The station began as WCCO-FM in 1969. It was the FM counterpart of local powerhouse AM 830WCCO, owned by Midwest Communications. But it was hampered by its limited signal of only 2,700 watts. It had to temporarily transmit from the Foshay Tower at reduced power pending the completion of the Telefarm tower facility in Shoreview. It carried programming separate from the AM, with a mix of Beautiful Music and MOR album cuts and soft vocals, not unlike the pre-rock KQRS. The station later added two DJ shifts separate from the AM, hosted by Denny Long and Lou Lattson, playing a free-form rock music format, which included some underground rock tracks, along with full-service elements such as news and weather. Until 1973, the station only operated for the minimum amount of time required to keep the license. But in August 1973, when the transmitter was upgraded to full power, at 100,000 watts, a broad-based music format was launched. By 1975, the format evolved to adult contemporary music, though WCCO-FM continued to play deeper album tracks than most AC stations. In that same year, WCCO-FM picked up the syndicated "Dr. Demento Show" for weekends. Personalities included Paul Stagg, Carl Lensgraf, Terri Davis, Tom Ambrose, Curt Lundgren, Johnny Canton, Peter May and Pat O'Neill. Tim Russell, who went on to be a cast member on NPR's "A Prairie Home Companion," hosted middays and created memorable characters like traffic reporter "Captain Buzz Studley."
Switch to top 40
WCCO-FM was a modestly successful station until new IDS Center transmitters for competing stations were built in 1979. That caused interference to the WCCO-FM's broadcast signal. In addition to the interference, the station was affected by a strike, at about the same time. The striking FM air staff was temporarily replaced with announcers with little experience, making the station sound unpolished compared to its usual presentation. The station also began to face formidable competition after a relaunch of KSTP-FM "KS95," with a comparable live AC format. The station gravitated to a stricter playlist as the 1980s wore on. In 1983, Top 40 became a very popular format across the country. WLOL, which picked up the format by 1982, was one of the most successful stations in the market, and KDWB had moved from AM to the FM band. WCCO-FM also made the switch to Top 40 under Program Director John Long that year. Results were dismal, and both the format and Long lasted just a few months.
WLTE
The "Lite" format was introduced later in 1983, along with new call lettersWLTE. In addition to the soft adult contemporary format, the station switched to all-Christmas music from mid-November to midnight on Christmas, billing itself in that period as "The Official Christmas Music Station". Rival Kool 108, an oldies station, also programs nothing but Christmas music during this period. In 1998, the ownership of WLTE, along with sister station 830 WCCO, went to the Infinity Broadcasting Corporation, a subsidiary of CBS Radio. Until the early 2000s, the station had been known as "W-Lite" and "Lite Rock 103 FM," having rounded the frequency up to "103" since the WCCO-FM days. The frequency approximation worked in the days before digital tuners, and it eliminated confusion with KEEY, on 102.1. The station became "102.9 Lite FM" in the mid-2000s, as digital tuners became standard on most FM radios, displaying a station's exact dial position.
Buz'n @ 102.9
In December 2011, WLTE became the subject of format change rumors, amid falling ratings. On December 16, 2011, the station dismissed its entire on-air staff, effective December 23rd, while also dropping the use of the "Lite FM" moniker, and began promoting "Something Fresh Coming to the Twin Cities." CBS announced on December 19th that the station would switch to a country music format, to be known as "Buz'n 102.9," effective December 26th at 8:00 a.m.. However, 102.9 switched to country at 6:00 p.m. on December 25, about 14 hours earlier than originally planned. The final song on "Lite FM" was "Grandma Got Run Over by a Reindeer" by Elmo & Patsy, while the first song on "Buz'n" was "My Kinda Party" by Jason Aldean. On December 26, 2011, WLTE changed its call letters to KMNB to reflect the new branding. WLTE was the last of four CBS Radio stations to drop the AC format in 2011 after March's flip of WIAD in Washington, D.C. from AC to hot adult contemporary and WCFS-FM in Chicago on August 1 that year, when they went to all-news to simulcastAM 780WBBM. At the same time as the format flip, the former "Lite FM" AC format moved to co-owned KZJK 104.1-HD2, replacing smooth jazz. On February 2, 2017, CBS Radio announced it would merge with Entercom. The merger was approved on November 9, 2017, and was consummated on the 17th.
On November 23, 2018, KMNB began running promos pointing to a change on December 3 at 7 a.m., under the tagline 'the Buzz has worn off'. At that time, KMNB rebranded as “102.9 The Wolf”, keeping its country music format, but slightly tweaking it to include “yesterday’s country hits”.
KMNB broadcasts using the HD Radio format. It simulcasts the news/talk format of co-owned AM 830 WCCO on the station's HD2 sub-channel, and airs CBS Sports Radio on its HD3 sub-channel.
