Hi folks - I have an OMNI V.9 stacked with Inrads. I use two 400hz Inrads, and a 250. Every once in awhile on 40 m (usually when QRM is up)it sounds as if the mechanical clicks of my ProfiII keyer are comming out of the speaker - don't know any better way to describe it. Anybody even have a clue as to what I am trying to describe? Thanks Tim Logan KB7OEX
