volunteers, who at the time often numbered around 100 at any given time. There were some part-time paid staff who led the volunteers and who were also students. Livingston eventually convinced the university to take over a defunct commercial 100,000-watt station (WDTH) and to affiliate with National Public Radio. He also introduced the concept of listener support and began on-air fund drives to help fund the station's operations. The station became known as WDTH for several years before reclaiming its KUMD-FM call letters. Livingston served as the station manager for eight years. He was succeeded by Paul Schmitz, who was eventually succeeded (again) by Michael (Mickey) Dean, who was succeeded by Vicky Jacoba. The station was sold to the Duluth–Superior Area Educational Television Corporation on December 1, 2021, for $175,000, and took the callsign WDSE-FM.
