Hi Bob,
several months (and revisions) earlier, I performed detailed
measurements and found that quality of transmitted CW greatly
varied with code speed, time between characters/words and
especially with rig temperature.
Didn't have time to retest with current revisions,
but from your results I'd guess that some of the
instability is still there.
