Default Let's do some actual listening and see what happens.

I was hoping not to be the token inventor here but the noise pulse shows
up on my scope (4 channel x 100MHz Tektronix) and if I just had a
reference to the 60 cycle I could set up a few one shots to cut the
beginning to the other end of the noise pulse. Kind of a notch filter
for noise, not adjacent channel. Traditional noise blankers have to see
the beginning of the pulse and guesstimate the end of the pulse so some
noise does get through.



You're just seeing what's in sync with the trigger. Try using a
spectrum analyzer.
