If you’re having difficulties in adjusting your antenna, check the following:
a.
All doors must be closed when adjusting the antenna
b. Make sure the antenna base is grounded.
c. Check your coaxial cable routing (it may be pinched when routed into the car)
d. Try a different location in 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 polls or light post, fences, etc.)
NOTE
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 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 4 watts. When the external speaker is plugged in, the internal speaker is
disconnected.
FRONT PANEL
1. ON/OFF VOLUME CONTROL :
This knob controls the volume and power to
the radio. To turn radio on, rotate the knob clockwise. Turning the knob further will
increase the volume of the receiver.
2. SQUELCH CONTROL :
This switch is used to eliminate background noise being
heard through the receiver which can be disturbing when no transmission are being
heard through the received. To use this feature, turn the switch fully
counterclockwise and then turn clockwise slowly until the background noise is just
eliminated. Further clockwise rotation will increase the threshold level which a
signal must overcome in order to be heard. Only strong signal will be heard at a
maximum clockwise setting.
3. MIC GAIN CONTROL :
Adjust the microphone gain in the transmit modes. This
controls the gain to the extent that full talk power is available several inches away
from the microphone.
4. RF GAIN CONTROL :
This control is used to reduce the gain of the RF amplifier
under strong signal conditions.
