

Note

MICOM-3 has the capacity to store and use 100 addresses of up to 15 characters each. MICOM-3 will reject addresses longer than 15 characters, and will notify you with an UFA WRONG message.

In the following sections, “A,” “B,” “C” or “D” indicates any alphanumeric character other than “@” or “?”.

Address and Call Types

ALE stations, including the MICOM-3, 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.

Page 56

MICOM-3F/3T/3R HF-SSB Owner’s Guide

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 1).

The wildcard symbol cannot be included in an individual station address, nor in a call request to an individual station.

“AllCall” global address (see also Table 2): all the stations stop and listen (unless this function is inhibited)

“Selective AllCall” global address: each station with the same last character “A” stop scanning and listen (unless this function is inhibited

“AnyCall” global address (see also Table 2): all the stations stop scanning and respond in randomly selected timeslots (unless this function is inhibited)

“Selective AnyCall” address: each station with same last character(s) “A” (or “B”) stops scanning and responds in a randomly selected timeslot (unless this function is inhibited), using its own address

“Double selective AnyCall” address: each station with same last characters “AB” (or “CD”) stops scanning and responds in a randomly selected timeslot (unless this function is inhibited), using its own address

“Null” address; all the stations ignore this address. The null address intended for use in test and maintenance, or to create an extra “buffer” timeslot

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.

Page 57

Using Automatic Link Establishment (ALE)

Group Addresses

The purpose of a group call is to rapidly and efficiently establish contact with multiple nonprearranged (group) stations.

To make a group call, a calling ALE station uses a sequence of the actual individual station addresses of the called stations.

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 2 for examples of patterns using the “?” wildcard symbol.

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 1). Any station whose address matches the pattern stops scanning and listens.

The operator can always initiate an outgoing (transmit) AllCall, but the MICOM-3 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-3 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.

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

Page 59

Using Automatic Link Establishment (ALE)

the addresses of the desired subset of receiving stations (that is, it replaces the ? with an alphanumeric – see more details in Table 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-3 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.

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.

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.

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.

Using the MultiNet Feature

Normally, a radio operating in the ALE mode receives and transmits only in its currently selected net. However, there are operational scenarios in which it is beneficial to enable radios to use the ALE functions while still being aware of what is going on in additional nets (for example, firefighters and paramedics must often respond to the same emergency), and be able of answering a call in another net. For this purpose, MICOM-3 radios offer the MultiNet feature.

When the MultiNet feature is enabled, a MICOM-3 radio can operate on multiple nets (up to 20). The operating characteristics then change as follows:

• Channels: each net has a group of assigned (receiving and associated transmitting) frequencies.

The radio scans the channels in one net after the other, until all the nets have been scanned.

• Station addresses (the self-address and the net address used when responding to calls): the radio

responds according to the self-address assigned to the station in its currently selected net (for a total of up to 20 self-addresses).

• Sounding: each radio sends soundings only within the currently selected net. Each radio scans all

the channels in the currently selected net, one by one. Sounding is started 10 minutes after the unit is switched on. The sounding group interval is determined according to the programmed Sounding Auto Time.

Page 60

MICOM-3F/3T/3R HF-SSB Owner’s Guide

During operation, the MICOM radio scans all the frequencies included in the defined nets:

• When the radio receives a call, it responds with the self-address that is programmed in the radio

for that net.

• When initiating a call, you select the net you want to transmit to, and then select an address (a

specific station, or any other type of address you wish to use). The radio then looks up the frequencies that are associated with the station you call and uses only those frequencies to call that station.

• LQA exchanges and sounding use only frequencies associated with the currently selected net.

Note that the time needed to scan multiple nets may be rather long, even when using the rather fast 5 channels/second scan rate. Moreover, the duration of a call set up request must also be long enough to ensure that your call reaches all the relevant nets. You can use the MaxScanCh parameter (an ALE programming option) to change the duration: the default, when AUTO is selected, is about 7 seconds; however you can select a different value, in the range of 1 to 59 seconds. Make sure to use the minimum value that ensures all the nets will hear your call set up request, because long durations are very disruptive.

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.

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.

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.

Page 61

Using Automatic Link Establishment (ALE)

Using ALE Functions in the Channel Mode

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 (F1) key is displayed even in the Channel mode.

The only restriction is that in the Channel mode, MICOM-3 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.

Entering the ALE Mode

To use the ALE mode, first it must be enabled as explained below.

Enabling the ALE Mode

Receiving and Transmitting Calls in ALE Mode

The MICOM-3 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.

Note

MICOM-3 also supports the MultiNet feature. When this feature is enabled, it can receive and transmit ALE calls in several different nets (up to 20). See details on page 41.

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 48 to 52.

Receiving Calls in ALE Mode

When your MICOM-3 receives a call, it displays its type and the source address.

MICOM-3

You are also notified when a message is attached: if a message is received, the name of the calling station is preceded by an exclamation mark.

For any type of call, if the ALERT attribute is programmed to YES, you will hear the alert tone when a message is received.

➤ 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.

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.

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 the word STAK next to the F3 key, 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 (F3).

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 <-> (F4) to activate the view mode.

