The station is owned by the University of North Dakota, but is operated and programmed by Prairie Public, and carries programs from NPR and Public Radio International. KFJM is currently the second longest lasting radio station in North Dakota, signing on a year after WDAY in Fargo.
KFJM signed on as KUND in 1923 on the AM dial as a college radio station for University of North Dakota, making it one of the first college radio stations and the second radio station to sign on in North Dakota after WDAY. Its frequency has changed throughout the years from 1310, 1440, and most recently 1370. In 1995, KFJY-FM signed on at 90.7 FM simulcasting on KFJM AM with a AAA format and jazz overnight. During April 1997, both stations went off the air as the floodwaters went through the transmitter. KFJY 90.7 was switched to KUND 90.7. KUND-FM then switched call signs with KFJM 89.3 FM after the flood.
KUND AM 1370 was sold to Real Presence Radio, a Roman Catholic organization, in 2004 to allow funding for a transmitter move which was completed on August 22, 2006. The call sign changed to KWTL, and it began airing Catholic programming from EWTN. On August 9, 2006, KFJM moved its transmitter from the University of North Dakota campus to a tower located in the Grand Forks industrial park.
