The station began in 1973 with a low-power signal that could only reach a portion of St. Louis Park High School; during this period, the station used the call signs WHAT, WSLP, and KTS. In 1977, the Federal Communications Commission (FCC) granted the school district a license to operate a 10-watt radio station, which took the call sign KDXL. KDXL operated at 91.7 through 1985; it changed frequencies so that it would not have a frequency close to KQRS-FM.[3]
Independent School District #283 voted to shut down KDXL on June 25, 2018;[3] the following day, it informed the FCC that the station would cease operations on July 1.[2] The license was cancelled on July 16, 2018.[7]
