FREQ

setting the squelch and sidetone levels, only the
frequencies 118.000, 127.000, and 136.975 MHz can be

SPACING
Selection Description
25.0 kHz
Selects traditional 25 kilohertz spacing (760 channel).
8.33 kHz
Selects 8.33 kilohertz channel spacing, which is required in some areas of the
world.
CAUTION
8.33 kHz channels are not authorized for use in the United States.
SQ 250
Sets the squelch threshold for 25 kHz channel spacing operation. May be set to any value between 0 (zero)
and 63. The higher the number, the less signal is required to break squelch.
NOTE
For GNS 430 units with serial number 200 or lower, the operation of the SQ 250 setting is reversed. The
higher the SQ 250 number, the more signal is required to break squelch.
SQ 833
Sets the squelch threshold for 8.33 kHz channel spacing operation. May be set to any value between 0
(zero) and 63. The higher the number, the more signal is required to break squelch.
SIDE
Sets the sidetone audio output level. May be set to any value between 0 (zero) and 63.
MIC
Sets the Mic Gain output level. May be set to any value between 0 (zero) and 63. This adjusts the output
for differences in microphones used. Should adjustment be necessary refer to the maintenance manual.
This Mic Gain software adjustment is effective for GNS 430 s/n 97107371 and above, and GNC 420 s/n
97202086 and above.
NOTE
The sidetone audio output level is independent of the COM volume knob on the 400 Series unit.
