> What do you think such a mode would be used for, Bill? The latest brainstorming is a community mesh network. Put a little box in the attic with Ethernet on one side and an antenna on the other. Build a whole VPN with video, vip, whatever.. Given the bits the options are endless. If the price is reasonable many hams in any neighborhood would participate.

Given more RF bits we'd see a lot of the old guard come back to play.. The current 1200/9600/56000 was getting long in the tooth in the mid 90's.

Ultrawide ? Ultra wide is megahertz... 100's of kilohertz is barely getting beyond 90's.. In the real world anyway.
