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.

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
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.
