Today, Saturday 16 August, marks the 100th anniversary of one of Argentina’s most important AM radio stations, which in recent years has remained the national audience ratings leader. The station is LR6 RADIO MITRE (AM 790 KHz), with studios in the Autonomous City of Buenos Aires. Although the station was officially inaugurated on 6 November 1925, it formally began broadcasting on 16 August of that same year, identifying itself with the call sign LOZ. Some time later, on 2 February 1928, the signal was assigned to ‘Sociedad Anónima La Nación’, at that time owner of the ‘Diario La Nación’ newspaper, founded in 1909 by Emilio Mitre, and was christened ‘LOZ The Nation Broadcasting’. Its first studios were located in a building in the Buenos Aires neighbourhood of Flores. In the 1930s, the station changed its call sign and name to ‘LR6 Radio La Nación.’ During the presidency of Juan Domingo Perón, LR6 was nationalised and operated by the state, an intervention that continued until the advent of democracy in the early 1980s. In this regard, Resolution 441 of the former Federal Broadcasting Committee dated 30/07/1982 called for a public tender to award the LR6 signal (AM 790 KHz) to private hands, and by means of Decree No. 2008/83 dated 09/08/1983, the licence in question was granted to the company ‘Radio Cultura S.A.’, which operated the station until 1992, when it was acquired by ‘Radio Mitre S.A.’, a company belonging to ‘Grupo Clarín S.A.’, the largest media holding company in Argentina. Currently, LR6 RADIO MITRE has its studios located at 2668 Gral. Mansilla Street in the Recoleta neighbourhood; Telephone: (11) 3003-0790 and 5168-0790 (Listeners); Email: info@radiomitre.com.ar; Website: www.radiomitre.cienradios.com. It is officially assigned Category II on AM, equivalent to a power of 100 kW (daytime) and 50 kW (nighttime), and its transmitter plant is located at 3050 El Chasque Street in William C. Morris, Hurlingham District, Province of Buenos Aires (Coordinates: 34°34’53.5‘S, 58°40’10.4’W), where its 200-metre-high omnidirectional antenna is located. It also has a Category ‘A’ Complementary Frequency Modulation Service at 99.9 MHz, which went on air on 17 August 1985 and has been known as ‘La 100’ since September 1987, in addition to another FM station at 91.5 MHz, awarded by Resolution No. 4558-ENACOM/19, which is not currently operational. It is worth noting that it has an important network of stations in the interior of the country that rebroadcast both the AM and FM signals. RADIO MITRE has been a benchmark in Argentine radio broadcasting, with a history marked by important historical events and prominent figures in journalism, hosting and broadcasting.
