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.
