We've explored the theoretical limits of HF DV which are around -13dB SNR in a 3000Hz noise BW:
http://www.rowetel.com/?p=4053 So, SSB can be improved upon - the problem is one of engineering rather than any fundamental limit. Along the way there will be much "Research and Disappointment". But it wouldn't be an interesting problem if it was easy. - David On 08/02/17 08:37, Bruce Perens wrote: > Glenn, I meant that it's easy for us to work on HF, because we don't > have to modify the radios and can get non-wizard operators involved > easily.
