Those dashes sound a little long. The formula normally used to calculate
lengths of elements is
dot length (msec) equals 1200 divided by wpm.
Thus, at 22 wpm, the dot length should be 54.5 msec. Dashes are normally
three times as long, i.e., 163.5 msec.

Is it possible to have a speed step of .5 in between the present CW speed

I am particularly looking for a CW speed of 21.5 wpm just now.
Charles, I doubt that the tolerance of the K3 displayed speed is better
than +/- 0.5wpm, so you may find that 21 or 22wpm could be just the
speed you are looking for. Have you measured it accurately? Your
findings would be of interest here.

I measured the sidetone dah lengths at the speaker:
A 22wpm dah is 0.207 sec; a 21wpm dah is 0.219 sec. Not sure about the
conversion to wpm but I think this comes out to 24 wpm and 22.8 wpm
respectively; could be wrong.
