This map plots the location of FM commercial and pirate radio stations within London. The poster works in its own right as a piece of information design, but when connected to the modified radio it becomes part of the interface. Each map is made site specific by connecting only the stations that can be received in that location. This is done by drawing power lines in pencil on the back of the map, which conducts electricity from the radio to the front of the poster. Placing a metal contact onto each point enables us to listen to the sound broadcast live from that location.
