Radius Sketchpad is an ongoing monthly program on Wave Farm's WGXC 90.7-FM presented by the Chicago-based platform, Radius. The program features works originally produced for Radius, and is followed by an audio playlist selected by the featured artist.

Radius is an experimental broadcast platform located in Chicago, IL, USA. Radius features a new project each month with statements by artists who use radio as a primary element in their work. Radius provides artists with live and experimental formats in radio programming. The goal is to support work that engages the tonal and public spaces of the electromagnetic spectrum.

All Radius Sketchpad episodes and supporting materials are archived on Wave Farm's Transmission Arts Archive at transmissionarts.org. More information about Radius is available at http://theradius.us
