KSJN

KSJN (99.5 FM) is a non-commercial, listener-supported, public radio station licensed to Minneapolis, Minnesota. It serves the Twin Cities region as the flagship of "YourClassical MPR", Minnesota Public Radio's classical music network. The studios are in the MPR Broadcast Center on Cedar Street in downtown Saint Paul.

KSJN is a Class C FM station. It has an effective radiated power (ERP) of 100,000 watts, the maximum for most FM stations. Its transmitter is on the KMSP Tower in Shoreview. Programming is also heard on several other stations and FM translators around Minnesota. KSJN broadcasts using HD Radio technology. Its HD2 subchannel carries "Classical 24," an all-classical network from American Public Media.

Classical and Easy Listening
On July 18, 1956, radio station WLOL (1330 AM) was granted a construction permit for a new FM radio station to be heard on 99.5 MHz. The station, WLOL-FM, began broadcasting in February 1957. It aired a classical music format. The station maintained this programming for its first 16 years of operation until the money-losing outlet switched to automated beautiful music in August 1973. The station donated its classical albums to KSJN 91.1 FM and KUOM 770 AM. The easy listening format proved to be popular as more people acquired FM receivers and offices played WLOL-FM for their employees and visitors. The station aired quarter-hour sweeps of soft instrumental music as well as Broadway and Hollywood show tunes.

Adult Contemporary
The competition in the easy listening format was evident in the Twin Cities. Other stations in the format included 102.1 KEEY-FM and WAYL AM 980 and FM 93.7 (now KKMS and KXXR). Midcontinent Broadcasting decided to sell WLOL-AM-FM to Bob Liggett of Liggett Broadcasting for $1.55 million in 1978. On August 20, Liggett, with a staff of nine disc jockeys, debuted a new soft adult contemporary station as Easy Rockin' FM 100 WLOL.

That brought WLOL-FM into competition with 94.5 KSTP-FM and 102.9 WCCO-FM (now KMNB). Ratings rose, but the station remained far off its direct competition.

Top 40/CHR era
On December 12, 1981, WLOL-FM changed formats again, this time to Top 40/CHR as 99½ WLOL. The ratings effect was quick to take hold; in the spring 1982 Arbitron survey, WLOL-FM more than doubled its performance and vaulted into third place in the Twin Cities, led by the revamped "Hines and Berglund" morning show hosted by John Hines and Bob Berglund.

Even while WLOL was surging, a sale was in the works. In 1982, an Indianapolis-based consortium headed by Jeff Smulyan acquired WLOL-FM for $6 million, a record price at the time for a Minnesota radio station. It was the first station purchase for Emmis Communications, which then bought two more stations the next year. The station peaked in the ratings in 1984 with a 9.9 share, closely behind second-place KSTP-FM and well ahead of direct format competitor KDWB. WLOL and KDWB would go on to have a bitter rivalry throughout the 1980s, with WLOL dominating the format in the Twin Cities for the next five years.

WLOL was noteworthy for its presentation, by combining typical Top 40 programming philosophies with a local touch. In addition, WLOL relied heavily on unique jingle packages, including the now iconic "Get Me Up!" jingle, which was written by Kyrl Henderson of the now defunct Reel Good Productions, and was distributed to stations across the country. Local artists such as Prince & The Revolution, Morris Day & The Time, Information Society, Alexander O'Neal and The Jets all received support from WLOL.

By the late 1980s, the tables were turned. After KDWB updated its on-air presentation in 1988, some listeners felt WLOL had grown stale, while KDWB suddenly became the hip new CHR station. KDWB and its morning show host, Steve Cochran, jumped ahead of a slumping WLOL and would, from that point on, be the dominant CHR station in the market. Playing catch-up, WLOL started tweaking the programming and air staff, shook up its longtime morning show. Finally, on May 11, 1990, it switched to a Rhythmic Contemporary format. Labeling itself as "Today's Best Music", 99.5 WLOL hired a new airstaff and rejuvenated itself in the minds of listeners, managing a ratings improvement.

