Radio Store Provides Free Clubroom for Wireless Amateurs
IN the back of a retail electrical store located in the skyscraper section of New York City, there is a unique club-room for radio amateurs. A full set of radio receiving equipment has been installed with an aerial on the roof. Apparatus can be tested out in actual practice, and the visiting amateur is given the privilege of taking any piece of apparatus from stock to connect up and use as he sees fit.
Life Size Radio Movies Are Coming
C. Francis Jenkins is inventor of the original movie camera and holder of more than 400 patents, many of them in the field of radiovision. He predicts for the near future life size radio movies and radiovision of news events which may be projected on theater screens at the actual instant they happen. Jenkins describes the present status of television and the lines along which he is working.

WITHIN a short time, possibly within a year, I expect to see movie screens showing life size pictures of news events as they are happening. We are working now on that problem. We may not be first to solve it, but it is only a question of time until some one does, and it is quite possible that we may be first.
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.
THE SMALLER THE BETTER: NEW DIMENSIONS IN CONVERSATION
In the eye of a needle above is a transistor switch that can turn on or off in ten billionths of a second. It is an example of the micro-miniature devices that Western Electric makes today for the new Electronic Switching Systems now being put into service in the Bell telephone network.
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.
Tired of dialing calls? Here’s an add-on that converts an ordinary dial phone for pushbutton signaling. The 5-1/4-inch sphere also has a memory for 10 frequently used numbers you can call with two buttons. Busy number? Just wait and push one button to repeat your call. Made by Pye in England.
Push one of Touch-a-matic’s 32 buttons and it places prerecorded phone numbers for you. An integrated-circuit memory (foreground) containing 15,000 transistors does the job. To store numbers, you push a “record” button, then the digits. Developed at Bell Labs, the new phones will appear in 1974.
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.
