Steve,
That is exactly how I tune WWV before reading the VFO (TP1) and BFO
(TP2) frequencies. Adjust Control Board C22 until the 3 lower order
digits match (since you are listening to a station known to be on a
xx000.000 boundary the subtraction process is a snap.

I was wondering if anyone had tried doing the reference oscillator frequency
calibration for a K2 without the rather troublesome step of accurate
zero-beating by feeding the 500/600 Hz audio tones from WWV/WWVH to a computer
sound card or smart phone spectrum analyzer, or similar program? It's

You are correct. I do have the freq counter probe.
It is the RF probe that I need, if you have it. Otherwise, I can get
one from Elecraft.
BTW, this rig works great just as you built it! I didn't have the fun
of putting it together but I do enjoy going through the manual and

Drew,
Yes, it is K2FCTR and is priced at $10. Om the Elecraft website, click
order and scroll down to 'Spare Parts and Mod Kits' (or something like
that) - it will lead you to it. Or, you can make a phone call to order it.

Is the freq counter probe assembly available from Elecraft? I bought a
constructed K2 that doesn't have one included. I'm hoping I won't have
to lookup and order the crimp pins, housing and rg174 coax from
Mouser, etc. in order to make one up.

Adjusting C22 has no immediate effect. You must do the entire procedure
of CAL PLL and CAL FIL before any change will be observed.
See the K2 Dial Calibration article on my website
http://w3fpr.qrpradio.com for details and procedures.

All,
Thanks for the input. By following the instructions from the inputs I
received, I was able to calibrate K2. I'm all set. Thanks for the help.

Speaking of zero beating, why not get an AM receiver tuned to WWV and
zero beat the tone from the AM receiver to the SSB receiver? That way
you can get within fractions of 1 Hz and it's a lot easier than watching
a computer screen.

Michael and all,
Yes, because the K2 has independent BFO adjustments for USB and LSB you must
know that both BFOs have been properly set before you can do 'tone matching'
to determine the correct dial setting. It IS a good method to verify that
one has achieved correct calibration, but if the dia
I've found that using the frequency calibration method in which you switch
between LSB/USB when monitoring the tone (tuning for the point at which
there is the least difference in the WWV tone between LSB and USB) on WWV at
15 or 20 MHz works very well on my Kenwood TS-930S. Given the fact that t
