I just would like to put this thread back onto its tracks..... The
problem is with CW (although SSB does suffer too) and the main problem
is that I can hear the 3rd harmonic which when mixed with the
fundamental makes a rough note on CW especially when tuning away going
up in frequency.
Combining third and fundamental, at AF, should not produce a rough note.
It should produce a string-like tone rather than the flute-like done
from just the fundamental.
If you are getting any low frequency beat, it means the signals are not
harmonically related.
(I think you would need an awful lot of third harmonic to shift much
from flute to string.)
