I would definitely unplug all of my sensitive electronic equipment while
running it. :) I myself even with my small coil, (15/30 NST) am going to
pound some sort of copper pipe in the ground, and connect to it with
automotive jumper cables...





I was wondering what to do with the RF ground as well Gary.  I'm a bit
