Fellas:

There is NO(!) means of significantly re-calibrating the keyer 
speed... and it should not be off by nearly THAT much.

The Keyer speed control IS a POT... the ONLY encoder is the VFO knob.

C22 is the master oscillator calibration capacitor which sets the 
calibration for the entire K2. If you adjust C22, you will HAVE to 
re-run CAL PLL, and then you will probably want to re-run CAL FIL for 
each of your XTAL filter settings.

REGARDLESS if the setting of C22, it will NOT significantly effect 
the speed calibration of the internal keyer.  Adjust C22 only if the 
frequency calibration of the K2 is not to your satisfaction. I can 
provide documentation for an improved calibration routine... 
available on the Elecraft web site, but I don't recall precisely 
where it is located.
