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 all the frequencies. That's because all you are doing by adjusting C22 is to calibrate the frequency counter that is used for setting everything else! If you had you filters set to your satisfaction, all you have to do is to force the K2 to re-read the BFO frequencies after you've finished with C22. You do that by connecting the probe to your BFO test point, enabling CAL FIL, then, for each filter and bandwidth, change the setting away from what you had, then move it right back. The fact that you twiddled the dial causes the K2 to "think" you changed things, even though you put it right back. So then it'll re-read and store the BFO frequency using the newly-calibrated frequency counter function (Cal Fctr) to give you better dial readings. Ron AC7AC -----Original Message----- I used Wayne Burdick's article to calibrate my K2. When I first tuned in WWV, the zero beat was at 9999.5. I adjusted c22 & measured TP1(VCO) & TP2(BFO) until the two test points matched. Now WWV zero beats at 10000.5 . Should I have set my dial to 10000.00 & then adjusted C22?. I have also checked my calibration with my ICOM 756Pro &it also shows that I am off 500HZ based on WWV & other signals on 20 meters.
