Interesting. That is a distinct possibilty. I may have inadvertantly tied the
2 ground systems together. I do have a nice RF ground system though. It
consists of (5) 10' x 5/8" copper clad rods driven into the ground 9' apart.
The top of each rod has a 2" wide solid copper strap soldered to it that
interconnects each rod. Another solid copper strap connects the whole buried
assembly to the base of my coil. I actually didn't get any complaints before
the other day though. I have to get back over to the neighbors and talk to
him about it.
I will test the house for RF though. I could also use another in-line filter
or 2. I also need to sheild the house wiring in the garage. I know it is
acting as an antenna. It even lights the incandecent bulbs in the garage when
running. I hope to accomplish all of this, including the Faraday shield, this
weekend.
Inadvertantly Transmitting in Ohio,
