Hi Bartek, I suggest you try W3FPR's dial calibration method if you have not done so already. You can find it at Don's web page http://w3fpr.com/ under the left side menu, "Setting the K2 Dial Calibration." If you only adjust C22 and do not run CAL FCTR, CAL BFO, and CAL FIL as described by N6KR and W3FPR, you will not have reset the stored DAC values from which the actual frequency display is computed.
I finally tried Don's method this past summer after using my K2 for nearly 4 years -- it made a huge difference from my initial hasty calibration in the excitement of putting the rig on the air for the first time! 73, Mike, K8CN -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-cannot-calibrate-dial-tp7366847p7366886.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
