As preface, I'm not a radio engineer. I'm a software guy with
pretentions to understanding digital hardware. I have a few signal
processing books on a dusty shelf. You lose me as soon as you start
talking Q signals.
The Odyssey board operates at 10MHz IF; so wouldn't it need an external
tuner?

Have you looked at all at the Siren board? It's part of the HPSDR and
Suitsat II projects: a low-power, low-cost SDR engine using the dsPIC33F
embedded controller from Microchip. The current design uses 10 MHz RF in and
out, and the QSD and QSE for complex sampling and excitation. There

My first thought is to just increase the sample rate and effective
bits per sample of the audio processing hardware, and increase the
number of channels so that ordinary stereo audio can happen
simultaneously with analog I/O. I think it's a crime that cheap
