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

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.
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.
Set Building Simplified by Standardized Hookup Board
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. It eliminates all wiring from part to part and practically any type of circuit can be employed. Consequently the following of blueprints and diagrams can be avoided and the various items assembled by merely plugging them in the proper sockets in the board.

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.

Radio Makers Find New Uses for Sets
No longer is radio confined to furnishing parlor entertainment. Manufacturers have found numerous new uses for radio sets which promise to make them an even more important part of our everyday life.
RADIO, which most of us are accustomed to think of as a means of parlor entertainment, is rapidly being applied in novel ways as manufacturers seek for new methods of using sets.
