Fred, I missed your first post, but have you checked the procedure for setting C22 on the Elecraft web site (www.elecraft.com). It's under "Builder Resource Page", then click on "How to "Build and Test Your Kit" under "Main Topics" of the page, then click on, "Adjusting C22 to calibrate the K2's Frequency Display".
This procedure provides calibration as accurate as the K2 is capable of based in the accuracy of the source. If you can hear WWV, it will be as close as the K2's logic and WWV. You can't do better than that with any test equipment, it's very simple and straightforward to do and requires no external equipment whatsoever.
