This code uses librtlsdr for a basis, and I have created an AM/FM/WBFM/SSB receiver application with this stuff. I call the application radioDiags. The application sends demodulated data to stdout as raw PCM formtted as signed 16-bit little endian integers to stdout at a rate of 8000S/s.

I hate to use global variables, but this gives me a realtime view (al… #40
of the hardware setting of the IF gain. There was a race condition if the user changed the IF gain through the user interface, such that the AGC was not aware of this change. Under some conditions, I saw data consisconstnacy between the AGC's notion of the IF gain and the hardware setting of the IF gain. I'll beat on this code before I decide to merge this branch into master. Once I prove that this works, I'll make the same changes (almost) into my HackRF diags.
