I don't believe that this web-page has been noted on amsat-bb


Besides pointing out some serious problems with using the proprietary
codec that is currently built into DStar, it has  the great idea of
hacking out the digital voice daughterboard in an ICOM DSTAR radio and
plopping in a replacement that implements a free codec.

I wonder how complicated it would be to integrate a digital repeater a
SDX linear transponder bandpass to operate as a suitable digital voice
channel or two. If the SDX on board nextgen will be programmable on
the fly, it's something we could work on on the ground and try in
flight later on.
