d star may be all ok on paths where it is a perfect signal, but nywhere
that there is QSB or QRM or QRN it is dead in the water and is useless.
And 90% of Amateur radio has those issues to deal with.

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.

I have no doubt some form of voice over data will be the norm someday but I
have doubts that will be D-STAR in it's current form. If it switches to a
non-proprietary protocol ... or the patent on AMBE expires then maybe.
... but Amateur Radio isn't about just buying some vendors latest gadget
like it's the latest iPhone .... it's about experimentation or
more accurately:
> Continuation and extension of the amateur's proven ability to contribute
to the advancement of the radio art.
> Encouragement and improvement of the amateur service through rules which
provide for advancing skills in both the communication and technical phases
of the art.
> Expansion of the existing reservoir within the amateur radio service of
trained operators, technicians, and electronics experts.

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.

I use D-STAR Digital Data on 1.2 GHz for my Winlink RMS Packet CMS
connection, 24/7.
The Pactor 3 mode that I use for Winlink HF forwarding is proprietary.
But nobody else has come up with anything near as good (yet). So a lot
of hams use it because it does the job well.
We use D-STAR DD 1.2 GHz as a backup to the local internet connection
for EMCOMM at the EOC and I do the same at home, too. WebEOC for example.
D-STAR is another tool in the box, another readily available method that
might be better in a particular circumstance. Why limit myself by not
having a set of metric sockets for my wrench?
But to the subject how about some D-STAR DD on the satellites? You
would need to figure out a way around the L-band downlink e.g. a receive
converter from another band or something...
Maybe not necessarily (easily) feasible but nonetheless perhaps a
thought path to other digital ideas for satellites. Both data and voice.
These are just more fun things to think about!
By the way, did you know that the MCU on the Fox-1 satellite is
proprietary? ;-)

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.
