I've heard that some microwaves use switching power supplies instead of a
*heavy*, conventional transformer.
If your appliance uses the switching supply, chances are that it's "on" all

That could be the source of your noise. You might try a common mode choke
on the power cord...see if that makes a difference. Study the choke info on
