Think of your Squelch Control as a gate for incoming
signals. If you turn the Squelch Control fully clockwise, it
raises the "squelch gate" so high that no signals get
through.
If you turn the squelch control fully counter-clockwise, it
lowers the "squelch gate" so low that everything gets
through - noise, weak signals and strong signals.
The Desired Squelch Setting, (DSS) only allows actual
transmissions to come through. This effectively blocks out
unwanted noise.
