VX-6R/E OPERATING MANUAL 13
OPERATION
SQUELCH ADJUSTMENT
The VX-6R/E’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
pleasant, 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. On the VX-6R, press the
[
F/W
]
key, then press the MONI/T.CALL switch on the left
side of the radio. This provides a “Short-cut” to Set Mode Item 59: SQL.
On the VX-6E, press the
[
F/W
]
key, then press the
[
0
(
SET
)]
key. Rotate the DIAL
knob to select Set Mode Item 59: SQL, then press the
[
0
(
SET
)]
key.
3. Now, rotate the DIAL knob to set the Squelch so that the background noise is just
silenced (typically at a setting of about “1” or “2” for FM and AM, and “2” or “3” 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-6R/E. 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 radio
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-6R/E has, try using that mode for silent monitoring of busy
channels.
