[Elecraft] 4 Mhz Oscillator calibration

[Andreas Hofmann]

Hi,

I used the method mentioned by GU3MBS late November. The method works
very good. However, I am not sure in which direction to move in order to
get the optimal calibration. Here are the 2 WWV QRGs that I tried:

K2 display 			delta
10,000.07			+ 70 Hz
19,999.80			- 200 Hz

Even worse, on the 2 points the deltas are not in the same direction.
Has anyone seen this before? I have seem messages in this list before
with ops claiming +-20Hz. Is this on one frequency only or across the
bands?

K2 2555, A2B mods applied.

Any ideas are appreciated.