2. Use the UP/DOWN keys to view any additional calls in the stack.

Page 70

MICOM-3F/3T/3R HF-SSB Owner’s Guide

➤ To return a call to a station registered in the stack:

1. Press STAK (F3).

2. Use the UP/DOWN keys to scroll to the required call.

3. Press CALL (F1).

4. Press PAGE (F2) if you want to attach a message when you reply to the call.

5. Press CHAN (F3) if you want the call to be initiated on a specific channel in the currently used net.

Note

The CHAN (F3) key is displayed only if the radio is in the ALE mode.

6. Press SEND (F1) 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 (F3).

2. Use the UP/DOWN keys to scroll to the required call.

3. Press ERAS (F2).

4. Press YES (F1) to confirm or, NO (F2) to cancel the deletion.

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:

MICOM-3

Press the ESC key. This disconnects the link and returns the radio

END CALLING

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.

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):

• When the MultiNet function (page 41) is disabled, the destination net

is always the currently selected net (its number is displayed on the LCD while the radio is scanning). Therefore, if you do not want to select a different net, you can skip directly to the selection of the destination station(s).

• When the MultiNet function is enabled, first you must always select a net and then the

destination station(s).

To expedite the transmission of an AllCall, you can send a global AllCall by pressing the P/ESC key for a few seconds.

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

You cannot select the channel on which an outgoing AllCall will be sent: outgoing AIICalls are sent on the AllCall channel defined for the currently selected net, or on the best scanned channel of the net.

Note

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.

If so required, you can set your radio so that it cannot send AIICalls.

When radios in other nets have their MultiNet feature enabled, AIICalls may also reach these radios. See details on page 41.

➤ To send global AllCall using the ESC key:

1. Press ESC continuously for a few seconds. The radio starts sending the GL AllCall.

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 as explained on page

37, 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.

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

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).

If so required, you can set your radio so that it cannot send AnyCalls.

Note

When radios in other nets have their MultiNet feature enabled, AnyCalls may also reach these radios. See details on page 41.

You can send three types of AnyCalls (see also description of addressing modes on pages 37 to 41):

• 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.

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-3 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 pages 37 to 41, which present 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 53.

You can press STOP (F1) at any time to end the call sooner.

Bidirectional Handshake

The bidirectional handshake is used to exchange LQA scores with other stations without establishing a link.

Note

The MICOM-3 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).

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.

Note

Before starting, you may want to select a different net to use: see instructions on page 53.

When MultiNet is enabled, you will be prompted for a net number as soon as you press CALL (F1) to start a call.

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 (F2) to enter the LQA menu.

2. Press SOND (F2).

3. Press ON (F1) to start manual sounding, or OFF (F2) to stop an ongoing sounding process.

Notes

• The radio automatically returns to ALE mode when sounding is stopped.

• When the radio transmits a sounding signal, the Tx bar is visible.

Using Automatic Link Establishment (ALE)

Using the Inlink Function

When the inlink function is enabled (see instructions in the ALE Options Configuration section starting on page 91), the stations participating in a

call are automatically notified by a DISC message whenever another participant leaves (disconnects from) the call.

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.

Notes

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 PTT time-out interval (PTOT) programmed under the ALE Options Configuration section), 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 (F4) key.

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.

If net 1 is not programmed, there is no ALE functionality in the Channel mode, even if the ALE option is turned on.

Using the Programming Mode

Note

This section provides concise instructions for using the PROG mode. If you need detailed instructions, refer to Part II of this manual – Manual Programming.

The Programming (PROG) mode is used to program the parameters needed by your radio set:

• Language – the language used on the MICOM-3 display. The default language is English,

however you also select French or Spanish.

• Radio parameters – the parameters for communication in your environment and in the radio nets

you use most of the time. Some of these parameters are stored as channels.

• ALE parameters – the parameters needed to use the ALE function. Some of these parameters are

stored as nets.

You can also use the PROG mode to program the parameters needed by the optional vocoder or by VP-116 voice privacy unit, when used by your radio set. To find details on the selections available to you on the PROG menu, use Figure 6 (page 79) and Figure 7 (page 80).

Note that MICOM-3 lets you change the currently-used parameters on-line, as required in any particular situation. When you select another channel or net, the changes are discarded and the programmed values are used again.

Note

The Programming mode is accessible only if the radio is not locked. See the Locking the Radio section on page 32.

GET retrieves a channel already programmed in MICOM-3. Retrieving a channel retrieves all the parameters defined for that channel. You can store these parameters as a new channel using the STOR function, and then edit the parameters as required.

Store the current set of parameters in a selected channel.

GET and STOR are used to copy the channel parameters from one channel to another.

ERAS is used to delete (erase) a channel. Actually, this action only replaces the user-modified parameters of the channel with the factory-default parameters, but marks the channel as not programmed.

Select the channel transmit power level. Four transmit power levels can be selected:

• LOW – 25 W nominal

• MED – 62.5 W nominal

• HIGH – 100 W nominal

• MAX – 125 W nominal.

Select the channel frequency. MICOM-3 offers four frequency options:

• SMPX (Simplex Frequency): the same frequency is used for both transmission

and reception.

• DPLX (Duplex Frequency): transmits on one frequency and receives on a

different frequency.

• RXO (Receiving Only Frequency): defines a frequency for reception only.

Transmission on that frequency is disabled.

• TXO (Transmitting Only Frequency): defines a frequency for transmission

only. You cannot receive on that frequency.
