Of course, to get the full benifit of this, you have to be wearing the 
official Art Bell tin foil hat for $19.95.



In the mid-90's there was a Ken Burns documentary on PBS called "Empire of 
the Air" about  3 giants of the early days of radio: Edwin Armstrong, Lee 
DeForrest, and David Sarnoff.  It prompted me to read the book of the same 
title which I got on tape from NLS.

Armstrong, who is credited with inventing FM, did an experiment in the '30's 
or '40's of transmitting a short-wave signal and listening to it several 
times as it circled the earth  every so many seconds.  Maybe obvious today, 
but a big deal at the time.

Not quite the same as signals returning from the great beyond  after 
decades, but still interesting.  If you are interested in the  early 
pioneers of radio, I'd recommend the book.
