[Elecraft] Frequency Shift

[David Robertson]

Hi 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.

I must be doing something wrong. It must not be the radios as both exhibit the frequency shift when changing filter bandwidths.
Any help or advise would be appreciated.
