Law No 9612/1998 deals with community radio broadcasting, sound stations belonging to foundations or associations representing a public contained therein, living in a neighborhood or united by a social cause and that the station presents itself as a spokesperson of these people. It has to operate with a maximum power of 25 watts ERP and its tower will have the limit of 30 meters. These technical characteristics delineate a portion coverage of an urban area, a partial coverage in the municipality. As said, the community broadcaster has a cultural function, there can be no explicit commercial breaks but cultural supports of the content of the grid. Programming times can not be sold to third parties and broadcasting to other stations is prohibited (going against the idea of a "community radio").
