The station was inaugurated on January 24, 1924, at the presence of Argentinian president Marcelo Torcuato de Alvear Máximo Marcelo Torcuato de Alvear Pacheco (4 October 1868 – 23 March 1942), was an Argentine lawyer and politician, who served as president of Argentina between from 1922 to 1928.

Wireless Telegraphy
Wireless telegraphy or radiotelegraphy is transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term ''wireless telegraphy'' was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. It continued to be the only type of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Máximo Marcelo Torcuato de Alvear Pacheco (4 October 1868 – 23 March 1942), was an Argentine lawyer and politician, who served as president of Argentina between from 1922 to 1928. His period of government coincided precisely with the end of the postwar world crisis, which allowed him to improve the economy and finances of the country without major setbacks. He also stood out in the development of the automotive industry and the successful oil exploitation, with which he achieved an economic prosperity unknown until then for Argentina, and that was demonstrated with the great increase achieved in the GDP per inhabitant, whose index for the In 1928 he had reached the sixth position among the highest in the world. In the labor and social sphere, this period was characterized by a process of urban concentration in the Litoral and Greater Buenos Aires, in addition to the establishment of half a million immigrants; there was an increase in the middle class, a rise in real wag ...
