I cannot address you by name or call, but greetings none the less (possibly you are Tom?):
I just uploaded a Youtube demo of the procedure that I use to calibrate the K3 on WWV at 10 MHz. In the demo I start off with a nominal 6 Hz error and show how I make use of the toggle between CW-NORMAL and CW-REVERSE to judge when I am exactly zero beat. It is a matter of judging when the tones heard from the WWV carrier (*not* the modulated tones they have on the carrier) are equal as I switch between CW-NOR and CW-REV using the MODE-->ALT function to toggle back and forth. Since I was 6 Hz high, I turned the REF CAL frequency *down* from 49.379.780 to 49.379.756 (24 Hz) to accomplish the calibration adjustment. Your exact frequency will of course not be the same as mine. I do not know if this will be sufficiently clear in the demo, but I find it works very well for me. When I did this 3 months ago, my starting error was 25 Hz high. Since calibrating it to 0 Hz error at that time, I have "drifted" only 6 Hz. Not bad at all (no high stability option installed here). The demo is hopefully found at this link: http://www.youtube.com/watch?v=_SWRlTUG5RM 73, Chuck, W5UXH Las Cruces, NM tomb18 wrote: > > Hi, > > I just finished my kit and I seem to have some difficulty determining if > the ref. osc. is calibrated correctly.
