The
VX-6E
’s Squelch system allows you to mute the background noise when no signal is
being received. Not only does the Squelch system make “standby” operation more pleas-
ant, it also significantly reduces battery current consumption.
The Squelch system may be adjusted independently for the FM and Wide-FM (FM Broad-
cast) modes. AM utilizes the setting chosen for FM.
1. Press the [
F/W
] key, then press the [
0
(
SET
)] key to enter the Set mode.
2. Rotate the
DIAL
knob to select Set Mode Item 58:

3. Now, rotate the
DIAL
knob to set the Squelch so that the background noise is just
silenced (typically at a setting of about “

for Wide-FM); this is point of maximum sensitivity to weak signals.
4. When you are satisfied with the Squelch threshold setting, press the
PTT
key momen-
tarily to save the new setting and exit to normal operation.
1) A special “RF Squelch” feature is provided on the VX-6E. This feature
allows you to set the squelch so that only signals exceeding a certain S-meter
level will open the squelch. See page 23 for details.
2) If you’re operating in an area of high RF pollution, you may need to consider “Tone
Squelch” operation using the built-in CTCSS Decoder. This feature will keep your ra-
dio quiet until a call is received from a station sending a carrier which contains a matching
(subaudible) CTCSS tone. Or, if your friends have radios equipped with DCS (Digital
Coded Squelch) like your VX-6E has, try using that mode for silent monitoring of busy
channels.
