It appears that stations attempting to work D-Star via
satellite would need to use two radios.  This was the
case a few years ago, when AA4RC and N3UC were able to
make a brief QSO on AO-27.  You can read about what gear
the used, along with some useful tips for trying D-Star
via satellite, at:


The 5 kHz tuning steps for D-Star radios would make
satellite operating difficult as you mentioned.  AO-27
was the ideal satellite for this sort of experiment,
since its uplink receiver was intended for use with
data, and doesn't filter the lower end of the audio
range that it hears.  Plus the control operators of
AO-27 have stated clearly that they support and
encourage D-Star on AO-27, something not seen for any
of our other satellites.

>From a quick read of the IC-9100 instruction manual, it
is clear that D-Star was not intended to be used in this
radio for satellite operating or for anything other than
the "normal" D-Star operations (RX and TX in the same
band, simplex or repeater).  You could use the IC-9100 as
one of the two radios for D-Star satellite operation as
those guys did for AO-27 a few years ago, but you would
not have access to the IC-9100 satellite functionality.
