their stations. At 6:30 p.m., WLOL signed off 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 (with more liners in between from KDWB wishing WLOL "happy trails" and redirecting listeners to their station), after which it officially signed off with 1999 by Minneapolis native Prince fading out as WLOL ended after 34 years of serving the Twin Cities. The next morning, 99.5 became the new home of KSJN, which began playing classical music 24 hours a day. The KNOW call sign, along with all NPR news and talk programming, moved to 91.1. (The KSJN call letters officially moved to 99.5 (along with the KNOW-FM calls being instituted on 91.1) on March 11.) 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.
