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 and you figure the difference between the two frequencies and divide by 2. Then the procedure has you adjust C22 using this result and re-run CAL PLL. This brought 10 MHz WWV's frequency readout to within 10 Hz on my K2's dial. I may be a bit off on this procedure (I'm writing this from memory), but the procedure is in the manual, and it works! 73, de Earl, K6SE _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
