Yeah, I hear what you are saying. It might be possible that it has something to do with human consciousness messing with the radio, it is notable that the human brain is a giant EMF device basically, so maybe it can affect electric devices external of the body via electro magnetics. You could be on to a whole new scientific study of how the mind can affect devices via the consciousness. Interesting stuff I need to smoke a blunt before having a thought experiment on.

Intelligent paranormal activity and demonic activity both which I can assure you from my personal experience are very real. Normally can communicate via EVP, and the best EVP's are when the researchers hear it and it shows up on the audio and requires no audio manipulation to understand the words. These are Class A evp's and those are the best evidence for the existence of ghosts being intelligent and dead human beings and or demonic entities because of the nature of the words being recorded.
