The gentleman who was having problems has found the cause. He swapped
the KNB3 from the sub to the mainRX. In other words, the KNB3 in his
mainRX was not functioning properly.
Yes, the NB does not do too much for power line noise - it works well on
impulse type noise like automobile ignition noise and most types of
electric fence noise.
In other words, use NR for more constant type noises like powerline buzz.

I'm really surprised by all these negative comments about K3 NB. Mine
has been very effective on electric fences (I have one!) and power
line noise.
