“Skip Distance” a Radio Mystery (Dec, 1929)
This, of course, is the radio waves bouncing off of the ionosphere. I think they’ve known this for quite a while though. Does anyone know when it was figured out?
“Skip Distance” a Radio Mystery
TO MANY uninitiated to the mystery of radio the phenomenon known as ‘”skip distance” is most puzzling. The layman might reasonably assume that the closer one is to a broadcast station the stronger the signals received. That is largely true with ordinary longwave stations but with a shortwave transmitter the situation changes. For instance a short-wave transmitter in New York operating on less power than is ordinarily used by long-wave stations may be picked up in Australia but not be picked up at all by receivers less than 500 miles from the transmitter.
