Christoph Lindenmaier has been a Community Radio activist since the late 70´s. From 1982 Lindenmaier was a developer of scientific and media-oriented apparatus (lab equipment, broadcast transmitters …) and free-lance consultant; consultant for technical, juridical, organizational and human-rights oriented aspects of non-commercial broadcasting. From 1986 to 1994 he was co-founder and head of Technical Commission of the European Federation of Community Radios (FERL) and did various surveys to assess the availability of FM-channels in politically difficult surroundings. He takes a more critical view of the digitalisation process in broadcasting and gives some insights to the technical implications. Simone Boria talked to him after the Radio FRO conference at the AEC at this years Ars Electronica Festival.
