[Elecraft] Elecraft K3s, etc. bonding

[N4ZR]

I think the answer lies in the ground bus.  I used a 3/4" copper water 
pipe along the back edge of my desk, with a short pigtail of #2 wire to 
the K3.  I used a yellow-jacketed Home Depot ring terminal on both ends 
of the #2, and metal-tapping screws to connect to the bus.
