Frequency Sources
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.
Power Sources
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%.
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 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.
