The OpenHPSDR (High Performance Software Defined Radio) project dates from 2005 when Phil Covington, Phil Harman, and Bill Tracey combined their separate projects to form the HPSDR group.[1] It is built around a modular concept which encourages experimentation with new techniques and devices (e.g. SDR, Envelope Elimination and Restoration) without the need to replace the entire set of boards. The project has expanded from the original group, and several additional people have been involved in recent HPSDR module designs.
