WEFT (90.1 MHz) is a listener-supported community radio station in Champaign, Illinois, founded in 1981 and owned by Prairie Air, Inc., a not-for-profit corporation.
In 1980, WEFT began to broadcast on the local cable TV network and acquired studio space at 113 N. Market Street in Champaign.
In 1988, WEFT acquired a 10,000–watt transmitter and new broadcast antenna designed for a new transmission site located on a hill northwest of Champaign.
This move extended the broadcast coverage area significantly with the signal reaching up to 40 miles (64 km).
The reduced power to the east is required to avoid interference with a neighboring station located in Indiana.
