The miniFM transmitter building workshop is a cornerstone of my DIY Broadcast Class at the School of the Art Institute of Chicago. Since 2007, I’ve been taking the workshop on the road, giving workshops to a variety of communitie outside the school. Partici- pants in the workshops are assumed to have know knowledge of electronics or electronics construction. Over the course of three hours, participants build and operate their own FM radio transmitter that can boradcast any sonic content the participant desires over a small area. Along the way, I provide accessory information such as the physical nature of radio waves, the regulation and allocation of radio frequencies, examples of activist use of the radio medium, issues of legality and the FCC’s part 15 and creative uses for the airwaves, providing examples of contemoprary artists using the electromagnetic spectrum as an artistic medium.
