Walt and group, My understanding is that the 64QAM mode of the DRM programs being used by SSTV operators does not work well on HF frequencies unless you have near perfect conditions.
What are the opinions on the how well multipath and difficult conditions are handled by these different modulation techniques? Also comparing with QAM and OFDM. 73, Rick, KV9U DuBose Walt Civ AETC CONS/LGCA wrote: >Why not run 64 tones with FSK at 50 baud or 64 tones with OQPSK at 50 baud? > >Shucks, for that matter how about 128 tones using QAM64 at 50 baud? > >Walt/K5YFW > > > Need a Digital mode QSO?
