[Elecraft] K3 - noise reduction query

[Eduardo González]

Probably K3 NB is not effective filtering your particular noise. Impulsive
noise is very hard of characterize because are infinite patterns possible.
I have filtered majority of arching noise but eventually not was possible.
You are tested NB analog and NB digital and combined both?
I remember a 11m radio (3-5825A) with a NB more effective than TS-440S,
with only a particular noise.
Recently I discovered a static noise effectively filtered by IC-736 but a
IC-781 wasn't capable
We must accepts not cheap equipment wasn't capable filter a type of noise
is frustrating.
