While it is true most problems seem to be caused by bad
connections in the fence, the most severe problem I had with
an electric fence was caused by a charger! The charger was
sent back and the replacement charger produced exactly the
same problem. I put RF chokes on it, ferrite beads, you name
it.

My neighbor switched to a different brand and the problem
vanished.

I've generally had varying success with an AM broadcast
radio, but a VHF aircraft radio always lets me walk right up
to the bad area.
