WKQX (101.1 FM) – branded as 101 WKQX – is a radio station serving the Chicago metropolitan area. The station is owned by Cumulus Media. A former NBC Radio owned-and-operated station, WKQX is best known for carrying a long-running alternative rock format from 1992 until 2011 as "Q101." WKQX aired an alternative rock music format that originated on the former WKQX-LP (87.7 FM, or LPTV channel 6) from 2012 until 2014.
From the station's 1948 launch to 2016, WKQX's studios were located in the Merchandise Mart. Co-located with onetime sister stations WMAQ (670 AM) and WMAQ-TV from 1948 to 1989 and WLUP (97.9 FM) from 2001 onwards, the station relocated to the NBC Tower, the current home of WMAQ-TV, on August 4, 2016. Its transmitter is located atop the John Hancock Center.
Besides a standard analog transmission, WKQX broadcasts over two HD Radio channels, and is available online. WKQX's HD1 channel is a direct simulcast of the analog station's programming feed, while WKQX HD2 airs a classic rock format branded as "The Loop" that was previously heard on the former WLUP (97.9 FM), now WCKL-FM.
