Receive mode selection

Receive modes are determined by the physical properties of

 

the radio signals. The receiver has 3 receive modes: FM, AM

 

and WFM modes. The mode selection is stored indepen-

dently in each band and memory channels.

Typically, 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).
