Northern Public Radio’s history began in 1954, when WNIU signed on the air at 10 watts. Broadcasting only a few hours each day, programming included announcements of campus events, lectures and music. In 1964, transmitting power was increased to 2,500 watts, allowing WNIU to serve DeKalb, Sycamore, and most of the rest of DeKalb County. Programming evolved as well, to focus more on music and local news and less on campus information.
