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 capa-
bility typically are shown, on navigation charts, with
the voice calling frequency in parenthesis above the
navigation frequency.
