Communicating using the
GNS 530W
The GNS 530W features a digitally-tuned VHF
COM radio that provides a seamless transition from
communication to navigation. The GNS 530W’s
COM radio operates in the aviation voice band, from
118.000 to 136.975 MHz, in 25 kHz steps (default).
For European operations, a COM radio configuration
of 8.33 kHz steps is also provided.
“TX” appears at the upper right corner of the
COM window while transmitting.
Volume
COM radio volume is adjusted using the
COM
power/volume knob
. Turn the
COM power/volume
knob
clockwise to increase volume, or counterclock-
wise to decrease volume.
Squelch
The COM radio features an automatic squelch to
reject many localized noise sources. You may override
the squelch function by pressing the
COM power/
volume
knob. This facilitates listening to a distant sta-
tion or setting the desired volume level.
While receiving a station, an “RX” indication
appears in the upper right corner of the COM
window — to the immediate right of “COM”. A “TX”
indication appears at this location while you are trans-
mitting.
Press the COM power/volume knob momen-
tarily to override the automatic squelch.
Note the “RX” receive indication when
receiving a station.
To override the automatic squelch, press the
COM power/volume
knob momentarily. Press
COM
power/volume
knob again to return to automatic
squelch operation.
