AM Radio Interference
- Thread starter gratcho

Ron the 1st step he needs to take is improving the signal to noise ratio. It sounds like at best he has a compromise antenna.
He needs to get a dedicated AM & FM marine antenna.
After that he might find the AM signal is strong enough that no further interference mitigation is needed.
If he needs to try and filter the frig I have some suggestions they include but are not limited to, bypass capacitors, ferrite chokes and proper grounding of the frig power swupply.

That's why I asked him about the antenna. Earlier I posted steps to determine how the interference was getting to the radio. Antenna or power leads. He needs to do that testing before trying to fix the problem.
As for the bypass capacitors and ferrite chokes, he would need some pretty detailed instructions on where and how to connect them for them to work and so he doesn't create an electrocution hazard, especially if he's working on the 120 volt side.
For grounding, it should already be grounded but there could be a problem with the ground.
