I have a horse farm behind me that has electric fences all over their smaller pens and larger pastures. When it is installed correctly and the sender is working correctly they are quiet. Unfortunately, his are not. In some places he has the hot wire mounted below the lowest fence board to keep the dogs from moving in certain areas where some of the wire is touching the ground. The whole place needs completely redone. Luckily, setting the NB on the radio to its lowest setting keeps the pops away and the intermod is tolerable except in contests. I can usually just walk the fence and hear it arcing, or I can tell which section is arcing by putting my one good ear next to the wire and listening to it ring. I used to put ferrite beads and capacitors in the older controllers to roll off the sharp transition of off and on; I don't have to do that any longer. The bottom line is that if installed correctly and if using any recent controllers, you won't be bothered.
Jim - KR9U ___________________________ Funny thing about electric fences... I lease out 9 acres of my property in KH6 to a farmer who has an electric fence around that part of the property. As far as I can tell it is totally silent. I parked my truck next to the fence, tuned to 1710 kHz and other than background noise, it was totally quiet...no pops etc. No antennas up yet, but this certainly looks promising. Any thoughts?
