History

1951-1978: Foundations

Jaime Yankelevich, businessman and operator of radio station LR3 "Radio Belgrano", received the approval of the Perón family to import television equipment from the United States. The final approval came from Eva Perón, who, when informed of the importation of the new equipment, said "Sí, sí, todo muy lindo pero yo lo que quiero es que televisen el acto del Día de la Lealtad" ("Yes, yes, all very good, but what I want is for them to televise the acts of Loyalty Day"). With the support of Minister of Communications Oscar Lorenzo Nicolini and the Radio Belgrano executives, preparations were made to start the first television station in Argentina. Yankelevich importedBell equipment, DuMont cameras, and a horizontally polarized antenna initially mounted on the MOP Building. On September 24, 1951, Radio Belgrano announcer Fito Salinas was put behind a camera and backed by a musical group, and the first test transmissions commenced. On the first days of tests, televisions were set up in department stores in a 500-meter radius around the site, and the transmitter put out 500 watts of power, but the signal was ramped up and brought to 40 kW power. At that power level, reception was clear for 45 miles around.
