I think the DV part of dstar is somehow a dead-end... The intresting ability of d-star is the high-speed mode in the D1 units. Seems it's capable of something like 80kb/sec, but there is very few info on it. It could be 140khz wide .. does someone have documentation about ?
This data rate allows not only DV, but DAV (Digital Audio Visual). That is live video and sound in very good quality. Only on 1.2 ghz now, but if it's 140khz wide i think 70cm may be an option too. Not only hear, but see your qso partner over the 70cm repeater,would that be intresting? I think yes. Lets hope icom doesent make a proprietary "dead box", but only a modem, and use a PC for codec and camera/display stuff.
