[Elecraft] K2 - best frequency accuracy?

[David C Dawson]

My question is a bit complex:

first, by using rig in CW mode and tuning to 10 MHz, I turned on the spot function and tuned the VFO to zero beat with the station carrier. I followed the VFO setting procedure on page 101 of the K2 Manual, and seemed to get it spot-on (maybe +/- 5 Hz?)

Then I compared the frequency accuracy with different filters and found that the zero-beat frequency seems to vary with the filter.
(not by a whole lot, maybe within +0  -  +30 Hz above the second-widest CW filter.

I'd like the VFO frequency to be accurate as possible, and I realize that the BFO needs to be just as accurate.

I'd like the filters to be consistant.

My question is:
How can I set the VFO as accurately as possible, how accurate is that, same with the BFO and filters?


Thanks
