[PPRAANet] RF Noise

[Mick Sparling]

Hi,
It seems like "door bell transformers" are notorious noise generators.
Does anyone know how/why they seem to fail so often?

Jerry Van Derf (sorry if I misspelled your name Jerry) suggested I contact the Colorado Springs Utilities.  With their help, I was able to locate the source of the noise to a neighbors house.  Jim Rader, Jim Bishop and Virgil Yost helped me work with the neighbor to isolate the problem.  Apparently the problem was a door bell transformer which the neighbor has since replaced.  He said he had been hearing a buzz in his house since about the time the RF noise started.  The buss was from the transformer.
