Well,

All my radio have the same exact hum that is a function of my house wiring and which subides quite a bit when the chandelier in my lobby turns on.
Inluding a small pocket transistor one I have.

This is not a prblem with the radios but with wiring.

Same is the case with my dad's Westinghouse radio I gave him.
I checked, it is present in my car's radio when parked near his garage.

Only on BC band.

I want to make sure this is the radio and not you Mains.
