Frequency Calibration

My K-3's frequency appears to be off. I didn't notice it until I worked
a couple of locals on our net freq. of 28.355 and had to use the RIt to
tune them to my freq.

Zero-beating WWV at 10khz actually reads 9.999.6.

The rig had been on most the day and I did try Method 2 (zero beating)
on page 50 of the manual but didn't seem to make much of a difference.

Is there a way to calibrate K-3 without a signal generator.

Re: Frequency Calibration

WWV is a great signal generator.

A 400 Hz difference is way off!

Method-2 works, no problem. I set mine months ago and it is still
within a few Hz of WWV. Make sure you are doing the zero beating with
the RIT off.

FWIW, my ref osc is at 49.379.918. (Not sure how much that figure
might vary from unit to unit...)
