Last night I redid my C22 reference oscillator adjustment using WWV on 10mhz as the zero beat reference. This is the third time I have adjusted C22 and each time I am able to adjust C22 to a precise offset balancing TP1 and TP2. However, when I put the cover back on the K2/100 I find that WWV zero beats a few tens of hz off. (After last night's adjustment, the zero beat was 10000.03) One should expect to be +- 10 hz as that is the finest resolution of the VCO, but it would be nice to get a little closer.
The unit was thoroughly warmed before adjustment although there may be some temperature difference between having the cover on and having the cover off. This is hardly a big deal, but I wonder whether others manage to get an exact setting or whether this is a process that you repeat until you finally nail the adjustment. HOWARD W.
