I hope this works and someone can recognize the kind of interference i get. With my son i did kind of a frequency dependency test with his world receiver, working on batteries. On every frequency the interference appears, 11m, 2m, aircraft band, commercially used bands etc.... So i suppose it must be something like solar panels, LED lights, aquarium pump.......

Wow, can that go so far? With the test with my son we were in the back of the garden and we still got this. Suppose, next thing to do is walking around the neighbourhood to locate the source.

Is this a home base set up or in the car?
As from personal experience, I get that noise when I'm running the engine on my diesel van.

It's a home base setup, At-5555 with a homemade gainmaster 5/8. But i have the same with a president lincoln I and an Antron A99.

Sounds very much like PLT noise to me. Check above 28mhz. If the interference is significantly reduced or eliminated above there, it's almost certainly PLT.
