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.)

SQUELCH CONTROL: This switch is used to eliminate background noise being heard
through the receiver, which can be disturbing when no transmission is 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.
