A properly maintained electric fence will have ZERO RFI. I have one that is inches away from the KA1GJU Super Station #2 feed point. (On the same wooden post!) to keep the cattle contained. If I look very carefully at the waterfall, I can ONLY see the horse farm and two dairy farms that are 1/4 to 1/2 mile away in various directions thanks to my nearly weekly walks along the fence to remove tree branches, vines, tall weeds,l leaky insulators (cracked insulators will make snapping sounds) etc. This HAS to be done with every thunderstorm since some of the fence is under the canopy of trees in some locations.
If you talk to the owner, would he/she let you walk the fence and remove such growth? Worth a try, since it's a win/win for both of you.
On a non-SDR rig, the NB will make strong signals sound distorted, until you figure it our that the NB was on. My Icoms are used by remote users and sometimes I find the last user had used some VERY bizzare settings, as if they had no clue as to how to use an HF rig. There should be no reason to turn NB, NR, and AN on all at the same time!
