FUNCTIONS FOR RECEIVE

Voice squelch control function

This function is useful when you don't want to hear unmodulated signals. When the voice squelch control function is activated, the transceiver checks received signals for voice components.

If a receiver signal includes voice components, and the tone of the voice components changes within 1 sec., squelch opens. If the received signal includes no voice components or the tone of the voice compo- nents does not change within 1 sec., squelch closes.
