[RFI] Rfi from a neighbor.

[Lee K7TJR]

     Having sold electric fences for a living, I can tell you that the recorded ticking on the ARRL site is not from an underground dog fence. The underground dog fence wires use a continuous RF transmitter loop and a receiver on a dog collar. It only shocks the dog when he goes across the underground wire. That ticking in the ARRL mp3 is from an above ground electric fence. Two important things. There will generally be no noise from an electric  fence unless there is an arc somewhere. Most often due to bad connections somewhere, or the high voltage wire is touching something that is grounded. Most people using these things have very little understanding of electricity and how it flows. I have seen installations where people just staple the wire to a wooden fence and then wonder why it did not work when it rained. These things operate at Kilovolts and up. Second important thing is that some cities or municipalities actually have ordinances against electric fences being used within their boundaries. It might be worth checking with local authorities. This could be used as a last resort. Some people here in the Pacific NW actually have electric fences around their backyard fish ponds to keep the Racoons from eating their often expensive pond fish. No dogs involved so be sure and check things out before any direct accusations.
