How to select Analog Demod (Metrics)
Analog demodulation can demodulate AM DSB, AM SSB, FM, FM Stereo /
RDS, PM signals. Under analog demodulation metrics the following
information is reported for each signal type: Carrier power, modulation rate,
SINAD, THD, plus deviation, depth, or RMS depending on the signal. Metrics
also displays the demodulated signal and the audio frequency spectrum.

IMPORTANT! The FieldFox contains only one speaker that supports mono
audio output (i.e., if you play a stereo WAVE file, the Left and Right
channels are output in mono audio). If you want to output a stereo WAVE
file in stereo (to hear the left and right channels separately on the FieldFox)
you have to use the headphone jack and stereo headphones (i.e., most
earbuds, headphones, etcetera support stereo). Learn more, see also
