The
VX-3R/E
’s Squelch system allows you to mute the background noise when no signal
is being received. The Squelch system make “standby” operation more pleasant, and sig-
nificantly reduces battery current consumption.
The Squelch system may be adjusted independently for the FM and Wide-FM (FM Broad-
cast) modes.
1.
Press and hold in the [
TXPO
] key for one second to enter the Set mode.
2.
Rotate the
DIAL
knob to select Set Mode Item 78:
SQ LVL
.
Note
: Do not forget to pull the
DIAL
knob to rotate the
DIAL
knob.
3.
Press the [
TXPO
] key momentarily to enable adjustment of this
Item.
4.
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 AM/FM, and “
2
” or “
3
” for Wide-FM/FM Broadcast/AM Broadcast). This is the
point of maximum sensitivity to weak signals.
Note
: Do not forget to pull the
DIAL
knob to rotate the
DIAL
knob.
5.
When you are satisfied with the Squelch threshold setting, press the
PTT
switch mo-
mentarily to save the new setting and exit to normal operation.
1) The VX-3R/E can set the squelch threshold level on the AM mode, FM
mode, Wide FM mode, and AM Broadcast individually.
2) A special “S-meter Squelch” feature is provided on the VX-3R/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 22 for details.
3) 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-3R/E has, try using that mode for silent monitoring of
busy channels.
