SWD
: Audio Output Mute
indicates that the audio outputs are muted (=1); only when the demodulator is selected as
audio source. This would be the case during standard search or no signal found.
: AM selected
indicates if the AM input (MIN) has been selected (=1); normally used for system L.
: Switch Dematrix Mode
