Superpower AM Radio in the United States: Why it Failed

By John F. Schneider W9FGH

The term “superpower” was used frequently in the early years of American radio broadcasting, but its exact definition was continually evolving. In 1923, superpower referred to the newly-authorized 1,000 watt “Class B” stations. By 1926 WGY, Schenectady, New York, conducted the first ever test at 50,000 watts. By 1930 WGY had conducted tests at 200 kW, a signal heard in Alaska and Hawaii. But that station was not alone. Many others were eager to explore the possibilities of even higher power: 500 kW! What happened to all that enthusiasm for superpower? John goes deep into this engineering and regulatory jungle that saw broadcast titans trying to use the FCC to dominate America’s airwaves.


Rocking the Stasi

By Scott A. Caldwell

In June 1961, Berlin was a divided city. Viewed from the outside, East Germany, which surrounded Berlin, represented a closed society, dominated by the secret police known universally as the Stasi. But East Germany was vulnerable to Western culture and political ideology through the medium of radio that could not be regulated by the Stasi or the ruling Socialist Unity Party, which resulted in an electronic war of the ether. Scott traces the course of this battle of the airwaves that lasted from the end of World War II to the 1980s and the end of the Cold War.


Radio Heroine: The Life, Work and Inventions of Hedy Lamarr

Georg Wiessala  

Hedy Lamarr was born in Austria in 1914 and rose to stellar fame in Hollywood as a film actress and as a multi-talented inventor. Georg looks at the life and work as his most favorite (and most overlooked) radio heroines, without whom today’s Wi-Fi, GPS and Bluetooth technologies would be impossible. He explains why The Guardian claimed, “Lamarr’s story is one of a brilliant woman who was consistently underestimated.”


Inside the VTVM: Lafayette KT-174 and PACO V-70

By Rich Post KB8TAD

The VTVM (vacuum tube voltmeter) was the standard instrument for measuring DC and AC for radio and television service shops from the late 1940s to the end of the vacuum tube era in the 1970s. The sensitivity of the typical service VTVM on DC measurement was 11 megohms regardless of scale. Specialty VTVMs such as the Hewlett-Packard HP-410 offered much higher sensitivity but were high-priced lab-quality instruments and not typically found in radio-TV service shops. Rich takes a close look at two amateur favorites from the era.
