 As a result, the station's original call sign, KUMR, was changed to KMST on July 16, 2007, as a reflection of the university's forthcoming name change.Until 2017, KMST broadcast from studios in the basement of the Curtis Laws Wilson library on the UMR/Missouri S&T campus.Effective July 1, 2017, the station (including its Lebanon translator) was transferred to the University of Missouri-St. Louis and became part of the St. Louis Public Radio network, airing the same broadcast as the St. Louis frequency.
