Isn't our mission one of experimentation? What, exactly, is wrong with
utilizing, with the proper power and bandwidth limitations, part of a
transponder passband for non-SSB/CW modulation?
Yes, there are considerations regarding AO-7, but that is a problem we
face using any mode on that satellite. CW signals routinely modulate the
SSB voice signals, unless operators take care to restrict uplink ERP to
the minimum necessary for a QSO.
Modes like Olivia, which has FEC and can track frequency changes
(Doppler or otherwise), should be easily workable over satellite, and
may not need to be much above the noise floor.
Ron may have been running a bit too much uplink ERP, but I don't think
he needs to be beaten over the head for doing what Amateur Radio is all
