Hello All, thought I'd post latest. I started from scratch;i.e.. one cabinet,one amphenol(eight stations) and it wasn't until the last extention module(there are two) that the noise reappeared. Next step; add one station at a time and see what happens. Sometimes I need knowledge reaffirmed; if that makes any sense. Although I still am curious if anyone else has had ksu be the culprit in regard to phantom noise. Thanks again for input!!!!!
