[Elecraft] K3 static electricity

[Alan Sewell N5NA]

I had this problem occur with my Omni VI back in the 90's.  When I would 
walk in the room and touch the VFO the rig would shut down.  A friend 
across town had the same problem with his Omni VI.  It took us a while 
to figure out it was static electricity.

Ten-Tec's fix was to send out a short piece of braid with a solder lug 
on each end.  One end went around the encoder shaft, the other end was 
attached to the rig chasis.  That solved the problem.

Someone said "Static electricity is YOUR problem, not the K3's."  I have 
to disagree.  The K3 shouldn't be susceptible to static electricity.
