OpenBroadcaster is a web-based, open-source system to run community radio and television broadcast transmitters with a simple web interface.


The initial concept was to develop a web based radio system to run emergency messages and public service announcements for export to Africa by using a windup radio designed by Trevor Baylis.[1] . It was part of a Yukon College[2] innovation project originating from Tagish Yukon Territory Canada.

On Labour Day weekend, 1997 CFET-FM 106.7FM was launched,[3] for the benefit of communities in Tagish, Johnson's Crossing and Marsh Lake, YT. It was a one-man operation, but local volunteers could record material for sending to the station via the internet for broadcast. The system was used for the community's local emergency population warning[4] for instantaneous relay of Yukon Forestry Service alerts for Wildfire[5][6] situations. 2004 CFET-FM Radio began using OpenBroadcaster for User Generated Radio followed by CJUC-FM[7][8] forming a Yukon network of radio stations. Similar models of indigenous community radio networks[9] are supported nationally for language revitalization.[10]
