NOTE
• Only rotate SQUELCH until the
hissing stops. If you continue to
rotate it clockwise, you will be
unable to receive any signals.
• You may want to purchase an
SWR (Standard Wave Ratio)
meter to measure your range
and signal strength. This will
enable you to adjust your
antenna for maximum range,
and determine the best position
for RF GAIN. See your SWR
meter owner's manual for
instruction on how to use it.
