More Radio!

Although I am not a subscriber to your magazine, I never miss a copy of it at the newsstands. Your mag is one of the best on the market, and yet there are ways of improving it.

To be a radio operator, set builder, service man , or what have you, you must have patience, We, the radio hams of the United States, have been patient long enough while you let the greedy chemists hog all the articles. For the last four or five months I haven’t seen a worth-while radio article, while look at those good ones that were published last year.

Take Your Radio on Your Motor Camping Trip

Edited by CHARLES MAGEE ADAMS

WITH the advent of summer, the thoughts of many are turning eagerly vacation-ward. For a goodly proportion of car owners this means anticipation of a long interesting motor trip, with the added pleasure of camping en route. To the radio contingent the attractive prospect of such an expedition may be tinged with regret at leaving behind the trusty receiver and the programs it brings nightly. But that need not be the case. Read the rest of this entry »

That’s quite a portable power unit there. Then again it’s also a pretty big camera. I think it’s funny that they always use female models for these things. While I get the “it’s so easy a woman can do it!” angle, it tends to make big things look more unwieldy.

A Repeating “Flashbulb”

THE dream of photographers for years, here at last is a repeating “flashbulb”— and it is an extremely high-speed flashbulb, too. Whereas ordinary flashes take photos at from 1/20th to 1/200th of a second, this shoots at 1/20,000th! Made by Edgerton, it uses a portable power unit.

Germany Is Going Modernistic in Designing Unique Eating Places

GERMANY, one of the homes of modernism, is setting a rapid pace for architects and designers everywhere, this odd, mushroom shaped building being but one example of their efforts to attain the novel and unique in architecture.

This building, which houses a restaurant overlooking the Rhine River, is three stories high. Administrative offices, checking rooms, washrooms and the kitchens occupy the two lower floors. The upper floor contains private dining rooms, bar room and public dining balcony that hangs out over the river.

Yet another ridiculous debate we seem to be having verbatim almost 50 years later.

About People

Facts, foibles, fallacies and fascinating findings about your own and the opposite sex.

• WEATHER PARADOX Offhand you would think that on dark and dreary days people would be more likely to be late to work than in good weather, simply because such days offer little incentive to action. But oddly enough just the reverse appears to be true. Studies have found that instead of dawdling over their morning coffee and delaying their departure on bad days, both men and women get off to work more promptly than they do in fair weather.

Making SUBMARINES SAFE for SAILORS

by ROY DEAN

NINETY-NINE men who have perished at the bottom of the sea in the thirteen American submarine disasters since the E-4 went down off Pearl Harbor, Hawaii, on March 25, 1915, may not have died in vain. Spurred on by their heroic sacrifice —and particularly by the loss of the 73 who perished in the S-51 off Block Island and the S-4, rammed and sunk by the Coast Guard Destroyer Paulding off Providence— the navy has at last perfected a complete group of submarine rescue devices which are expected to save all who escape the first rush of water and find refuge in watertight compartments.

Science Presents Dumb Man With a Removable Voice

C. F. LORENZ, a Wichita Falls, Texas, auditor who was dumb for months as the result of an operation is now one of the six persons in the entire world who can place his voice in his pocket after completing a conversation. Some time ago Mr. Lorenz was stricken with caricinoma or cancer of the larynx which is often called the human voice box. It was necessary to have the larynx removed and as a result he became dumb.

THE BASEBALL – A Precision Product

IF YOU’RE a big league slugger and “hot,” you may loop that baseball against the stands, burn it over third base or sock it out of the park. But hot or cold, you still won’t “knock the cover off.”

For the baseball is a precision product, solidly designed by fine workmanship to take the hardest swat. The official baseball’s core is made of topgrade cork and rubber carefully cushioned in three windings of wool and a binding of cotton. Read the rest of this entry »

I wonder how many Japanese spies the internments actually prevented from acts of espionage. My guess would be close to zero. Besides the blatant racism, xenophobia and violation of civil rights, it just seems like a ridiculously inefficient way to stop espionage.

SMOKING OUT JAP SPIES

by Don Eddy

If you are not yet awake to the peril of invasion on our west coast, this article will give you a jolt. For weeks Mr. Eddy has been hot on the trail of enemies in our midst. He has seen U.S. agents uncover nests of spies working with short-wave radio, blinkers, signal flags, and carrier pigeons. And we’ve been handling these deadly snakes with kid gloves! Eighty per cent of them slip from the Army’s grip through legal loopholes. With our shores in imminent danger, this article is a challenging call for action.

JUST before midnight on last December 22, a young California farmer and his girl were sitting in a parked automobile at the brink of a cliff overlooking the Pacific Ocean. It was a clear, crisp night.

Novel Limousine-train Resembling Locomotive Travels the Highways

A THEATER corporation has placed on the highways a “trackless locomotive,” which is also called a limousine train. The car is equipped with radio receiving sets and microphone for speaking. It was especially designed and built at a cost of $25,000. It has a special four-speed transmission, a special clutch and a straight-eight motor.
