Did you re-run CAL PLL and CAL FIL?
I used Wayne's procedure and found it very easy and it produced frequency
readouts well within the K2's DAC resolution - dead on at most points,
always with 20 Hz, and no other equipment required.
But you MUST run CAL PLL and also CAL FIL afterward to reset a

Bob, Earl and folks,
Earl's comments are correct, but CAL FIL must also be run before calibration
is complete. Each BFO must be changed by at least one 'notch' and moved
back to the same frequency (aqssuming the filters were properly set before).
The K2 must detect that each BFO has been changed
As I recall, after I built my K2 (more than three years ago), after the
first CAL PLL I was unhappy with its frequency dial accuracy ( it was 300
or 400 Hz of on 10 MHz WWV.
There are three different described in the K2 manual for adjusting C22.
I then used the one that measures two frequencies a

500 Hz is a big error. You can get it much cl
