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.
