BASIC OPERATION
DSelecting the receive mode
Receive modes are determined by the
physical properties of the radio signals.
The transceiver has 3 receive modes:
FM, AM and WFM modes. Typically, AM
mode is used for the avionics band
(108–135.995 MHz) and WFM is used
for FM broadcast stations
(76–107.995 MHz).
When pushing [PTT], a beep tone
sounds indicating the mode is not
FM mode. The transceiver cannot
transmit in AM or WFM mode.
