well,
I have run into much the same issues here.

I have taken to grounding everything I can, putting ferrite beads on =
everything and even applying a couple of line filters. All of this helps =
to cut down noise that might be getting into other equipment. However, =
nothing beats having the antenna as far away from everything as you can =
get.

I still can't transmit on 40 meters when the front TV is on. It causes = the
switching supply inside the set to shutdown. about the only thing I =
haven't done is move the antenna further away (which is not possible = given
the current layout of the lot here). any other ideas?
