Yes,
It could work as long as software for doppler control (eg SatPc32) can invoke the smaller frequency changes which it actually can (see my other note on the IC-9100). So you would use the built-in DSTAR module for uplink or downlink and the 9600 packet mode with a GMSK node adapter for the other in a full duple radio like the IC-9100. Or you use two radios in 9600 packet mode with 2 node adapters for uplink and downlink as long as they are supported via doppler software and small frequency steps.

When GO32 was running, we were able to send and receive data at 9600 bps. DSTAR voice. on 444 is 2400bps and data is 4800bps gsm if I am correct.
So, why would it not work via satellite other than having to get 5 kc steps reduced to 1k or less.

Well back in the days of AM and when SSB came out it was the same thinking then BUT what has happened to AM . Same thing with DSTAR it is growing and will grow . Thats what makes ham radio so much fun, there is something for everyone 73,s Damon
But the difference there is that *anyone* can make an SSB rig. Only one manufacturer is allowed to make AMBE codecs, and they will only sell to a handful of approved radio manufacturers.
It is illegal to make your own DStar radio, without buying the AMBE codec from DVSI. That sort of thing has no place in amateur radio.
