Edge 88.1 (KDPS) was the student-run radio station of Des Moines Public Schools' Central Campus, on the air since 1953 and programmed by high-school students with a varied mix of Top 40, rock and hip-hop. It stopped FM broadcasting on 88.1 MHz in June 2025, when the district sold the licence, and its student programming now continues as an online stream. Formerly: KDPS.
