[Elecraft] K1 VFO Drift

[Jonathan Broscious]

My K1 was working great for a while, but now it seems to have developed
a problem. The frequency drifts and the numbers on the screen drift as
well. The faster I twist the VFO knob, the faster it drifts when I am
done twisting. Sometimes, if I tap it rather hard on the top, the
frequency jumps back to where it should be. I tried restripping the
leads of L1, and and touching a hot soldering iron to some of the
joints, and it still did it. However, sometimes it acts fine. Generally,
when I move the rig somewhere, like outside, it starts acting up again.
Any Ideas?
