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 standard antenna connectors of type SO-239

both located on rear panel; for easy connection to standard PL-

259 coax plugs. 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

fixed operation. Some of these noise sources are; fluorescent buzz,

nearby commercial broadcast, electrical appliance, 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 to 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

Public address

An external 8 ohms, 3-Watt speaker must be connected to the PA

jack located on the rear panel when the transceiver is used as a public

address system. The speaker should be directed away from the

microphone to prevent acoustic feedback. Physical separation or

isolation of the microphone and speaker is important when operating

the PA at high output levels.

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.
