This has nothing to do with the NSA, and the NSA has no interest in RF noise. The noise isn't some encrypted electronic communication. It's electromagnetic noise as a byproduct of poorly designed electronic products. It's like if in a chemistry lecture if all the students started humming, it would become difficult to hear the lecture. So there is no connection to the NSA.
