[RFI] Electric Dog Fences - What to Buy?

[Mel Crichton]

DogWatch is good...........

When we installed a DogWatch electric fence some years ago they provided the addresses of a few local customers. I drove by with the AM radio and could not detect RFI. So we installed it. No noise, even on 160 meters where one beverage passes over the loop

When lightning took out the system a couple years ago they replaced the transmitter and wall wart supply (under warsanty), and suddenly there was RFI. I traced it to the wall wart and took it back to their store to show them (with my portable radio). They were surprised at the RF noise coming from the current model and gave me an "updated" unit the factory had just sent. It was quieter but still had some noise. Noise was worse at the beverage. So I replace it with a wall wart fomr my junk box, problem solved.
