Sorry, I'm not quite sure — is there a feature request here?
If you're asking about detecting carriers so as to use non-AM demodulators on them, that is the sort of thing that might happen in the future but it will most likely be derived from FFT power measurements (i.e. looking for the same peaks you see on screen) rather than the unselective AM mechanism.
no feature request, just wanted to share some audio from the AM demodulator.
Unselective AM is great! When you have enough dynamic range to hear week signals and strong over the noise floor. Its a great method to monitor ATC radio traffic..
I would suspect that AM will find and acquire a signal, only for baseband reference, then pull the base band chunk into an revolving FM demodulation slots with AGC to rotate around acquired signals.?
