D Voice squelch control (VSC)
This function is useful when you don’t want unmodulated
signals pausing a scan. When the voice squelch control
function is activated, the receiver checks received signals
for voice components. If a received signal includes voice
components, and the tone of the voice components changes
within 1 second, the scan pauses (or stops). If the received
signal includes no voice components, or the tone of the
voice components does not change within 1 second, the
scan resumes. (default: OFF)
