I have forwarded these suggestions to my friend ,who lives in Florida,
I'm in Ohio. He isn't a newsgroup user, so I presented the question
for him to these 2 groups. Thanks for the very good ideas. I've had
RFI before, but never with someone who has had a metal roof and
frankly don't have any idea if it's contributing to his problem or
not. If we figure it out, I'll post it. Thanks again.
