K1 slightly frequency shift

[Elecraft mailing list]

 Hello

since a week I am also very happy owner of a K1 with the 4 band module, atu and nb board.

The rx is amazing, but I notice a slight shift of the vfo if I am put my hand on the top cover of the K1.
I notice this shift, about 100 hz, also after a longer warm up periode. Even when I put one or two fingers above the vfo dial.
Any hints to reduce this little frequency shift?

Hi Harry,

I have purchased an X-Lock frequency stabiliser kit from Cumbria Designs,
cumbriadesigns.co.uk. I have not built and installed it yet so can't
comment on it but positive reviews and good article on installing it in the
K1.
Cheers,
Glen VK1FB

Hello Glen,

got the info about the X-Lock also from G4AON.

But I am not asking about a drift in general, I noticed this small shift only if I put my hands on the top cover.

Harry,

Make certain L1 is mounted properly.  Something is apparently moving in
relationship to the L1 winding and causing the coupling to change.
