I was just wondering... with all the excitment that the shortwave
(listening) community seems to be having down on HF with digital radio
Mondiale (DRM), have people been experimenting with similar digital voice
encoding/decoding on 2m? It seems as though DRM-style radio would pass
through many current repeaters without difficulty (being spectrally
efficient) and be especially valuable in handitalkies that don't yet
typically have DSP processing to clean up the audio.
