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?
