INSTALLATION:
Location/Connection
The transceiver should be placed in a convenient operating location
close to an AC power outlet and the antenna lead in cable(s).
The transceiver is powered with the AC power cord set. Proceed as
follows to complete all necessary connections to the transceiver.
1. Your transceiver has a standard SO-239 connector on the rear
panel for easy connection to standard PL-259 coax plug. If the
coax antenna cable must be made longer, use coax cable with
impedance of 50 ohms and use only enough cable to suit your
needs. This will insure a proper impedance match and maximum
power transfer from the transmitter to the antenna.
2. AC Power Operation: Use 120 volts AC.
Noise Interference
There are several kinds of noise interference you may encounter in
base station operation. Some of these noise sources are; fluorescent
buzz,
nearby
commercial
lawnmower, and electrical storms, etc. Commercial products are
available to reduce interference from these sources. Consult your
dealer or professional amateur radio supply shops.

Antennas
Antennas are purchased separately and include installation
instructions. Numerous type of antennas are available that range from
emphasis on easy of installation to emphasis on performance. Often
the difference in performance between many of the antenna is
modest.
1. Vertical Ground Plane Antennas:
These are omni-directional antennas that provide optimum
performance for contacting other fixed stations using vertical type
antenna in addition to all mobile stations. For medium long range
communications work.
2. Directional Beam Antennas:
Highly efficient and directional antennas generally intended for
fixed-to-fixed very long range communications.
Remote Speaker
The external speaker jack (EXT. SP.) on the rear panel is used for
remote receiver monitoring. The external speaker should have 8
ohms impedance and be able to handle at least 3 watts. When the
external speaker is plugged in, the internal speaker is disconnected.
Note: The PHONE jack on the front panel overrides both external
and internal speakers. When the plug from a headphone is plugged
to the PHONE jack, both internal and external speakers are silenced
simultaneously.
