What began as a tool for civilian self-defense in the combat zones during El Salvador's civil war evolved into a means of self-expression that helped define the type of democracy that would govern the country in peacetime. Community radio became the focus of a struggle for participatory democracy in the last decade of the twentieth century, pitting the market logic of communication that had been the dominant model against a diametrically opposed concept of the purpose of communication. Harking back to the lessons that Archbishop Arnulfo Romero taught through YSAX, the radio station that defied the military dictatorship in the late 1970s, and drawing on traditions that refugees developed in exile, community radio stations mobilized local and international support; tested constitutional law in the courts; and, finally, resorted to subterfuge to provide an outlet for alternative communication. By linking together in the Asociacion de Radios y Programas Participativas de El Salvador (ARPAS, Radio and Participative Programs Association of El Salvador), they defended their listeners’ rights as community rights. Their struggle illuminates the limitations of trying to understand a communication system with a logic that is alien to the media producers and their audience. [ABSTRACT FROM PUBLISHER]
