Pilot tone squelch
The ew 500 G2 transmitters add a 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 pilot tone, 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 transmitters are switched off.
In order to benefit from this feature, the pilot tone function must be activated
on both the transmitter and the receiver. The receiver’s pilot tone function is
factory-preset to “ON” (= activated).
Field strength-dependent squelch
Depending on the strength of the received RF signal, the receiver’s audio
output is opened or muted. Via the “
Squelch
” menu of the receiver, the
squelch threshold can be adjusted in three steps
(Low, Mid, High).
