You will get no help from the fcc and very little from the manufacturer. =
If I had the same problem and was on good terms with the neighbor, I =
would offer to replace the device with a ul rated wall mounted =
transformer (that is really a transformer) if the output is ac, or a ul =
rated dc power supply if it is dc. Another option is to buy him a =
similar, but higher quality lighting system and trade with him. Pay an =
electrician to install it unless it will just plug in. The cost is =
probably less than $100 and it will certainly make your life more =
livable. I wish I could find the source of noise here and solve it for =
just $100. Mine is more prevelent at night and maybe a lighting problem =
also. =20
You might post another message with a lot more details of how you found =
(located or isolated) the problem and what kind of lighting system, =
including any brand, p/n, etc., that might help some of the rest of us =
find a similar problem.

Some really strong broad band noises have been polluting the low =
bands here. I finally tracked it down to my neighbor, who has a couple =
of wall transformers powering various lights in his house. It turns out =
the transformers are generating noise like crazy. I suspect there are =
SCR devices inside, with no actual transformar at all. They are rated =
at an output of 12 volts at 60 Watts, which is a lot more current than a =
typically sized wall transformer usually puts out. Does anyone have any =
ideas or experience on how to cure this type of noise problem (short of =
building an actual fused transformer that handles the load)? Also, will =
the FCC do anything about this kind of thing if the neighbor does not =
cooperate? Will the manufacture be required to do anything by the FCC? =
