Section 2-19 “AM/FM/SSB Demodulation” on page 2-26

for a description of the

built-in demodulator.

Press one of these submenu keys to select an AM/FM demodulation type.
The red circle indicates the active selection. This menu provides five
choices for the type of signal to be demodulated.

FM Wide Band:

Frequency Modulation

FM Narrow Band:

Frequency Modulation

AM:

Amplitude Modulation

USB:

Upper Sideband. This can also be used when demodulating CW

(Morse code) signals.

LSB:

Lower Sideband. This can also be used when demodulating CW

(Morse code) signals.
