(c) SQ: Indicates or selects the SQUELCH level: Squelch is a control that will not
allow the audio signal to turn on before the RF signal reaches a certain
strength. Too low of a squelch level will allow a noisy audio signal to pass.
Too high of a level will cause the audio signal to become choppy and
intermittent. The Squelch level is adjustable from 01 - 99. The higher the
value, the lower the sensitivity.
