C22 doesn't control the dial calibration, it only controls the frequency 
counter used in the dial calibration.  Once you've done the calibration, 
including filters, you could actually turn C22 to end stop without 
compromising the calibration.

Whilst the frequency counter is slightly off, you can work out how much 
to over/under-correct, and therefore considerably reduce the number of 
iterations.  It's sufficiently long since I did this that I cannot 
remember the exact details.
