Frequency Shift

I would like to thank all who responded to my question about frequency shift during filter bandwidth changes on my K2 (see below).

It appears that the shift is no larger then 20 HZ so I guess everything is normal.

Thanks again and happy holidays to all.

I am the owner of 2 K2s, one a K2-100 and the other a qrp model. I built one of the rigs myself but completely aligned both rigs.

My question.
What can I do to prevent slight frequency shifts when changing filter settings?
Both rigs exhibit this problem. The shift is only about 100 hz at the most but I don't think this should happen.

Other then the small shifting problem the rigs work perfectly.

I know there has been solutions posted on this forum in the past but I seem to not have the ability to search for them.

I am using the spectrograph program and following the procedure that accompanied it when downloaded.
