Alexanderson 200 kW motor–alternator set installed at the US Navy's New Brunswick, NJ station, 1920. In 1904, Reginald Fessenden contracted with General Electric for an alternator that generated a frequency of 100,000 hertz [citation needed] for continuous wave radio. The alternator was designed by Ernst Alexanderson.
The transmitter chosen was the 200 kW version of the Alexanderson alternator, invented by Swedish-American Ernst Alexanderson, manufactured by General Electric and marketed by their subsidiary RCA. This consisted of a huge rotating electromechanical AC generator ( alternator ) turned by an electric motor at a fast enough speed that it generated ...
