.AIR-TO-GROUND TV SYSTEM Transmits Combat Pictures on FM
Airborne military television crams a self-contained transmitting station into a small reconnaissance plane, then flies this ever-moving station over unpredictable terrain. Taking these adverse conditions into account, Admiral developed an extremely compact television system which uses FM transmission for the picture.
This seems like it would be incredibly imprecise. It seems like if you wanted to cheat, you could abstain from pressing the first button and then press the second to vote. You would essentially get counted twice. Try that trick with a really powerful transmitter and you could probably throw the whole vote.
.“TALK-BACK” for your RADIO
NO problem of the commercially sponsored radio broadcast is more vital than the determination of listener response. What percentage of people like a program and what per cent do not. If the president asked his radio audience to vote “yes” or “no” on an important question how valuable it would be if he could learn the trend of opinion on the topic by the next morning; and with no more trouble to the listener than the mere pushing of a button on his radio set.
.From Microphone to Your Home
ON THIS page our artist pictures every step in radio broadcasting from the studio performance to your ear.
Tons of complicated electrical broadcasting machinery work under full load in order to vibrate the diaphragm of your loudspeaker which, at most, weighs only a fraction of an ounce.
However, when you consider that many millions of loudspeakers all over the country are operated in unison with yours, and that broadcasting would be virtually worthless if the highest standard of technical excellence were not maintained, the vast expenditure in time, money, and machinery is amply justified.
.Self-Tuning RADIOS to be Fan’s Choice in 1930
Gone are the tinkerers who used to buy sets. Music with one dial whirl is wanted today. 1930′s sets will carry one dial or automatic tuning to be up to date.
THE new 1930 radio sets will be first of all. beautiful. The most marked change in trend in winter buying of radio sets, according to a large number of radio dealers, is that the emphasis has changed from interest in a radio set as a piece of machinery, to demand that it be a piece of furniture. In the past, most radios have been sold because the buyer wished to get things over the air. This condition still exists, but coupled with it is the fact that the buyer now also wants his radio to be handsome as well as practical.
.Radio Camera outfit lets the photo-minded girl snap a picture without missing her favorite radio show. It weighs less than 4 pounds, is 9-1/2 inches high.
Why don’t they just take their baby to the park with them instead? It has to be lighter than that receiver. And bringing a radio to the movies so other people can listen to your screaming baby is a swell idea.

This Baby Broadcasts When She Wants Attention. Mother And Father Can Hear Her On Their Own Portable Radio Set LITTLE Dianne Roxas is only two months old, but already she is a radio star in her own right. From the privacy of her pink and blue beribboned bassinet, she broadcasts daily over her own private “station,” airing her troubles over the ether to an “audience” distributed within a radius of a few blocks of her home in Brooklyn, N. Y. Little Dianne is probably the youngest “ham” radio operator in the world, having been at it ever since she was ten days old.
.Hearing-Aid Radio
This tiny radio adapter plugs into the side of a hearing aid, and now people who wear these gadgets have an advantage over their friends who hear normally. They can tune into their favorite program whenever they desire.
.Robot Production Line Makes 3 Radios a Minute
THE so-called “printed” radio sets are still new on the American scene, but they are rapidly becoming common items in England. A new factory near London is using a robot machine (above) which takes the plastic molding in one end and delivers the printed circuits from the other end at the rate of three a minute. It would take about 2,000 workers to do the same job by hand.
.Tank Maneuvers Controlled by Radio
Developments in the mechanization of the army is the installation of radios in tanks for the transmission and receipt of orders. Control of tanks in action, since they were first introduced by the British during the World war, has been at once an important and difficult task, hitherto performed by officers who walked beside the tank and signalled with flags—a duty both dangerous and unsatisfactory.

PSM photos by Robert F. SmithCOMMUNICATIONS are being revolutionized faster than you think. The humming wires beside the highways already are rivaled by new systems, capable of transmitting more spoken or written words and more still or moving pictures from coast to coast. The difference between these new systems and those of the past is as great as that between oxcarts and stratoliners.
