LOW-POWER FM RADIO To help communities or organizations set up LPFM stations, nonprofit groups like the Prometheus Radio Project provide support in obtaining government licenses and also actually construct the stations. For construction endeavors known as “barn raisings,” Prometheus will send volunteers “to raise the antenna mast, build the studio, and flip on the station switch.” Shown here is the barn raising for station WRFU 104.5 FM in Urbana, Illinois.
