hi Gale, very interesting, we have a plasma Tv as well and I've
never noticed in an increase in the noise when it is on. It's
separated from my HF rig by two rooms maybe 25 feet. I live in
an apartment building and my antenna traverses over two buildings
so I guess I am lucky not to have a continuous s 9 noise level.
Sorry I have no ideas but am interested in knowing what Plasma Tv
noise sounds like. Best 73's, Jim WA6EKS
