C. Check your coaxial cable routing (it may be pinched when routed

into the car).

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 eighteen controls and three indicators on the front panel of your

transceiver.

FRONT PANEL

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.

SQUELCH CONTROL (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.

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.
