Good Day to all, I have had prior problems with my neighbors electric fence used to contain his horses. I don't have much experience with the NB in the K2. i am using the K3 which does a wonderful job. I guess the first thing I would do is make sure the interference you are hearing is in fact the electric fence. Do this by isolating all of you equipment from your shack power source. If the problem persists, then I would turn off all power to your house and check if the problem is still there. If so, it is time to go mobile or portable with the K2 and an AM receiver. I think though I shoud first confirm that the fence is your neighbors or is it yours? If is your neighbors, I would suggest contacting them and nicely explaining the situation. When I did this, my neighbor was very cooperative. i explaind it as "MY Problem" and asked him for permission to access his property to explore for the problem. In my case the fence was located across the street and kiddie corner , approx. 500' away from my house. The fence covers appox. 5 acres. I found that the problem was somewhat "weather" dependent. An example was just after a good rain it would really take off. It seemd as possibly some large field grass or weeds would touch the fence and act as an antenna. Upon investigation, I found that the fence was badly neglected and had several open portions and very poor grounding. I asked my friendly neighbor to disconnect power from the fencing unit and guess what, the interference vanished. I then asked him if I could make some repairs to the fence and excplained my intentions, which I might add quickly included purchasing at my cost, a new electrice fence module. I proceeded the jump all connections that were hanging open in the fence circuit as well as remove the existing the grounding system which i might add consisted of a piece of 24G wire that was spliced several times terminating to nothing more that a large screwdriver that was shoved into the ground. This was all replaced and neetened up, and terminated with a nice new and shiny 8' ground rod. I plugged in the new power unit to see if all my efforts were helpful. To my amazement the problem was completely gone. Oh I forgot to mention, also pay close attemtion to all splices in the fence as well as the gate hooks that are sometimes used. The can arch over and act as quite the spark gap transmitter. I hope this gives you a place to start. Please reply with any further questions.
