KRNA (94.1 MHz) is a classic rock-formatted radio station licensed to Iowa City, Iowa. The station is currently owned by Townsquare Media. KRNA's studios located in the Alliant Energy Building in Downtown Cedar Rapids, and their transmitter is located west of Oxford. History In 1971, a group of University of Iowa students formed a company known as Communicators Inc. of Iowa that aimed "to put together a radio station with a major market sound in what was basically a small-to-medium market." At the time, FM radio stations in Iowa were primarily used for beautiful music formats or repeater signals for co-owned AM stations while popular music was played on AM stations. By 1974, Communicators Inc. of Iowa had been renamed KRNA, Inc., and the company was granted FCC approval to begin broadcasting. KRNA began broadcasting at 93.5 FM on October 4, 1974. (KRNA later moved to 93.9 FM in 1979 before moving to its present 94.1 FM at 9 a.m. on October 14, 1991.) By January 1975, Arbitron telephone surveys showed that nearly half of local radio listeners were tuned into KRNA. As part of its "major market sound", KRNA pre-recorded its commercial announcements during a time when most commercials were read live on the air, and it also broadcast 24 hours a day while other radio stations signed off during the overnight hours for equipment maintenance. When the early 1980s rolled along, KRNA began tweaking its Top 40 format with a more rock connection. In June 1985, the station dropped its rock-leaned Top 40 format for AOR. In 1994, KRNA purchased KQCR (102.9 FM) in Cedar Rapids, the area's longtime dominant CHR station, to create the area's first radio duopoly. After reformatting KQCR as country music station KXMX, owners Rob Norton and Eliot Keller agreed to sell KRNA and KXMX to Capstar Broadcasting in 1998. While the KRNA sale was successful, Capstar terminated the agreement to buy KXMX. (Norton and Keller kept KXMX, renaming it KZIA and changing the station's format to contemporary hits.) AMFM, Inc., acquired Capstar in 1999, and Clear Channel Communications acquired AMFM in 2000; however, KRNA was sold to Cumulus Media that year since Clear Channel already owned a group of stations in eastern Iowa. In 2004, KRNA's format shifted from classic rock to active rock, adopting the nickname "Real Rock 94.1". That year, former KFMW morning DJs Lou Waters and Scott Steele became the
