There is another way to calibrate (though I have not tried it yet): Transmit a carrier and measure the frequency on an accurate freq. counter. My counter is good to 26-GHz with resolution to one Hz. With it I found my K3 is off -6Hz on 20m and -16Hz on 6m. The counter is referenced to a Rubidium standard.
Adjust the TCXO3 to zero the error at the highest freq. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-800*w, 432-100w, 1296-testing*, 3400-winter?
