When listening to FM (or AM) on my radio, I get interference whenever my battery charger comes on. Is there a simple shielding device available to block the interference? Phil

what kind if charger is it? There are different causes of noise depending on the charger, conducted and radiated. If ferroresonant, it is conducted noise rather than radiated and the solution is more difficult.

Ferrite cores around the wires can help suppress some of the conducted radio noise.

Radio Shack has an item called an RF Block that should take care of that. It is under $10.
