Setting the Squelch

Adjust VOLUME to a comfortable listening level.

Auto Squelch

AUTO is a compromise between tight
and threshold.  It is a convenience for
listening to stronger signals.

➪

Note:  Be sure that the Squelch control

clicks into the AUTO position.

Manual Squelch

To manually set the Squelch, you must
be in the Manual Mode.
No signal should be present when
adjusting squelch.
Press 

M

 until you do not hear

a signal.

Turn until hiss heard.
This lowers the “squelch gate,” allowing
all signals and noise to get through.

Turn just until hiss stops.
This raises the “squelch gate” allowing
only strong signals to get through.
