Hello Sterling:

You need to take the ionosphere into account. If memory serves me, AM
radio does not get through, while FM does. TV gets through, too.

Hence the images of Hitler at the opening of the Olympics being picked up
and re-transmitted in "Contact." Or I Love Lucy in an episode of Amazing
Stories.


But, yes, your are right, we are filling space with noise.
