- Alexanderson_alternator abstract "An Alexanderson alternator is a rotating machine invented by Ernst Alexanderson in 1904 for the generation of high frequency alternating current for use as a radio transmitter. It was one of the first devices capable of generating the continuous radio waves needed for transmission of amplitude modulation (sound) by radio. It was used from about 1910 in "superpower" longwave radiotelegraphy stations to transmit transoceanic message traffic by Morse code to similar stations all over the world, until it was replaced in the 1920s by vacuum tube transmitters. It is on the list of IEEE Milestones as a key achievement in electrical engineering.".
