Eight Ring Radio Circus
TO AM and FM a new kind of broadcasting has been added—PTM, pulse time modulation. By transmitting eight or more different programs at one time on one frequency, it may help solve the traffic problem in the radio spectrum.
PTM was developed to meet the need for crowding more broadcasts into the ultra-high-frequency range between 300 and 3,000 megacycles. These microwaves are relatively immune to fading and static, but travel only along a line of sight, limiting reception to the horizon of the transmitter.
Home Newspapers by Radio
Your Home a Silent “Press Room” . . . Automatic Facsimile Reproduction . . . Latest News by Breakfast Time . . . Bulletins Are Now Being Broadcast
A PRIVATE newspaper with any spot in your home as the press room, the world’s best editors and reporters on your staff, is available today to anyone in the United States possessing an ordinary radio receiving set. No thundering press will deafen you while your newspaper is being printed; instead, equipment contained in a small attractive box will silently print your “latest edition” while you sleep, completing it in time for reading at breakfast.
I love it when writers with expertise in one area just throw in huge advances in other technologies as a possible result of another. Eg: What does a 3-D virtual conference room have to do with satellites? Would it not work with wires?
What the New Domestic COMMUNICATIONS SATELLITES Will Do for You
Canada’s pioneering Aniks, and U.S. successors, are introducing the revolutionary innovation of overland telephone-and-TV relays in the sky. They promise bargain rates for long-distance phone calls, picture phones that everyone can afford—and better television programs, by way of novel kinds of TV networks

On Jan. 11, 1973, Rudy Pudluk, community manager of Resolute on a Canadian island above the Arctic Circle, made a long-distance phone call to Ottawa. The English-speaking Eskimo chatted with Gerard Pelletier, Minister of Communications, and with David Golden, president of Telesat Canada, whose system carried his voice across the frozen North.
How Ingenious Sound Producing Devices Fool Radio Microphone
You can’t always believe what you hear over the radio—the picture above proves it. Sound producing machinery of a large chain broadcasting company is shown. Thirty-three separate sound effects arc produced by the cabinet before which the operator is sitting, but in addition to this a large number of individual devices are employed, including numerous bells of various tones, a cigar box with a pulley and piece of string to simulate the sound of a curtain being drawn in a theater, oar locks used in acts calling for a rowboat, and a pillow to be struck with slats to produce the thudding effect of a prize fight blow against human flesh.
PLANES’ RADIO MESSAGES “CANNED” FOR DISASTER RECORD
RADIO communications between plane pilots and airport dispatchers are now permanently recorded on wax cylinders by an electrical machine recently installed by the U. S. Bureau of Air Commerce at a California landing field. Reports made by pilots and orders given by dispatchers, kept on file in record form, are thus available to examiners investigating the causes of any accident to a plane.
WORLD RADIO BATTLE LOOMS
Priceless radio frequencies will be doled out at international conference to be held in Cairo early in 1938.
by Roland C. Davies
AS THE smoke of foreign conflict rises above the horizon, students of world affairs realize that international broadcasting is perhaps the most potent arm of propaganda to dump nations into the inferno of war or to maintain peace.
Almost daily the press tells how foreign nations are using that marvel of modern science to tell the world via short-wave radio of their nationalistic aims, armed strength and economic prestige.
THIS is everyone’s War… if you are not able to serve in the Army or Navy, you can serve on the production front. Elmer is doing his duty by leaving his non-essential position and taking a job in the war plant.

New FM Auto Radio
OUR recent survey “FM Radios for Your Car” (December 1959) contained several reports from leading auto radio makers which stated flatly they had no plans for marketing an FM auto radio. Motorola was one of them. In spite of their former stand—or perhaps because of our article—Motorola is now mass producing the FM-900, a mobile radio that tunes 88-108 mc.
KENNEDY ANTENNAS… Probe the secrets of inter-stellar space
Somewhere in the nearly empty reaches of outer space, two hydrogen atoms collide. After a 100-million year journey at the speed of light, the signal generated by that accidental collision reaches a super-sensitive radio telescope antenna in Massachusetts and is recorded — and so one grain more is added to man’s knowledge of the universe.
You probably need to attract a lot of listeners-in to earn that four-figure income!
Could You Become a Radio Star?
By Alfred Albelli
If you have ability as an entertainer, along with a good radio personality, fame and fortune may await you if you can pass the radio audition test, as described here.
NO DOUBT everyone would get a great thrill hearing his name announced over a network of powerful broadcasting stations as the artist who will next entertain the vast multitudes of listeners-in with a song, a string of jokes, or a speech treating subjects of interest to the nation. And no doubt, also, everyone would get even a greater thrill out of receiving each month a salary and royalty check of the generous four-figure proportions that most radio entertainers pull down.
