I have a pulse noise that I thought was a fence charger, but it is to the north and the only electric fence that I have found is south east. In another internet discussion someone mentioned that he had traced a similar interference to a blinking caution light. Sure enough I have a blinking caution light 1.5 miles to the north. Fortunately for me the interference is very light and can only be heard on a nearly dead band. Fence chargers are not the only source of a pulse with about one second interval.
