D. Try a different location on your car (keeping in mind the radiation pattern

you wish)

E. Is the antenna perfectly vertical?

F. Try a different location in your neighborhood. Stay away from large

metal objects when adjusting (metal telephone or light posts, fences, etc.).

The transceiver will operate into an SWR of 2 to 1 indefinitely

and sustain an SWR of 20:1 for a maximum of 5 minutes at rated

operating conditions.

EXTERNAL SPEAKER

The external speaker jack (EXT.SPK) 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 4 watts. When the external speaker is plugged in, the internal

speaker is disconnected.

Operation

CONTROL FUNCTIONS

There are thirteen controls and three indicators on the front panel of your

transceiver.

FRONT PANEL

1. OFF/ON/VOLUME (inner dual concentric). Turn clockwise to apply power

to the unit and to set the desired listening level. During normal operation, the

VOLUME control is used to adjust the output level obtained either at the

transceiver speaker or the external speaker, if used.

2. SQUELCH (outer dual concentric). This control is used to cut off or

eliminate receiver background noise in the absence of an incoming signal. For

maximum receiver sensitivity it is desired that the control be adjusted only to

the point where the receiver background noise or ambient backgrounds noise is

eliminated. Turn fully counterclockwise then slowly clockwise until the

receiver noise disappears. Any signal to be received must now be slightly

stronger than the average received noise. Further clockwise rotation will

increase the threshold level, which a signal must overcome in order to be

heard. Only strong signals will be heard at a maximum clockwise setting.

3. MIC GAIN (inner dual concentric). Adjust the microphone gain in the

transmit and PA modes. This controls the gain to the extent that full talk power

is available several inches away from the microphone.

4. RF GAIN CONTROL (outer dual concentric). Use to reduce the gain of the

RF amplifier under strong signal conditions.
