That's precisely the kind of noise a "noise blanker" is designed to take
out. I've got several around me [including mine], and the weeds grow up
in the spring along the fence lines and start the arcing. My neighbors
allowed me to locate the offending flora and cut them down without
asking every time. Then I got a K3, and haven't prowled the fence lines
since. :-)
The AGC parameters can also be of great value. From memory [thus don't
quote me], AGC PLS NOR will put a small delay into the AGC action so the
noise pulses, if short enough and mine are, won't activate the AGC.
Between that and the NB, I hear neither fences nor NB artifacts.
Sometimes I think the K3 AGC is maybe a tiny bit "overparameterized,"
I'm happy with what I finally ended up with and don't touch it anymore.
:-) Too many choices for a ham of 61 years.

Down the road is an electric fence that from time to time causes some
clicks on 75 meters. In the past this was not good news - you either
tolerated it or used the NB on whatever rig I was using. The NB then
caused the "broad front effect" resulting in lousy RX audio etc.
Yesterday, I tried the NB on the K3 - what a wonderful surprise! It
worked with ruining anything. Perfect!!! No clicks and unspoiled arm
chair copy on 75 meters. It doesn't get better than that.
