Grounding of equipment on the desk has nothing to do with TVI or RFI, unless you have terrible antenna common mode or other cable issues bringing RF into the shack, or cable or connector issues in the shack. If earth was important, satellites and airplanes would have huge radio problems. I think the myth that filters and equipment needs to be earthed comes from the false idea that filters divert unwanted signals to earth. Earthing is for low frequency and AC safety, unless you run a longwire from the desk tuner. 73 Tom _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
