24V Operation kit

The maximum output power of the transmitter is 125W PEP (Peak Envelope Power), with an average transmission duty cycle of 1 to 4, thus enabling even the CW (Continues Wave) signal to be transmitted at the maximum available power. Output power can be preprogrammed to one of four possible levels: 25W, 62W, 100W and 125W. Accurate sensors are used to keep the output power within the nominal value.

Reception

The radio includes mismatch protection. If the VSWR (Voltage Standing Wave Ratio) rises to more than 2:1, the transmitter is inhibited in order to avoid any damage and a relevant message is displayed.

The transmitter is thermally protected. If the transmitter internal temperature exceeds the maximum permitted temperature, the output power is automatically reduced to avoid any fault due to excessive heat.

The radio utilizes Digital Signal Processing (DSP) to implement reception functions such as demodulation, narrow filtering, automatic gain control, noise blanking and squelch.

The 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.

Overview

Frequency Sources

Power Sources

CW Keying Operation

Two types of frequency sources are available for the MICOM-H radio. The standard

0.6 PPM DTCXO frequency source which assures a frequency stability of better than ±18Hz. For frequencies lower than 10 MHz, it assures a frequency stability of better than ±6 Hz.

When higher frequency stability is required, the G478 0.1 PPM OCXO frequency source can be ordered. It will assure a frequency stability of better than ±3 Hz at 30 MHz.

The radio is designed for 13.8 V±20% negative-ground operation and may be connected to a standard 12 V battery, or with the optional kit to a power supply of 24V±25%.

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 the Morse key between CW (pin #10) and ground (pin #18) at the accessory connector. If you wish to operate CW keying with external headphones, use the CW cable supplied with the radio. This will enable a standard PL55 headphone and standard PL99 Morse key to be connected to the accessories connector.

Radio Programming

The following radio features can be programmed:

■

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

■

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

■

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

Most radio functions can be programmed directly from the front panel of the radio as described in the

Radio Programming

chapter.

Maintenance

Preventative Maintenance

This section provides maintenance information for the MICOM-H. Correct installation and maintenance will ensure on-going operation of your radio set.

If an internal problem is suspected, the BITE (Built In Test Equipment) will assist you in locating the source of the problem and in informing your service representative.

System Integrity

Periodic Calibration

Using BITE

Periodically check the integrity of your system, by examining the power source, cables, coaxes, connectors, antenna tuner (if used) and antenna. Carefully check that no damage has been caused to your cables, pay extra attention to runway through holes and bent cables.

To maintain the frequency accuracy of your radio, the internal frequency source must be calibrated after 3, 6 and 12 months of operation in the first year, and once a year thereafter. Please ensure that your radio is calibrated on time.

Every time the radio is turned on, a self-test procedure is activated. If an internal malfunction is found, an error message will be displayed. Please contact your service representative and report the indicated malfunction or error. A list of possible error

messages is given on page 48.

Troubleshooting

If the radio is malfunctioning, try to solve the problem as follows:

Problem Troubleshooting

Blank Display

Display present but weak or no receive signal or noise

Engine noise picked up by the antenna

Check whether:

• DC power cable is connected properly to the radio and battery.

• A 7.5A fuse is installed in the fuse holder located on the green wire of the DC power cable.

Check whether:

• Connection of antenna to antenna tuner and antenna tuner to radio cables (loose or broken connections).

• Correct programming of operating channel (frequency, mode of operation, etc.).

Determine by observing difference in the reception by turning the Engine ON/OFF.

Ve ri fy th at :

• The ground leads are properly connected, all power wires and ground leads are as short as possible

• The Noise Blanker (if installed) is enabled.

Poor or no transmission

If the problem persists:

• Install noise reduction Kit TLN8845.

Check whether:

• A 30A fuse is installed in the fuse holder located on the red wire of the power cable.

• Proper grounding cables are connected from the radio and from the antenna tuner to the vehicle chassis.

• While speaking, check RF power bars for activity. The resulting RF power output is displayed in approximately 15 W increments (bars) being added from the bottom of the display upwards.

• Three or more bars disappear from the RF power bar display. There may be a problem in the antenna system. If the antenna cabling or the antenna mast rigging position has changed since the antenna was last tuned, the antenna tuner will not be adjusted automatically. To retune the antenna tuner, press the ENTER key. If transmission is still poor, inspect the tuner, antenna and ground plane for loose connections or misplaced parts. If no loose connections are found, call your service representative for assistance.

• There are no bars at the RF power bar graph. Indicates low transmitter power, which can be caused by a faulty microphone, faulty transmitter, overheating, or defective antenna system.

The vehicle frame makes the best ground, but body structural reinforcement members are also suitable for grounding purposes. The ground lead should be as short as possible.

DC Connector J4

Reduction of Vehicular Noise

DC connector J4 is mounted on the rear panel of the radio. It is used to feed the radio with the required power from an AC to 13.8V power supply or from the battery. The following table lists the function of the DC connector lines.

Table 3. Connector J4, Pin Connections

No. Pin Name Description

TX Power Used to deliver high currents (up to 28 Amp) to the

radio, mainly for the transmitter circuitry

Ground Used as return line for receive and transmit lines

RX Power Used to deliver relatively low currents (up to 3 Amp)

to the radio, mainly for the receiver circuitry

Most vehicles are subject to several noise sources which greatly disturb a received signal. The most noisy sources are the high voltage ignition sparks that are produced at the vehicle's plugs. Alternator activity also generates significant noise.

By following these insulation guidelines, and if necessary by adding certain damping components, it is usually possible to reduce vehicular noise:

Keep your antenna tuner and antenna as far as possible from the engine compartment.

Connect the primary power lead of the radio directly to the battery instead of the starter relay. The battery acts as a large capacitor (about one farad for 50 A-H capacity batteries) by passing the noise to ground.

If necessary, connect 0.01 - 0.1 mF capacitors across the primary leads of the coil and across the alternator output.

Keep your DC and RF cables as short as possible.

If your vehicle does not have a resistive ignition wire, it is recommended to replace it with such a wire.

The MOTOROLA RF noise reduction kit for alternator equipped vehicles (TLN8845) includes some useful accessories for noise reduction, including a resistive ignition coil suppressor cable. In severe noise conditions, you may find this kit helpful.
