The
VX-8GR/GE
’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.
1.
On the
VX-8GR
, press the
f
key, then press the
e
key on the left side of the radio. This provides a “Short-
cut” to Set Mode Item
85: SQL LEVEL
.
On the
VX-8GE
, press and hold the
m
key for one
second to enter the Set Mode, rotate the
DIAL
knob to
select Set Mode Item
85: SQL LEVEL
., then press the
m
key briefly to enable selection of this Menu Item.
2.
Now, rotate the
DIAL
knob to the point where the back-
ground noise is just silenced (typically at a setting of about
“3” or “4” on the scale); this is the point of maximum sen-
sitivity to weak signals.
3.
When you are satisfied with the Squelch threshold setting, press the
PTT
key briefly
to save the new setting and exit to normal operation.
4.
You may also adjust the Squelch setting by using the “Set” (Menu) mode. See page
143 for details.
1) The Squelch level may be set on the “Main” and “Sub” bands separately.
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 (sub audible) CTCSS tone. Or if your friends have radios
equipped with DCS (Digital Coded Squelch) like your
VX-8GR/GE
, try using that mode
for silent monitoring of busy channels.
