Squelch
Pilot tone squelch
When the transmitter is set to stereo operation, it adds a 19-kHz pilot tone
to the audio signal. The receiver checks incoming audio signals to see if the
pilot tone is present. In the absence of the 19-kHz signal, the receiver’s audio
output will remain muted, even if a strong RF signal is present.
This prevents strong interfering signals from causing hissing noise in the
receiver when the transmitter is switched off.
Field strength-dependent squelch
Depending on the strength of the received RF signal, the receiver’s audio
output is opened or muted. Via the “
SQELCH
” menu of the receiver, the
squelch threshold can be adjusted in three steps
 
(LO, MID, HI).
