What’s What in Radio Today (Feb, 1930)

Meanwhile, in more modern times, the iPhone in my pocket has a six-axis gyroscope that is smaller than a grain of rice.

What’s What in Radio Today

by Jay Earle Miller

What is the screen grid tube? What does it do? What are the advantages of the condenser speaker? These are a few of the questions that occur to folk trying to keep abreast of developments. Mr. Miller, who attended the Chicago radio shows, here gives the answers.

I WENT to a furniture show the other day and saw some clever new adaptations of radio to home decorating.

And then I went to a radio show and saw the finest furniture exhibit in Chicago.

Eight Ring Radio Circus (Nov, 1946)

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 (Jun, 1938)

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.

What the New Domestic COMMUNICATIONS SATELLITES Will Do for You (Jun, 1973)

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 (Oct, 1930)

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 (Jul, 1937)

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 (Jul, 1937)

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.

New FM Auto Radio (Jun, 1960)

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 (Sep, 1956)

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.
