Information for Safe, Efficient Operation
Exposure to
Radio Frequency
Energy
In August 1996, the Federal Communications Commission (FCC) adopted updated
RF energy exposure guidelines for wireless products regulated by the FCC. These
guidelines are consistent with the safety standards previously set by both U.S. and
international standards bodies. The design of your Motorola radio complies with the
FCC guidelines and these standards:
■
American National Standards Institute (C95.1-1992)
■
National Council on Radiation Protection and Measurements
NCRP-1986)
■
International Commission on Non-Ionizing Radiation Protection
(ICNRP-1986).
To assure optimal radio performance and to ensure that exposure to RF energy is
within the guidelines in the above standards, install antennas correctly, following
recommended installation procedures.

Overview
Welcome to the Motorola HF-SSB radio family! Your choice of a MICOM-H radio
means that you have selected the highest of standards in design, quality, and
performance.
The compact sized MICOM-H is an advanced ruggedized Digital Signal Processing
(DSP) HF all-band transceiver intended for very wide area radio communications. It
combines sophisticated voice, data, fax and e-mail solutions with a high signal
quality and reliability, while remaining very simple to operate.

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.
