K2 dial calibration

[zeke7237]

Trying to use Wayne's procedure for calibrating my dial using WWV on
10 Mhz. So I tuned it in using Spectrogram with 500/600 hz markers to
match the tones. Tweaked C22 till VXO and BFO matched up. Ran cal PLL
and cal FIL. Now I hear the signal fine, USB/LSB/CW, tuned in fine,
but the display is off over 5 Khz! I'm not sure what I'm missing, but
evidently it's something :)  Any suggestions out there?

John,

That sounds like inverted sidebands to me.  Try presetting the CAL FIL BFO
values to those indicated in the manual to get things in the ballpark and
then go through the procedure again.  The procedure does work FB, I use it 2
or 3 times a week on K2s that are in here for repair/alignment/calibration.

If you want additional information, look at the K2 dial calibration article
on my website http://w3fpr.qrpradio.com
