Split Operation
The split operation feature allows you to transmit a call to
a Flight Service Station using the COM band frequencies,
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 frequency in
parenthesis above the navigation frequency.
Press the key, repeatedly if necessary, to select
the VFO mode.
Set the desired VOR station’s frequencies in the NAV
band (108.000 - 117.975 MHz) using the
DIAL selec-
tor knob or keypad.
Press the key followed by the key. The “ ”
icon will blink, and the transmit frequency will ap-
pear on the display.
Now set your radio’s transmit frequency, where the
Flight Service Station will be listening for calls, using
the
DIAL
selector knob or keypad.
Press and hold in the key for 2 seconds to save
the transmit frequency and return to the NAV band
frequency.
Press and hold in the PTT switch to transmit on the
split transmit frequency.
Release the PTT switch to return to the receive mode.
To disable the “Split” function, set the receiving fre-
quency to any frequency outside of the NAV band (the
“
” icon will disappear).
Note : A split frequency can be programmed into each
memory channel independently. Set a transmit frequency
before programming the memory channel, if desired. The
split function on/off setting can also be programmed into
a memory channel.
