Split Operation
The split operation feature allows you to transmit a call
to a Flight Service Station using the COM band frequen-
cies, while receiving a VOR station (in the NAV band).
VOR stations equipped with this capability typically are
shown, on navigation charts, with the voice calling fre-
quency in parenthesis above the navigation frequency.
Programming a Transmit Frequency
Press downward on the
VOLUME
knob
, repeatedly
if necessary, to select the VFO mode.
Set a NAV band (108.000 - 117.975 MHz) frequen-
cy using the
DIAL
selector knob or keypad.
Press the
[
F
]
key momentarily, then press the
[
MW
(
SPL-W
)]
key. The “ ” icon will blink, and the
transmit frequency will appear on the display.
Now set your radio’s transmit frequency, where the
Flight Service Station will be listening for calls, us-
ing the
DIAL
selector knob or keypad.
Press and hold in the
[
MW

key for 2 sec-
onds to save the transmit frequency and return to the
NAV band frequency.

quency, but you have not yet activated the split-frequen-
cy function; go on to the next section.
