Triumph of the Amateurs - The Transatlantic Tests of 1921
Early in the twentieth century Amateur Radio Operators had been exiled to the wavelengths shorter than 200 meter's as part of a power play by large communication companies and the US government to set aside what they thought were the most desirable radio spectrum for themselves, leaving the shortwave wasteland below 200 meters to hams, but in 1921 a small group of radio amateurs performed an experiment that proved hams really had the better end of the deal.
Ed Gable, K2MP, and I explore the Transatlantic Tests of 1921 in this presentation from the AWA Shares series
