COMMUNICATIONS are being revolutionized faster than you think. The humming wires beside the highways already are rivaled by new systems, capable of transmitting more spoken or written words and more still or moving pictures from coast to coast. The difference between these new systems and those of the past is as great as that between oxcarts and stratoliners.

Static from the Stars (Jan, 1948)

Static from the Stars

Because a radio ham heard strange sky noises, we may get better FM and television—and learn more about our universe.

By Herbert Yahraes

Drawings by Ray Pioch WHEN young Grote Reber was a high school sophomore, he operated 9GFZ in Wheaton, Ill., and tacked so many recognition—QSL—cards to his bedroom walls that the plaster cracked and his parents cracked down. When not communicating with El Paso, Arequipa, Capetown, Prague, and other points, he designed equipment to communicate with them even better. Nobody who knew him then will be surprised to learn that he is still in radio—listening not to the chatter of hams, but to mysterious and bothersome radio waves that come from the heart of the Milky Way.

“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.

THIS new hookup board will gladden the heart of many a newcomer into radio because of the ease with which it allows the novice to hook up his receiver.

Radio Cleared of Slander (Mar, 1930)

No one these days would ever believe anything this silly, would they?

Radio Cleared of Slander

THE rush of radio waves through the ether has not made Paris hotter or colder, dryer or rainier than in the years before the invention of wireless, Joseph Sanson, French engineer and meteorologist, has concluded as a result of a study of weather records for the past two centuries. The same sort of irregularities were present in past years as have been evident in the decade since the wide use of wireless.
