Voice Silencer on Telephone Lets You Talk in Secret
Your telephone conversation can be made inaudible to others in the same room if the phone is equipped with a new mouthpiece that prevents sound from escaping. It is easily attached to any hand instrument and fits snugly around the speaker’s lips. There is no distortion of the voice. Part of the midget “telephone booth” telescopes to fit the standard cradle phone.

What Are the Facts About FM? (Nov, 1940)

What Are the Facts About FM?

A few years ago, prominent radio engineers “proved” by mathematical and other means that the periodic banging and crackling of static in your loudspeaker could never really be eliminated. They were wrong. For the development of a system of radio broadcasting known as FM (frequency modulation) has not only conquered the static bugaboo, but has given birth to other innovations that may well cause a revolution in America’s $4,000,000,000 radio industry. What are the facts about FM? This article answers the questions most frequently asked.

“Paddle Wheels” Form Television Aerial (Feb, 1940)

“Paddle Wheels” Form Television Aerial

No matter what you guessed to be the purpose of the windmill-shaped thing above, you’d probably be wrong. Actually, it’s the newest fashion in television transmitting antennas. Just completed for a broadcasting station at Los Angeles, Calif., the big aerial measures sixty feet long and will be mounted vertically.

Tenants Run Apartment Network (Jul, 1940)

This is so cool. I wish Les Paul would start a private radio station in my building!

Tenants Run Apartment Network
TO ENTERTAIN friends and neighbors in a New York apartment house, a group of professional radio performers operates a unique basement “broadcasting” station. Every Friday and Sunday evening, led by Les Paul and Earnie Newton, they go on the air from their homemade soundproof studio near the furnace room. Programs go to all the apartments through a two-wire ground and aerial system which had been built into the structure and previously never used.

Radio Amateurs to the Rescue in Florida Hurricane (Nov, 1935)

Radio Amateurs to the Rescue in Florida Hurricane

During disasters radio “hams” come to the rescue. They keep in touch with lonely outposts, with explorers, arid like sentinels in the night guard against death.

by Clinton B. De Soto

WHEN a roaring hurricane swept through Florida in September, unknown amateur radio operators became heroes in the midst of death and destruction. Through howling wind and pelting rain they tapped away on their low-power transmitters when telephone, telegraph, and powerful broadcasting stations failed.

Their dots and dashes—the language of the radio amateur—hurtling through the ether flashed to the rest of the world news of the disaster and set the great task of relief into motion.

Do Wild Radio Waves Cause Air Disasters? (Jul, 1933)

Do Wild Radio Waves Cause Air Disasters?

Millions of horsepower of high-frequency electric energy, running “wild” in the air, may be the cause of mysterious disasters to aircraft, such as the loss of the Akron, the dirigible R-101, Knute Rockne’s airplane, and scores of others. How these amazing currents affect not only airplanes but your body, your home, and any objects that fail in tune with them, is explained in this unusual article on the unseen menace from the sky.

by BURTON MANFRED

THE radio experts of the United States Navy have recently completed a series of astounding experiments, experiments that prove far beyond the shadow of human error that there is a new menace in the sky. Hour after hour, day after day countless thousands of horsepower of high-frequency electric energy is being pumped into the air by great radio stations and other high-frequency machinery which has become a part of our civilization.

Only an infinitesimal speck of this prodigious output of energy is consumed by the radio receivers of the world. What happens to the rest? Does it become a wild and roving source of death and destruction or does it rush into the frigid voids of space never to return to the earth?

Your Telephone Of Tomorrow (Sep, 1956)

Usually old articles of the form “Your x of tomorrow” be it house, car, phone, city, plane, etc are full of ideas that are wildly off the mark or just plain ridiculous. This article about the future of phones is remarkable because virtually everything in it has come true. Worldwide Direct Touchtone Dialing, Transistorized Switching, Audio/Video data compression, Voice Recognition and rampant miniaturization. All true. Not to mention that a tiny, touchtone, color videophone you can watch TV on is a pretty accurate description of my Motorola RAZR.

I also love the idea that everyone will get a phone number at birth and keep it for the rest of their life. If you call someone and they don’t pick up, you’ll know they’re dead. Or perhaps just sleeping.

Your Telephone Of Tomorrow

Future may bring push-button dialing, videophones, direct calls anywhere on earth and pocket-size sets.

By Robert G. Beason

ON SOME night in the future a young man walking along Market Street in San Francisco may suddenly think of a friend in Rome. Reaching into his pocket, he will pull out a watch-size disc with a set of buttons on one side. He will punch ten times. Turning the device over, he will hear his friend’s voice and see his face on a tiny screen, in color and 3-D. At the same moment his friend in Rome will see and hear him.

The disc will be a telephone, a miniature model equipped for both audio and video service. Back in 1952, Harold S. Osborne, retiring chief engineer of American Telephone & Telegraph, envisioned this tiny instrument as the ultimate shape of the phone. In the future, said Mr. Osborne, a telephone number will be given at birth to every baby in the world. It will be his for life. When he wants to call anyone, no matter where, he will merely push the buttons on his Lilliputian phone.

Ad: HER BIGGEST JOB IS WAR (May, 1945)

HER BIGGEST JOB IS WAR
There has never been a time when the work of the telephone operator has been so important as right now.
For there are more Long Distance calls than ever before. More are in a hurry, particularly the urgent calls of war.
Calm in emergencies, capable and courteous, the telephone operators are earning a nation’s thanks for a job well done.

BELL TELEPHONE SYSTEM

When you’re calling over war-busy lines, the Long Distance operator may ask you to “please limit your call to 5 minutes.” That’s to help more calls get through during rush periods.

President Gets Telegraph Key (Jul, 1939)

I was not aware that F.D.R gave many speeches via telegraph. I must say his fireside chats would have lost something if they were entirely composed of dots and dashes.

President Gets Telegraph Key
A new official telegraph key for the White House, for use when Presidents officiate by proxy at distant ceremonies, has been presented to President Roosevelt by Western Union.
