QUELCH
A special S-meter Squelch feature is provided on this radio. This feature allows you to set
the squelch so only signals exceeding a certain S-meter level will open the squelch.
To set up the S-meter squelch circuit for operation, use the following procedure:
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 80:
SQSMTR
.
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 select the desired signal strength level
for the squelch threshold (
LVL 1
-
LVL8
or
OFF
).
5.
Press the
PTT
switch to save the new setting and return to normal operation.
1) When the S-meter squelch is activated, the S-meter
segment corresponding to the squelch threshold which
was set by step 4 above will blink.
2) The receiver’s squelch will open based on the higher of the lev-
els set by the two squelch systems (Noise Squelch and S-meter Squelch).
For example:
a) If the Noise Squelch (SQL control) is set so that signals at a level of “S-3” will open
the squelch, but the S-meter Squelch (Set Mode Item 80) is set to “LVL 5,” the squelch
will only open on signals which are “S5” or stronger on the S-meter.
b) If the S-meter Squelch is set to “S3,” but the Noise Squelch is set to a high level which
will only pass signals which are Full Scale on the S-meter, the squelch will only open on
signals which are Full Scale on the S-meter. In this case, the Noise Squelch overrides
the action of the S-meter Squelch.
