What steps do the group suggest I take to try to eliminate noise that virtually
obliterates AM radio reception.

It emanates from the AC side of my new AC/DC fridge. When the unit runs on DC
only power, the radio is clean. When I switch on AC, I get a loud high pitched
noise that sounds like the old "heterodyne whistle" of early radio days.

What kind of filter do I need and where do I put it??
