[Elecraft] Weird K2 tuning thing (hand capacitance)

[K1FFX]

I had a problem with my K2 in the weeks after I built it that sounds similar
to what
you describe, namely a significant change in frequency when pressing down on
the top of the case.

I posted here about it and Don (and others) suggested that I have a look at
L33.

Visually, it looked OK, but I was reluctant to remove the part and try to
clear
more of the soldered joints underneath the rubber insulator ... so I didn't
go
there.

What I did do was (a) remove the tilt stand, which relieved a pretty severe
twisting pressure on the case and (b) put some additional spacers, in the
form
of left-over washers, on each of the stand-offs on the bottom-side of the K2
to move the bottom panel further away from L33.

While this was not proof that L33 was the problem, it did make the problem
go
away.

Cheers -

Bruce
