RF S
QUELCH
A special RF Squelch feature is provided on this radio. This feature allows you to set the
squelch so that only signals exceeding a certain S-meter level will open the squelch.
To set up the RF squelch circuit for operation, use the following procedure:
1.
Press and hold in the [
H/L
] key for one second to enter the Set mode.
2.
Rotate the
DIAL
knob to select Set Mode Item 32:
RF SQL
.
3.
Press the [
H/L
] key momentarily to enable adjustment of this Item.
4.
Rotate the
DIAL
knob to select the desired signal strength level for the squelch thresh-
old (
S1
,
S2
,
S3
,
S4
,
S5
,
S6
,
S8
,
S9+
, or
OFF
).
5.
Press the
PTT
key to save the new setting and return to normal operation.
The receiver’s squelch will open based on the higher of the levels set by the two squelch
systems (Noise Squelch and RF Squelch).
For example:
1) If the Noise Squelch (SQL control) is set so that signals at a level of S-3 will open the
squelch, but the RF Squelch (Set Mode Item 32) is set to “
S5
,” the squelch will only
open on signals which are “S-5” or stronger on the S-meter.
2) If the RF 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 RF Squelch.
