P3 and CW signal not aligned perfectly

N0SA
I have a K3 with the P3 panadapter.
When I properly tune a CW signal in and us the SPOT and CW indicator I notice that it is not centered in the P3 display. If I center it then it is off by about 30 Hz.
It shows the same offset if I change filters and go to REV CW.
My SHIFT is centered.
Is this normal or do I need to check and adjust something?
Thanks

On the P3 there is a menu function to calibrate the frequency.  Do this
and you can set it perfectly.

Have you properly performed the P3 Frequency Calibration per the manual
procedure?

Perhaps coincidentally, yesterday my P3 was also off by 30 Hz based on the carrier frequency of BCB stations.  It had been dead-on since I calibrated it over a year ago.  Haven't had time to explore further, but will recalibrate if this persists.

That was it, I just needed to do the calibration. I have had the P3 for quite awhile now and just don't remember ever calibrating it or it being off in the first place.
Thanks again for the help.
