Moving NBC’s Flagship Station, 1940

By John F. Schneider W9FGH

     In 1927 WEAF, NBC’s flagship station in New York City, was one of the first stations in the US to operate at 50,000 watts. But the station was required to move outside the city to avoid overloading receiving sets of the day. Then it was discovered that the distance required also made it harder to receive in the city. It was a classic Catch-22. John describes the process engineers had undertaken to be heard.


Panoramic Radio and the Hallicrafters SP-44 Skyrider

By Rich Post KB8TAD

     Having a spectrum display on a radio today is taken for granted, but in 1938 in the run up to WWII, such a luxury was unheard of, until the Panoramic Radio Corporation developed a device that showed an oscilloscope display on a range of frequencies in the radio spectrum when hooked to the converter tube of a companion receiver. Rich explains how this works as he describes the restoration of this combination.

‘The Radio Historian’s’ 2021 Radio History Calendar’ by John Schneider W9FGH

Reviewed by Ken Reitz KS4ZR

     Two new publications available this month make great gifts for radio fans in your family or a nice treat for the radio historian in you. ‘QSL’ is an homage to the golden era of shortwave listening, from post-WWII to the collapse of the Soviet Union. With carefully preserved QSL cards and letters, Ronald Kenyon shows what it was like when nearly every country in the world was on the air and propagation couldn’t have been better. ‘The Radio Historian’s 2021 Radio History Calendar’ is John Schneider’s annual tribute to some of the most influential radio stations in the US. Curated scenes from various eras of US radio broadcasting history give more than just a snapshot of the times—styles, fashions, celebrities of the times and technology of the day are a feast for radio fans’ eyes.
