Dave, To calibrate a frequency counter, you must have an accuracy of 10 times greater than the lowest resolution on the counter. In other words, if your counter reads down to 1 Hz, then you must calibate it to within 1/10th Hz to assure that the last digit is accurate. +/- 1 kHz is just not sufficiently accurate for calibrating a frequency counter that I would want to use at my workbench.
You can calibrate your K2 to within 20 Hz and use the K2 output to calibrate your counter. The K2 calibation can be done with no equipment other than the K2 itself with its counter probe. I do this on a daily basis on K2s that I have in for repair - it works. The method is available on the Elecraft website at http://www.elecraft.com/Apps/K2%20C22%20Adjust%20App%20Note.pdf . 73, Don W3FPR > -----Original Message----- > > I have a couple of frequency counters, and I know they are a little off. > When I went through the alignment the first time, they tell you how to > adjust settings based on zero beating from another transceiver, but I > wanted to calibrate one of these counters well enough to use one of them. > > I have a XG2 that I haven't built yet, and I see that it has a +/- 1khz > accuracy.
