From Chicago art collective Temporary Services comes a traveling portable pirate radio station:
The Audio Relay is an autonomous radio station plus a music and sound archive. It travels from city to city gathering and presenting the work of musicians, sound artists, documentarians, and people whose work can be listened to. The Audio Relay houses a 4 watt FM transmitter, a folding antenna, a 30 watt amplifier, two speakers, two drawers that hold up to 200 cds, a cd player, two solar panels on a detachable cover, one chair and has storage space for posters and other informative material.
The Audio Relay is compact and easy to move around. Its dimensions are 22 1/2 in. x 22 1/2 in. x 9 in. The Audio Relay can be set up anywhere. The solar panels provide some of the power. The Audio Relay can run off any international AC power source or, for remote locations, a 12volt car battery. The battery can be re-charged by the solar panels or by plugging the unit in to a wall outlet.
The Audio Relay can play music for an intimate audience as well as broadcast material in a radius of up to a mile away.Audio Relay designer, Brennan McGaffey, also constructs other environmental altering projects such as the Utility-intertied Signal Generation & Transfer which transmits an Extremely Low Frequency signal by using and altering the electromagnetic field surrounding the powerline network in localized areas of the city.
