Thanks for all the suggestions!?? I plan to give some a try.? I agree that setting alignment is not trivial.? I also agree that CW seems OK.? Tuning around, the BW seems near what I would expect for SSB filtering and distortion is minimal.? My scratch built SSB rigs were really easy by comparison.
The "pinched" SSB audio is an annoyance, but not a show-stopper. The need to be dead-on frequency for decent SSB is more of an issue.? When listening to QSOs, the symptom is apparent - If tuned for good audio on station 1, and station 2 is just a bit off freq, it is hard to understand.? ...It is that critical.? Possibly a result of the filter's narrow bandwith / center position?? More tweaking may help.? I have a broadband RF noise generator (homebrew, of course) and PC audio spectrum analyzer used to align my Elecraft K2.? May give that a try.?? The BFO adjustment is a pain.? There is some, but not much change with lots of encoder spinning.? Wonder if I will wear out the encoder before it is done. ;)
Best I can tell, my TX audio is OK, but hard to tell exactly when listening to myself.? No on-air tests yet.
An AGC is also on my agenda, have Axicom relays and replacement inductors, but want to get the board functioning as well as possible before jumping in with modifications.
Have archived the replies and the testing continues...
