Part of the "need for speed" is technical innovation, part of the ARS. The current digital techniques do not come anywhere close to the Shannon-Hartley limit. There are those of us who are working on this.
Attaining this goal would improve spectrum usage for all modes of operation on the bands. Part of the motivation is to replace the modems designed for commercial usage.

I'm curious as to why the need for speed is driving some folks when it comes to amateur to amateur communication. Perhaps someone can explain it to me. It appears obvious from Rick's comment that a lot of amateur radio software developers seem to get more kicks out of working on lower speed, low snr protocols. I also keep seeing the "need for speed" touted as technical innovation when in reality it is using off the shelf commercially produced modems. Where's the innovation that a bandwidth limit is going to stop? Is it just that it will keep us from using faster commercially produced modems? Jim WA0LYK
