[Elecraft] re K3 shut down due to static

[Fern Rivard]

    A while back, I had a problem where sometimes my K3 would shut down and immediately power back on when I would attempt to touch the main vfo knob. I had installed the encoder properly by inserting a star type of washer on both sides of the front panel to provide a good ground. However, I suspected that it was likely a poor  ground of the VFO A encoder but I didn't really want to remove the front panel from the rig (to do the ground on the back side of the front panel) as I had quite a time to install the front panel on there to start with. So, I removed the PTO A knob, nut and washers and carefully removed just enough paint around the hole where the encoder was mounted so that the star type of washer would bite into bare metal to ascertain that I had a good ground but being very careful as to not scratch the front panel so it would be good idea to use a bit of masking tape just in case one slips.
    Now, I haven't a problem since so I suspect that this is what the problem was with a poor or none existent ground to the A PTO encoder. Jus thought that I'd pass this one just in case somebody else experiences the same problem. Now what I would do if putting a new K3 together is to remove enough paint on the back side of the front panel around the holes of both the A PTO and B PTO encoders (I never did have the problem when touch the B encoder).
