The Amateur in the Making

By Walter Burnett

WHEN Marconi completed experiments a number of years ago, which made wireless telegraphy practicable, an unbelieving world sat up and gasped.

The wonder of his achievement lingered in the minds of many for a few days and then died. In certain young men, however, it created the spark of ambition, which flared up into an irresistible desire to enter into this new and practically unknown field. As a result nearly every city in the country boasts (or tolerates) its wireless amateurs.

The mystery constructor is wearing a mask? Huh?

World’s Smallest Complete Radio Broadcasting Station

THE City of Brotherly Love now boasts of the world’s smallest radio broadcasting station. Not much different in size and appearance from a household refrigerator, this station is accurate in all respects, operates entirely under its own power, and has a sending radius of two hundred feet with its 1/400th of a watt power plant. Its call letters are WEE, and it is owned and operated by the Tiny Broadcasting Company, operating on a frequency of 1,300 kilocycles.

The transmitter was designed and built by the Mystery announcer of WPEN, who recently won the title of the most popular radio announcer in a nation-wide contest.

Antenna Now a Loud Speaker

RADIO “freaks” or hearing of programs without apparatus, are reported occasionally; but are usually hard to verify. However, an occurrence at the Hilversum (Holland) station, reported by no less an authority than Dr. Balthasar van der Pol, in a letter to Nature, is well authenticated by competent observation.

Voices Across the Land (Feb, 1959)

The exact same quote about being assigned a phone number at birth is used in the Mechanix Illustrated article Your Telephone Of Tomorrow (Sep, 1956). If you haven’t read that one, be sure to check it out, it pretty much predicts modern cell phones.

Voices Across the Land

Night and day I keep singing—humming and thrumming:

It is love and war and money; it is the fighting and the tears, the work and want,

Death and laughter of men and women passing through me, carrier of your speech,

In the rain and the wet dripping, in the dawn and the shine drying,

A copper wire.

—Carl Sandburg

Under a Telephone Pole Screwdriver and splicing knife hanging from his belt, the telephone man keeps history’s happiest invention humming from coast to coast. He watches over 265 million miles of wire, waging war against storm, disaster and pesky animals that chew up or nest in his equipment. He hoists his lines over mountains with helicopters, shoots them across canyons with bow and arrow, strings them through dark conduits far beneath great cities. To every home and office, he gains ready entrance, exuding courtesy and helpfulness.




INSTALLED at the Chicago post-office is a new and striking machine for distributing mail. It looks like a monster typewriter attached to a belt conveyor, and is the first mechanical letter distributor to be adopted by any post-office.




WHAT happens when a submarine cable is dragged by a ship’s anchor is shown in the accompanying photographs ; this accident occurred to the New York Telephone Company’s connections between Brooklyn and lower Manhattan. A steamer, trying to make its pier, was carried too far by the swift current under the Brooklyn Bridge. Dropping its anchor, it caught the cables lying on the bottom beneath the bridge.
