Operation
To set up the RF squelch circuit for operation, use the following procedure:
(1) Press and hold in the
[
MHz
]
key for one second, then rotate the
Main Dial
knob to
select “
22 RFSQL
.”
(2) Press the
[
MHz
]
key momentarily, then rotate the
Main Dial
knob to select the de-
sired signal strength level for the squelch threshold (
OFF
,
S-3
,
S-5
,
S-7
,
S-9
, or
S-
FULL
).
(3) Press and hold in the
[
MHz
]
key for one second to save the new setting and exit to
normal operation.
Note: The receiver’s squelch will open based on the highest level set by the two squelch
systems (Noise Squelch and RF Squelch). For example:
(1) If the Noise Squelch (Menu #28) is set so that signals at a level of S-3 will open the
squelch, but the RF Squelch (Menu #22) is set to “
S-9
,” the squelch will only open on
signals which are S-9 or stronger on the S-meter.
(2) If the RF Squelch is set to “
S-3
,” 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 RF Squelch.
