I am interested in homebrew (practical, not theoretical) digital component
decoding/demodulation of RF carriers -- in other words, a digitally based
receiver. This seems well within the reach of off-the-shelf micros for the
frequencies used by long-wave carriers (commercial AM, WWVB, 160-190KHz
"lowfers"). A fully digital receiver has potential for custom features,
digital filtering schemes and small size and the "inner loop" software seems
relatively straight-forward (no software FFT is needed as only one carrier
frequency is of interest). Anyone out there with similar inclinations?
