This site is for the making-of documentation for the Intermod Series. The main intermod website can be seen here. Intermodulation occurs when two or more signals mix generating a new or modified signal. Launched in 1999, the Intermod Series engages through interference. Methods of propagation include altering the electromagnetic field surrounding the electric-power grid, FM radio and boosted CB radio transmissions, launching rockets in the city to alter the atmosphere, and a spotters’ skywatch network and purging event. Developed to have the potential for interaction, the projects are distributed with mailers, 1-800 numbers, embroidered patches and stickers, radio monitoring frequencies, or online forums and journals. A more casual intermod discussion can be found here.
