[Elecraft] WWV tones and CW reverse?

[W3FPR - Don Wilhelm]

Bill,

200 Hz calibration error is quite a bit IMHO - but each to his own.
Just so folks don't develop a wrong impression, I usually expect less than 
50 Hz error with nothing more than a quick check of the 4 MHz reference by 
comparing the TP3 output using an external counter and the internal CAL FCTR 
(both measuring the TP3 frequency)- just turn the capacitor until both 
counter read the same.

Then after everything is built, I fine tune using the N6KR method with 
Spectrogram as my guide to properly hearing the 500 and 600 Hz tones that 
WWV transmits.  I expect less than 20 Hz error after completing that (if 
your results are not that good, my first question is 'Did you do CAL PLL and 
also run CAL FIL to write new BFO values?, and were you certain of WWV 
zero-beat?'

73,
Don W3FPR
