I Voice squelch control function

This function is useful when you don't want unmodu-
lated signals. When the voice squelch control function
is activated, the receiver 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 components does
not change within 1 sec., squelch closes.
