If the transmitted signal did indeed affect something, then a cw note would "blossom" if you held the key down, because it would heat up the affected layer.  It would be repeatable and predictable, or it would not be scientific.  

This non-linear ionization affect reminds me of the cold fusion experiments in Utah.
