If you are actually interested in working with people to learn how any of these EM Signals etc. are being generated and detected then I recommend that you try to talk with people who are detecting Ear Tones.

Those people appear to be everywhere. And this is an area of science where things could be much better organized and explained. I don’t have time myself to do any research on these signals. Efforts have to remain focused on the computer programming parts of the work etc.
