I have a good ham friend who has been creating a lot of RFI with a
nearby neighbor. The RFI is mainly coming through the neighbor's PC
speakers and TV speaker. No one else in the neighborhood is affected.
It doesn't matter what band or how much power he runs, 2-40 meters,
5-100 watts, he creates RFI. His own home equipment, including a TV
and PC in the shack are not affected. The only odd thing we can think
of, is his neighbor's roof is all tin. We don't know if there is a
ground on it not, but the question is: Could the tin roof be a
contributor to his problem? Would a good ground of the tin roof help?

Thanks...


Odd, but try having the neighbor operate his computer inside the ham's house
while transmitting. Does the neighbor's computer still act improperly? If
so, that eliminates the roof question.

Also, try a couple of the ham's electronic gadgets in the neighbor's house.
Do the gadgets still work OK? If so, another reason to absolve the roof.
