Adjusting the squelch level
Squelch is a function that allows the audio to be heard only
while receiving a signal that is stronger than a set level. You
can adjust the squelch threshold level.
A higher level blocks weak signals, so you receive only
stronger signals. A lower level allows you to hear weak
signals including noise.
Adjust the squelch level when you want to:
