The
VX-7R
’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.
1.
Press the
key, then press the
MONI
switch on the left
side of the radio. This provides a “Short-cut” to Menu
Item (
Basic Setup #1: SQL NFM
) or Menu Item (
Basic
Setup #2: SQL WFM
).
2.
Now, press the
or
key to set the background noise is just silenced (typically at
a setting of about “3” or “4” on the scale); this is point of maximum sensitivity to weak
signals.
3.
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.
4.
You may also adjust the Squelch setting by using the “Set” (Menu) mode. See page 82
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 (subaudible) CTCSS tone. Or if your friends have radios
equipped with DCS (Digital Coded Squelch) like your
VX-7R
has, try using that mode
for silent monitoring of busy channels.
