Battery powered base station...Grounding?

[Maverick]

I've got my base running off of 2 car batteries. Both batteries are daisy chained together, then positive to the amp and radio, and negative to the amp and radio. I've got a wire going from my linear to ground. My antenna is a 20" pole attached to the side of the house wired to a 8 foot grounding rod driven almost all the way in.

Still, when I key up with the amp on, if my lips brush up against the mic is shocks me. So, I'm thinking grounding issue, but how can I better ground this setup? any ideas?

Thanks.

Still have some rf in the shack there, hot lips. Ground more, or just a 1/4 wave piece of insulated wire, with one end hooked to the amp or radio case. Tape off the other end, as it may be hot with rf. This will be a counterpoise, or rf outlet, that should help that. If not, maybe you mic is snagging some rf. If this works, run the wire arount somewhere under the carpet or whatever out of the way. -drdx

Thanks Dr.DX, I'll try that. I think it just might be a mic issue. Before I grounded everything every time I keyed my computers would freeze, even barefoot. Now they stay on with about 300Watts. I'll try the 9' wire first though.
