Radio Sutatenza

Radio Sutatenza was a Colombian radio network which broadcast cultural and educational programs between 1947 and 1990. It was the first community radio station, conceived as a direct response to the high levels of illiteracy in rural communities at the time.
Radio Sutatenza was established in 1947 by the Catholic priest José Joaquín Salcedo Guarín in the Colombian town of Sutatenza, located in the Tenza Valley, Boyacá, who founded the "Escuelas Radiofónicas" (Radio Schools). Radio Sutatenza was conceived as a direct response to the high levels of illiteracy in rural communities at the time. Radio Sutatenza was granted a license from the then Colombian Ministry of Communications with the call sign HK7HM.
Initial broadcasts used a 90-watt transmitter manufactured by the priest's brother. In 1948, General Electric donated 100 radio sets and a 250-watt transmitter and, years later, donated a 1 kW transmitter. By 1978, Radio Sutatenza was the largest Latin American radio network for rural education, with a power of 600 kW.
It started with programs where the farmers performed local music. Later, Father Salcedo, with the support of a Catholic organization called Acción Cultural Popular – ACPO – and the rural community, developed a series of courses on math, writing, agricultural instruction, health and sanitation, among other subjects that aimed to diminish illiteracy and improve farmers' life quality. Even though it was not a Catholic radio, it was mainly funded by the Church and it was blessed by Pope Paul VI during his papal visit to Colombia in 1968. Radio Sutatenza freely talked about topics that were not strictly within in the church's ideas, such as family planning.
Radio Sutatenza grew to the point where it aired 19 hours of educational programs per day, covering 687 towns and four main Colombian cities at the time. It distributed 6,453,937 handbooks, answered 1,229,552 letters from students, it created a weekly newspaper called "El Campesino", and educated about 8,000,000 farmers around the country. It also became a model for other rural education initiatives in Latin America, such as Fundación Radio Escuela para el Desarrollo Rural (FREDER) in Osorno, Chile; Instituto de Cultura Popular (INCUPO) in Reconquista, Argentina; Escuelas Radiofónicas Populares de Ecuador (ERPE); Radio Onda Azul in Puno, Perú; Asociación Cultural Loyola (ACLO) in Sucre, Bolivia; Radio Occidente in Tovar, Venezuela, and Escuelas Radiofónicas de Nicaragua.
Despite its important role in improving the education of millions of people, by the late 1980s Radio Sutatenza was on the verge of bankruptcy and ended being sold in March 1989, with its powerful transmitters, to Caracol Radio, the largest radio network in Colombia. The last broadcast was made on 17 February 1990. The rest of the literacy project by ACPO folded by 1994.
