I don't have any but several of my neighbors do. I told them my problem
and asked if they would mind if I just ran their fence line and fixed
whatever I found every now and then. All welcomed me. The problem is
almost always an arc to the T-post, a tree trunk, a tall weed that has
grown up under the wire, and the like.

Yep. One of the fences is over a mile long, and even though it is
installed well and I've been its entire length and it is clear of arcs
and bad splices, I can still hear it weakly. Ordinarily, the current
drawn from the charger on a pulse is miniscule ... it's just a voltage
pulse. I suspect that the long fence exhibits enough capacitance that
it actually does draw current from the charger on each pulse, and Pwr =
Voltage X Current. The K3 NB gets rid of all of it.
