I had been using 650 Hz for awhile but decided to go to 800 Hz for
some reason. It just sounds better to me now. Maybe becuase I got used
to it while using my code practice program; higher pitch seems to
sound better for QRQ.
I was thinking of doing a bunch of filter alignments at sidetone
pitches 50 Hz apart, just to tabulate the filter settings. If you
recorded them all it wouldn't take very long to reprogram them when
you want to change sidetone pitch. It's only 4 three-digit DAC
numbers to dial in (or 8 if you want CW Rev). You could probably
change filters in a minute or so.
I was wondering, is there an electically optimal sidetone pitch which
the K2 prefers?