St. John's University
Saint John's University in Collegeville, near St. Cloud, built and began operating the first station in the network, KSJR-FM (90.1), in January 1967. By 1968, it was obvious that there weren't enough listeners in the immediate St. Cloud area for the station to be viable. KSJR nearly tripled its power in hopes of reaching listeners in the Twin Cities, but even then it only provided grade B coverage of Minneapolis and minimal coverage of St. Paul. To solve this problem, the university signed on KSJN at 91.1 MHz, originally licensed to the northern Twin Cities suburb of New Brighton. It served as a full-time repeater of KSJR-FM.

By 1969, Saint John University's realized it was in over its head operating a two radio stations, so it turned over KSJR and KSJN to a nonprofit corporation, Saint John's University Broadcasting. This organization later changed its name to Minnesota Educational Radio, and finally Minnesota Public Radio.

In 1969 and 1970, MPR assisted in the formation of National Public Radio (NPR) and was a founding member of the organization. Four years later, in 1974, the network began live broadcasts of Garrison Keillor's A Prairie Home Companion. The show was among NPR's most popular offerings and it aired each Saturday from the Fitzgerald Theater in St. Paul.

MPR purchased WLOL (1330 AM) in 1980 and relaunched it as a dedicated news and talk service centered around NPR programming. The call letters were switched to KSJN. This station was renamed KNOW in 1989. It has since returned to the WLOL call sign and it broadcasts Catholic religious programming.

KSJN and KNOW relocation
In 1989, Emmis CEO Jeff Smulyan bought the Seattle Mariners baseball team. As early as September 1989, rumors were swirling that WLOL might be up for sale to raise funds for the acquisition. It later emerged that Emmis had indeed placed the station up for sale.

On December 26, 1990—-realizing an ambition held for over a decade—-Minnesota Public Radio announced the purchase of the WLOL facility. The price tag was $12 million. For Emmis, it was a discount on the original asking price of $20 million, which a slowing economy had put out of reach. The purchase would give MPR two FM frequencies in the Twin Cities. MPR had been operating both AM and FM stations since it had bought 1330 kHz—-the former WLOL AM-—in 1981. It would sell the AM station, by that time known as KNOW, to raise some of the funds for the FM purchase.

MPR announced that it would move its classical programming to the 99.5 frequency. That would give classical music fans an all-classical outlet, while those interested in news and information would have their own full time NPR station. The 91.1 frequency would become the new home of KNOW-FM, which no longer spent part of each day playing music.

Emmis took some steps toward enabling another commercial radio owner to pick up WLOL, going as far as to provide such a blueprint to other FM stations in the Twin Cities market. But MPR fans wanted a full power FM station for news and talk programs. AM 1330 had been challenged by a poor signal in the western suburbs that were home to many MPR members, as well as in office buildings.

WLOL final broadcast
Pop music fans in the Twin Cities were upset as WLOL slowly counted down to its last day, February 26, 1991. WLOL's final broadcast culminated with a day-long farewell, playing music and jingles from the station's nearly 10 year-long Top 40/CHR era. Current and former airstaff offered farewell messages, and advertisements from KQRS-FM, KEEY-FM (where morning host John Hines later landed) and even KDWB redirected listeners to their stations. At 6:30 p.m., WLOL left the air with a half-hour montage of clips from songs played by the station during the Top 40/CHR era, followed by a sign-off announcement from Hines and "Miss You Much" by Janet Jackson.

At 7 p.m., after about a half hour of dead air, WLOL started playing music without live DJs for about an hour. Liners played in between songs with KDWB wishing WLOL "happy trails" and redirecting listeners to their station. WLOL officially signed off with 1999 by Minneapolis native Prince fading out. WLOL ended 34 years of serving the Twin Cities.

Debut of Classical KSJN-FM
The next morning, 99.5 became the new home of KSJN. It told listeners it would play classical music 24 hours a day. The KNOW call sign, along with all NPR news and talk programming, moved to 91.1. On March 11, the KSJN call letters officially moved to 99.5 FM. Meanwhile, the KNOW-FM call sign was instituted on 91.1 FM.

The historic WLOL call letters were soon claimed by KXLV, a station located north of the Twin Cities in Cambridge at 105.3 FM. When the station was purchased and turned into WREV, the call sign was parked on KZTG (1470 AM). They were then used on 100.3 MHz from 1999 to 2003 and were restored to the 1330 AM frequency in 2005.

In 2005, KSJN was the first MPR station to broadcast regularly with the digital HD Radio system. KSJN currently features the Classical 24 feed on its HD2 subchannel.
