SQL S-
METER
A special SQL (Squelch) S-meter 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 feature for operation, use the following procedure:
1.
Press and hold the
m
key for one second to enter the Set Mode.
2. Rotate the
DIAL
knob to select Set Mode Item 86: SQL S-
METER .
3. Press the
m
key briefly to enable selection of this Set
Mode Item.
4. Rotate the
DIAL
knob to select the desired signal strength
level for the squelch threshold (
LEVEL1
-
LEVEL9
or
OFF
).
5. When you have made your choice, press the
PTT
switch to
save the new setting and return to normal operation.
1) When the SQL S-meter 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 levels set by the
Noise Squelch or the S-meter Squelch system.
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 SQL S-meter (Set Mode Item 93) is set to “LEVEL 5,” the squelch
will only open on signals which are “S5” or stronger on the S-meter.
b) If the SQL S-meter 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.
