Squelch
Pilot tone squelch
The transmitter 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).
