While respecting your expertise, with dozens of sources polluting our environment, it's easy for those multiple sources to obscure each individual source, and lead us to believe that none of them is contributing. AND we hear our neighbors' sources.

I strongly urge everyone to replace ALL switch-mode supplies with linear supplies and repeat any tests to prove that your "stuff" is not part of the problem. I run lots of "stuff" on small sealed lead-acid batteries that are float-charged from linear supplies -- everything from cable modems, and routers to video monitors and stuff in the home entertainment system -- and that helps. Yes, I stil hear trash from my neighbors, but that's several dB down. Every little bit helps us hear the weak DX. Yesterday, I worked an AF DXpedition on 160M, 7,500 miles away.
