The station first went on the air with a 10-watt signal on May 1, 1978, after drawn-out deliberations with the Federal Communications Commission, which was licensing a few low-power FM stations at the time. The first home was in the belfry of the Walker Community Church in South Minneapolis. In 1984, the primary transmitter was moved from the roof of the Seward Co-op to the top of the Foshay Tower in downtown Minneapolis and upgraded to 125 watts. The studios moved from the church two years later, when it moved to the second floor of a Butler Drug store on Lake Street. In 1991, studios were built especially for Fresh Air Radio at Cedar-Riverside near the University of Minnesota, where it remains today. A 170-watt West St. Paul translator station went up in 1994 and was sold to Hmong Radio Broadcast, LLC in May 2020.
