FUNCTIONS FOR RECEIVE
2001 NEW
■ 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.
➥ While M2 is selected with [MENU], push [F5 VSC]
to switch the VSC (Voice Squelch Control) function
ON and OFF.
•“VSC” appears when the function is activated.
•The VSC function activates for phone modes
(SSB, AM and FM).
•The VSC function can also be used for scanning
operation in AM or FM mode (p. 69).
