Squelch
The SQUELCH (SQ) control allows you to set the “threshold” at which
signals can be heard. This allows you to determine how strong a signal
must be before it “breaks squelch”. That is, how strong it must be before
you can hear it. This keeps static and unwanted weak or distant signals
from breaking into your desired conversations.
