Squelch

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).
