Setting the squelch threshold
The job of a s squelch circuit is to reduce audible noise. It
eliminates noise during pauses in the audio signal by
muting the receiver every time the audio level drops below a
defined threshold. The SQUELCH control on the receiver sets
this threshold. Use the SQUELCH control with care! If the
squelch threshold is too high, the squelch will not only cut
out noise but mute quiet audio signals as well because the
squelch responds to the detected voltage and cannot distin-
guish between wanted signal and noise. Besides that, a too
high squelch treshold also decreases the usable range.
