WWII radio plays WWII broadcasts!

Then there's "The Waveries"...a SF story I read as a little kid. Seems folks began picking up the letter "S" repeated over & over...then scraps of voice...bits of music...30s radio shows. Someone figured out that the initial signals were Marconi's first tests, followed by Fessenden's tests, early broadcasts...all in the order they were originally transmitted. By the time signals from close to the present day were beginning to show up, it was too late to stop THE ALIEN INVASION!!!!
