Seventy-five years ago, American shortwave broadcasters were clearly gearing up for war, as shown by an article in the January 1941 issue of Popular Science.

The article reports that in 1930, there were only three short-wave stations in Europe, but by 1941, there were at least 40, with more being built all of the time. In particular, the German radio, financed by the government, was pumping out Hitler’s speeches on as many as six transmitters at a time. They were targeting South America in particular, and the Americans wanted to keep up. Two million dollars was being spent on new transmitters, and according to the article, the investment was paying off. America had previously had only two transmitters running 50,000 watts or more, WLWO of Crosely Corporation in Mason, Ohio, and WGEO, owned by GE in Schenectady, N.Y.

New stations coming online included WNBI and WRCA, owned by NBC in Bound Brook, N.J., WCBX in Wayne, N.J., owned by CBS, WCAB and WCAU in Newtown Square, Pa., Westinghouse stations WBOS in Millis, Mass. and WPIT in Saxonburg, Pa., WRUL and WRUW in Scituate, Mass., and GE stations KGEI San Francisco and WGEA South Schenectady, NY.

There were 2.1 million shortwave receivers in South America, and they were a major target for the U.S. signals. NBC reported that in 1936, it reeceived fewer than fifty letters a month from South America, but was then receiving 2500 a month. Most of them were reportedly full of praise and reported their disgust with the propaganda fed by European stations.

Shown here at the key of a clandestine transmitter somewhere in German-occupied France is American spy Virginia Hall.

Born in Baltimore in 1908, she had her sights set on a career in the foreign service, and landed a job as a clerk at the U.S. Embassy in Warsaw in 1931. Unfortunately, while hunting in Turkey in 1932, she accidentally shot herself in the left leg, which later had to be amputated. She found herself in Paris at the start of the war and joined a French ambulance corps. After the fall of France, she made her way to London where she volunteered for the British Special Operations Executive (SOE).  Her cover story was as a correspondent for the New York Post, and she spent 15 months in both Vichy and occupied France, helping to coordinate the activities of the French Underground.

In 1942, Hall escaped to Spain and then back to London. In 1944, she joined the U.S. Office of Strategic Services (OSS) and was returned to France. Since her artificial leg prevented her from parachuting in, she was landed at the Brittany coast by a British boat. Using a forged identification for Marcelle Montagne, she contacted the Resistance in central France and mapped drop zones for supplies and commandos.

She died in Maryland in 1982 at the age of 76.

Eugène Aisberg, 1946.

After a wartime absence, the January 1946 issue of Radio Craft carried an article by writer Eugène Aisberg.  While that name might not be familiar to American readers, Aisberg was a prolific author in the early days of radio, and wrote some of the best treatises on radio for the popular audience.  He was fluent in French, Esperanto, German, Russian, and English.

Aisberg was born in Odessa, Ukraine, in 1905, and lived most of his life in France. He was the director of the French magazine Toute la Radio and a prolific author of a number of books. His most popular book, which is still in print, is La Radio? Mais c’est très simple (Radio? But It’s So Simple!)  The book, currently in its 29th edition, an extremely solid background covering all aspects of electronics, and is written in a popular, easy-to-read style. While the book was ultimately translated into several languages, it was apparently never published in English.

The book consists mostly of a dialog between Ignotus and his uncle Curiosus, along with explanations by Professor Radiol, in which the characters explain in an interesting fashion all aspects of electronic theory.

Aisberg’s first radio book was actually published in Esperanto. Jen… mi komprenas la radion (“Now I understand the radio”).

1942 edition of Amélioration et modernisation des recepteurs.

During the war, under the noses of the occupying Germans, Aisberg published a book explaining how to pull in Radio London and other foreign stations. The technical title of the book, Amélioration et modernisation des recepteurs (“Improvement and Modernization of Radio Receivers”) was undoubtedly helpful in getting the book past the German censors.

While his most famous book was never translated into English, his later TV – It’s a Cinch was published in English in 1957. While analog TV is now an obsolete technology, the book is still an extremely interesting read, and the reader walks away knowing how the technology works.

The 1946 article, which marked his return to an American audience after the war, described a radio with automatic selectivity control.  The article also contains the following sidebar, which is a fascinating reminder of conditions prevailing in France immediately after the war:

Because of the conditions prevailing in Paris, instead of a check, Aisberg preferred payment for the article to be in the form of “chocolate, cocoa, toilet soap, shaving cream, corned pork, coffee, needles and thread, canned ham, and high-speed razor blades.”

Aisberg died in Paris in 1980.
