[RFI] Finding house noise sources

[Hare, Ed W1RFI]

In theory, there should not be any hidden junction boxes behind drywall, but as I have seen on Holmes on Homes, that's not always the case. :-)

I think I'd be inclinded to use the noise itself as my cable tracer. I'd use a VFH AM receiver with some sort of S meter and a very small loop probe at the end of a piece of coax. Many HTs receive AM in the aeronautical bands.  You may also need an attenuator to reduce the noise to a level that just moves the S meter. You can then trace the wiring behind the walls because the noise would be stronger near the wiring.

The S meter may also tell you the location of the noise source. Although it would be noisy along the entire wire, it would generally be an S unit or two higher near the source.

Gary,

I suggest you investigate a tone generator & cable tracer kit. I got several hits list them with a web search.
