Last week I was getting some really bad noise on any receiver in the house. It was clearly man made and was really harsh. After it didn't go away for a couple days, I went out and decided to DF the source. I found the problem around the corner, no more than 50 yards line of sight from my house...a burnt out street light that was giving off severe RFI. I went home, got on Southern California Edison's web site where they have a form for street lights out. I filled out the form and also indicated the RFI problem and that I had DF'd the source to the light. To my surprise, they were out within two days and fixed the problem! Who woulda thought....
