Receive mode selection
The receiver has three receive modes, FM, AM and WFM.
The mode selection is independently stored in each band
and memory channels.
Typically, the AM mode is used for the AM broadcast stations
(0.495–1.620 MHz) and air band (118–135.995 MHz), and
WFM is used for FM broadcast stations (76–107.9 MHz).
