Brian, That is entirely normal. Which one of the 3 methods mentioned are you using to calibrate the 4 MHz reference? 1) Measure the TP3 frequency with an accurate external counter - adjust C22 until the K2 display matches the external counter. 2) Listen to the 4 MHz signal with another receiver - tune C22 until right on 4 MHz. 3) Just set the C22 trimmer slot to the midpoint.
Actually a better method (greater accuracy) exists - wait until you have completed the K2 and you can receive 10 MHz ((or 15 MHz) WWV, then use the N6KR method. You can find the "How-To" on my website www.w3fpr.com article on K2 Dial Calibration. 73, Don W3FPR Brian Denley wrote: > While doing the 4 MHz Oscillator calibration, CAL FCTR shows 12100.10 which > seem nominal.
