[Elecraft] Drift-K1

[Paul Gates, KD3JF]

I have been reading these messages about the drift and or change of frequency when you move the K1. So, I just turned my K1 on for a few minutes and it is just as solid as a rock. I turned it upside down and moved it around but no change in frequency. I figure I should be happy about that!!

Anything that squeezes or otherwise distorts the K1 bottom cover plate (such as when the case is grabbed during repositioning) will cause a small frequency shift (I see well below 100 Hz), due to the change of metal bottom cover plate position near the LC VFO circuitry on the RF PCB.  The frequency returns to original when the pressure is released on the bottom cover.
