Thanks. That's helpful. Like I said, this happens to be an area in which I'm particularly interested. Actually, I'm aware of the G4GUO's work. Is there a group or a website that discusses people's real-world experience with this protocol? I was under the impression that it needed a pretty high signal to noise ration to make it work well. I'm also aware of ANDVT. So, yes, you're quite right: There ARE at least two examples of digital voice in 3KHz on HF. As I didn't state my original point well, let me try again: Doing digital voice on HF in 3KHz bandwidth is tough. Forcing us to START experimenting with digital voice on HF in a 3KHz restricted bandwidth is a pretty steep wall to climb. Sort of like starting out learning how to walk by running. I personally have no HF digital experience. But I know a bit about both data compression and digital communications protocols. As a software/firmware guy, I think this area has a lot of promise if it's not stifled by overly restrictive regulation. de K1PGV Need a Digital mode QSO?
