To rf_engineer and all, here is a link to Fogal's work.
There used to be additional information on some of the very interesting results from work he and people with him were able to obtain but I need to Re-Find that information.

www.eskimo.com/~ghawk/fo ··· _device/One of the descriptions of tests they did was of putting Video within a 5vdc line but using a signal that would not be detectable with your normal O'scope (1mv) and another where they showed extracting large amounts of additional data that was already available within a regular recorded video (VCR) tape.
This I found very interesting from the point of view of medical work.
Just some thoughts out loud but I would hope Fogal does get some Credit down the road for his work.
