First of all, let me apologize for any disruption I may have caused by my tests (experiment, interference, ...).
To all,
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 about: experimentation.
