Hey guys,A quick update. While experimenting with the radio thing I noticed that on a particular AM band (actually several) I would get noise. I waved it around the room looking for the worst spots. Of course all were bad enough to render the radio unusable. In one area of the building where the supply comes in it was particularly bad BUT as I moved toward the ceiling I would start to receive a phantom radio station. Very odd.
Another more disturbing observation. There is an area on that whole wall (north wall) where the power comes in. All along the floor it is extremely bad as well. The unsettling thing is that on both of those walls the paint is peeling in only those areas! I had discussed this with the owner before we moved in and she wasn't sure what caused it. Having spent several years in autobody repair I have a general idea of various causes of paint failure. One thing I have heard is that this can be caused be high levels of powerline radiation. Anyone have any thoughts on that?
Oh ya, when compared to the transformer down the street (and all the others I've seen in this city), ours must be 100 years old :) It is literally rusty (but I can see clean connections through optical magnification), and there are heatsink style fins around the whole thing which I've never seen. I remember my first experience with a transformer that blew about 100 feet from where I was working in the mid-80s and even that was not of that style.
