Beginning the project in Valparaiso in 1935, on October 15, 1936, in Santiago, radio transmissions began at a frequency of 570 kHz on the Medium wave band.
Radio Agricultura was influential in making Mexican music popular in rural areas of Chile.
Its transmissions were famous for their coverage of the coup of September 11, 1973 and its military bands that were heard on national radio and television throughout Chile.
[citation needed] Also in the 1970s the dictatorship shut down smaller radio stations thought to be sympathetic with the former Allende administration.
Radio Agricultura has among its ranks several public figures, including Alejandro de la Carrera (press director until March 2014), Joaquín Lavín, Fernando Villegas, Cecilia Pérez, Sergio "Checho" Hirane, and Eli de Caso among others.
