K2 - reference oscillator will not go to 4000.000 kHz.

zan0416
Pardon me if this is an old topic, but I could not find anything relevant
to this with an archive search.

I have been enjoying my K2 for about a year but have always known the freq
calibration was off by about 1-2 KHz and have just lived with it by
compensating accordingly.  Now that I have a XG3 I want to get the K2 tuned
up as best as possible, which means I'm revisiting the freq calibration
problem again.

When adjusting C22 for 4000.000 KHz I find it will will never actually
reach 4000.000 and seems to bottom out slightly on the high side, maybe 1
KHz or so high.  Any ideas on where to look or how I may address this
problem?

Thanks!
Dan, NØDA

Dan,

Don't worry about getting the 4 MHz reference exactly to 4 MHz - it is
"not necessarily so".
Use the N6KR method to set C22 accurately..  Go to my website
www.w3fpr.com and look at the K2 Dial Calibration article to describe
the complete sequence.

Just as a follow-up, I performed the K2 Dial Calibration as directed on
Don's website and had fantastic success.  Thank you!
