Last I knew, FM was actively discouraged on VO-52 except by hams in countries which only allowed FM in the satellite sub-band.

Hi All,
I'm wondering if the GMSK modulation scheme in D-Star can be inverted and whether the Icom 91AD dualband HT can work full duplex for satellite work. D-Star uses a 6.25kc channel which is way better than the 15kc needed for standard FM but not as friendly as SSB and CW. Let me know. I haven't purchased this equipment but it's worth at least a debate.
