"I tune to 10,000,002 and adjust REF CAL for 20 beats in 10 seconds, or as close to 20 as I can get, with the granularity of the ref cal steps." Zero beat has only one solution. Doesn't your method have two solutions, only one of which is correct? 73, Andy, k3wyc

Re: [Elecraft] Frequency Accuracy and stability

Lou, I find that viewing the output on an audio spectrum analyzer (I use Spectrogram) helps, one can see the beat to a lower frequency that normal hearing.  Just watch the amplitude of the signal - when the beat goes to as close to zero as you desire, you are "there".  I have found that I

Re: [Elecraft] Frequency Accuracy and stability

I count beats.  One beat in 1 second and I'm off 1 Hz.  One beat in two seconds and I'm off 1/2 Hz.  Easiest done if the side tone and received signal are adjusted to be close in amplitude and there's little/no QSB.   Zero beats, and the frequencies would be exactly the same, but the practical

I ordered my K3S with "KTCX03-1-F TXCO 1ppm f/w correction to 0.5ppm".   K3S-F s/n 10163 I use CW mode and CWT mode and tune to each of the WWV frequencies.  By pressing SPOT the radio resolves to the WWV frequency but will show any error either + or - of the WWV frequency.   By tuning up
