I have read the book a few times. It was observed that the mood of the whole base would change depending on what they were doing with the biggest RF dish in the world. Once paying attention, they noticed
it worked better off of the BACK of the dish. I'm
thinking it has something to do with 'harmonics'.
Sympathetic waves produced like hitting the
string on a guitar right above the 12th fret. Same note just an octave higher. Radio frequencies are what made this happen. As with everything else they have figured out a way to miniaturize it. Docs offices have to have something in there producing RF.
