	Alexanderson alternator - Wikipedia, the free encyclopedia
		The Alexanderson alternator followed Fessenden's rotary spark-gap transmitter as the second radio transmitter to be modulated to carry the sound of the human voice.
		Until the invention of vacuum tube (thermionic valve) oscillators in the 1920's, the Alexanderson alternator was an important high-power radio transmitter, and allowed amplitude modulation radio transmission of the human voice.
		The last remaining workable Alexanderson alternator is at the VLF transmitter Grimeton in Sweden.

		Here Alexanderson learned principles that would guide him throughout his career: rather than simply tinker, he would always work out the mathematical and scientific principles that underlay the engineering of AC devices, and only then apply them by means of careful mechanical experiment.
		Alexanderson spent much of the next several years working to develop AC-powered long-distance trains, and he made a major contribution to the field both with his synthesis of the series and repulsion motors and with his development in 1907 of the shunt repulsion motor.
		Alexanderson’s talent had not gone unrewarded: between 1907 and 1910 his annual salary rose from $2,900 to $4,000.

	IEEE History Center: Alexanderson Radio Alternator, 1904
		The Alexanderson radio alternator was a high-power, radio-frequency source which provided reliable transoceanic radiotelegraph communication during and after World War I. Ernst F.W. Alexanderson (1878-1975), a General Electric engineer, designed radio alternators with a frequency range to 100 kHz and a power capability from 2 kW to 200 kW.
		Alexanderson made tests on special Swedish iron strips 1 1/2 mils thick in strong magnetic fields at frequencies up to 200 kHz.
		Dr. Alexanderson (1878-1975) was an electrical engineer with GE from 1902 to 1948.

	Radio Story
		The Alexanderson alternator was a popular model in its time, and today, only a sole operational example survives in the whole world.
		During WWII, Alexanderson alternators located in Hawaii, were the only reliable long-haul method of communicating from the United States west coast to the fleet submarines 24 hours per day, seven days a week.
		This is accomplished with a magnetic amplifier circuit (also an Alexanderson invention) that changes a coupled circuit from being non-resonant in a key down state to being resonant at key up state in order to absorb the radiated load.

	8. Alternator-Transmitter Development (1891-1920)
		High-speed electrical alternators was one approach used to generate continuous-wave signals, and by 1919 international control of the Alexanderson alternator-transmitter was considered so important that it triggered the formation of the Radio Corporation of America.
		Meanwhile, Ernst Alexanderson, the lead General Electric engineer for the original Fessenden alternator, continued to work on improvements, and eventually developed alternators with power ratings of hundreds of kilowatts.
		Years later, Alexanderson recalled how he obtained the assignment: 'The alternator was one of the inventions I had to make in order to hold my job!

	Winning Writers - Poetry Contests and Resources for Poets and Writers
		This month's critique poem, John Alexanderson's "At First Light," caught my attention because of its economical yet densely textured language, and its continuity with the tradition of classic Christian poetry.
		In the opening stanza, Alexanderson uses alliteration and assonance to intensify the sound of his words, lifting them beyond mere prose.
		In a more overwritten poem, such language might seem affected, but Alexanderson skirts that trap by using simple, short sentences that maintain the natural and direct style we expect from contemporary verse.

		Plans are for the last remaining Alexanderson alternator transmitter to broadcast a greeting on 17.2 kHz on the morning of Christmas Eve from Grimeton, Sweden.
		However, such a transmitter could not easily be scaled up to the power level and frequency needed for practical voice work, and Fessenden realized long before most inventors that pure, steady continuous-wave signals would be vital to the future of radio.
		A number of short-range experiments took place as early as the summer of '06, and by early December, an operator at NESCO's other station in Machrahanish, Scotland, was able to overhear instructions being relayed from Brant Rock to a technician at another site on the Massachusetts coast.
