The Pioneers

Since early 1906, several radio fans, as Bernardo Kayel, Juan Cámera, Alberto Vidal, Valeriano Durañona, Inocencio Illa, Oscar Oneto and Juan López experimented with airwaves. They built homemade crystal receivers in order to listen to the two stations that worked at that time.

The first of them was the wireless telegraph station installed in 1904 by the German company "Telefunken" which represented Mr. Ernesto Quincke. It was followed by the British "Marconi" installed in Punta del Este.
Meantime the Uruguayan government appointed Bernardo Kayel as "technical general inspector for wireless telegraphy", and he was commissioned to travel Europe and buy the first Telefunken telegraphy equipment.
Subsequently, the government resolves to close down the private stations, installing a coast radiotelegraph station to serve the ships that had "wireless" facilities. Opened in 1912, it was CWA, in the Cerrito de la Victoria.
Meanwhile, Valeriano Durañona, who was also a writer and journalist, was the first who installed radiotelegraph systems in the countryside, in addition to make lectures at high schools on the propagation of radio waves and the mysterious galena crystals.
Years later, in 1915, when Lee De Forest invented the first radio oscillator and amplifier valve, Claudio Sapelli, began to experiment with two of this valves sent to him by the inventor. Sapelli, were manufacturing crystal radios sets for the very few amateurs of that time. He, like other radio enthusiast enjoyed receiving Morse code beeps form the Cerrito station.
Graduated in Electricity at the Mathematics School worked in several companies until he joined the General Electric as technical foreman while another pioneer, Emilio Elena did so as management secretary.
And Sapelly was who convenced the General Electric directors to take to the country a "broadcasting" transmitter, that came here in 1921.
Mr Caludio Sapelli ideas were amazing for his time. For example in 1922 he makes the second transmission of a sporting event in the world (the first was in United States a year before), during a soccer game between Uruguay and Brazil for the South American Championship in Rio de Janeiro.
