Emerson Radio & Phonograph Corporation
Compact Model 25
World’s Biggest Selling Little Radio

Richard Arnold
From 1924 to 1932 Emerson Radio and Phonograph Corporation distributed radio receivers bearing the name Emerson through many diverse channels, including department and sporting goods stores. In 1932, Emerson began to specialize in small receiver sets for home use. One of these sets was the now very collectible and desirable model 25. This is the first true compact radio.

If Not “Television,” Why Not “Facsimile?”
So many people ask: “Are we ever going to have television in our homes?” Instead of replying, the Editors ask another question: “How would you like to have an attachment for your receiver that would print the original strips of text and illustrations shown on these pages?”

New Styles in Broadcast Studios
The networks and the large individual stations throughout the United States are investing heavily in modernized and enlarged studio quarters.

Hollywood Goes Radio
Mystery plays, comedies, color-movies, these and many other types of motion pictures have utilized radio in some form to round out the script or the staging. Radio finally came into its own, though, last month, when Paramount Pictures released "Arkansas Traveler," and MetroGoldwyn-Mayer sponsored "Pygmalion." These two top-flight sound motion pictures depend, in the first instance, on radio broadcasting, and in the second, on sound recording, as the main theme.

Who Invented the Superheterodyne?
By Alan Douglas
Of E.H. Armstrong's four principal inventions—regeneration, superregeneration, the superheterodyne, and frequency modulation—the superheterodyne has always seemed one of the least controversial. "Everyone" knows that Armstrong invented it. He devised it during World War I, patented it shortly afterward, sold his patent to Westinghouse who cross-licensed RCA and the radio industry, and that was that. Some Frenchman named Lévy claimed he was first, but whoever heard of him?

Is International Broadcasting Just Around the Corner?
Radio engineers who are working to develop the dream of worldwide interchange of radio programs into an actual fact today are the adventurers of broadcasting. The results of their efforts are felt all through Europe, in far-away Australia, in South America and in South Africa. The American radio listener gets occasional glimpses of the fruits of their experiments when a program originating in a foreign studio is picked up and rebroadcast by an American transmitter on a National Broadcasting Company network.

Laboratory Tests in High-Speed Production
From bare floors to the production of more than 5,000 precision-tested radio receivers per day by 13,000 employees is in truth an accomplishment, but when it is done in the brief span of twelve weeks it establishes what is believed to be a new record for the radio manufacturing world. Who can say that such an achievement lacks thrills throughout every step of the transition?

40 years of Television
When I wrote in December, 1909, what was probably the first technical television article to appear in print--"Television and the Telephot," for my former magazine, MODERN ELECTRICS, even I did not foresee all the coming wonders of television. As I write these lines almost 40 years later, television has finally arrived--after many false starts.

Radio That Fixes Itself

World’s Largest All-Wave Set
The thrills of all-wave listening are no longer a novelty. The great enjoyment of tuning-in the world in your own home is now a commonplace. So much so, as a matter of fact, that fans are bound to miss the universal program fare when away from home on business or pleasure trips. There is now an indication that leading hotels throughout the land, in cognizance of the allwave radio trend, may follow the suit of the famous Hotel Waldorf-Astoria, of New York, in converting centralized radio systems into allwave program relay plans.

KDKA: Radios New 500 Horsepower Voice
In the amazing manner of what may some day be known as the "radio decade," our erstwhile pioneer and infant commercial broadcaster, KDKA, has achieved the ripe old age of ten and acquired a 500 horsepower voice. It seems hard to realize that 400,000 watts of power have grown from the feeble hesitant 100-watt transmitter that undertook the task of sending news to a few eager listeners on that momentous evening of the Harding presidential election.

German Television in 1935
While America is still of the belief that television has not advanced sufficiently for general use, England and Germany are now endeavoring, through the aid of their respective governments, to make television as popular as broadcasting. Other European countries are following in their footsteps, and it can be truthfully said that Europe is now in the throes of "television fever."
