Noise blankers have never worked well, or at all, on most power line
noise which is usually caused by very small arcing in the distribution
line [usually around 12 KV in the US] hardware on the poles. It's
multiple arcs, and the noise pulses from each one overlap each other
producing the rough buzz.
The K3 IF NB worked far better than great for me when I was surrounded
by electric fences and it's puzzling that anyone is having problems
getting it to work. Ignition noise tends to be a thing of the past, but
in the few times I've encountered it. the NB was extremely effective as
well, and easy to adjust.
I don't remember who first came up with it ... I thin Art Collins had
some role ... but it was light years ahead of the old Lamb Noise
Limiters such as in the SX-28.
