Unfortunately there are so many things that can interfere with AM that there is probably little that you can do that will work except to tune to a different station with less interference.
This is why FM was developed, it is much less sensitive to interference.
There was interference with the radio signal.
The term often used to describe interference of radio waves is "radio frequency interference" (RFI). RFI can disrupt the normal operation of electronic devices that rely on radio frequency signals for communication.
Electrical interference is messing with my radio reception.

Concrete interferes with wireless communication by weakening the signal of the radio frequency. Concrete's ability to weaken or completely stop radio frequencies from travelling through it are what causes the interference.

The interference of radio waves is commonly referred to as "static" or "noise". This can be caused by various factors such as atmospheric conditions, electronic devices, or other radio frequency signals.
Fiber-Optic
Prevent radio interference.
XM radio does not have static interference. It's a digital signal, so you'll either get a crystal-clear sound or none at all.
