[RFI] New RFI Source

[AA5CT]

 Another possibility - aquarium heater? One of those jobbies that clamps over the edge of the 
aquarium in a glass tube maybe an inch diameter and 4 or so inches long.

  I'm in the middle of a city, so there are no electric fences or horses nearby. 
  I was able to hear it with a portable receiver just now. As I was standing near a neighbor's house which seemed a likely source, it just stopped. A few minutes after I got home, it started up again. Assuming it persists, I should be able to track it down and post the results.

 How close to somebody with a large fenced horse yard do you live? 
  Sounds like an electric fence charger cycling.

   I'm hearing a new local RFI source. It produces a 1 second burst of 
  broadband noise at regular intervals of 3.5 seconds. I'm hearing it on 
  80 through 15 meters. In AM mode, it sounds like it's modulated at 120 
  Hz. It's very broad-band, so not likely a switching supply.
  
  Any ideas on what kind of device might be producing this?
