I think setups using GMSK modems or a DV-RPTR board and an all mode 
radio with Doppler correction will have the most success on satellite 
D-STAR, because computer Doppler compensation and the small tuning step 
size will keep everything within tolerance.  Time to pull my DV-RPTR 
board out and hook it up to the IC-7000. :)
