What about an half duplex split and an full duplex split. Maybe even
automatically choose beetween them. (ie rig can full duplex and the frequencies are
on 2 different bands --> switch do satmode if available). In fact, the
satmode is nothing elso than split, but not using VFO_A and VFO_B but VFO_A und
VFO_C (sub)

Is it really that different from other rigs. I could imagine, that the
TS2000 and FT847 are similar.

BTW. you got the patch for the IC910 i sent to you directly?
