Channel Step Selection

You can set channel steps, 5 kHz - 100 kHz or Auto, in Manual mode or Chain search
mode. The default receive mode should be the proper mode setting in almost all cases. You
may wish to set some VHF channels for NFM mode, depending on any adjacent channel
interference problems. Note that WFM is typically only used for broadcast frequencies, such
as TV audio or FM radio.

See “STEPS” in Menu Description for details.

Receiving Mode Selection

You can also set the receiving mode, AM or FM etc., in Manual mode or Chain search mode.

See “MODE” in Menu Description for details.
