On October 13, 1924, the station first signed on with the call sign WJJD. The station was owned by the Loyal Order of Moose and was located in Mooseheart, Illinois. In January 1925, its frequency was changed to 990 kHz and in December 1925 it was changed to 810 kHz. By 1926, the station's power had been increased to 1,000 watts. and 40s. In 1933, the station was sold to a firm headed by Ralph Atlass, and its studios were moved to the Trustees System Service Building in Chicago. Lew Fonseca and Charlie Grimm broadcast Chicago Cubs baseball games on WJJD during the 1939 and 1940 seasons. WJJD won the exclusive rights to broadcast Cubs games locally in 1944, though 560 WIND won exclusive rights to broadcast the following season. Ed Short was the station's director of sports publicity and promotion from 1946 until 1950, when he became the Chicago White Sox press and promotion director. In 1944, the station was sold to Field Enterprises for approximately $750,000. In 1947, the station's power was increased to 50,000 watts, although it could only broadcast during the daytime. Al Benson was a R&B disc jockey on WJJD in the late 1940s. In 1953, Plough Broadcasting purchased WJJD for $900,000. Plough Broadcasting was a subsidiary of the large pharmaceutical company Schering Plough. WJJD featured both pop and country music programs in the 1950s, in an era where country and western music was not common on radio stations in Northern U. S. cities. In June 1956, WJJD left country music for several years, flipping to a Top 40 format. But with tough competition from 890 WLS in the early 1960s, WJJD shifted to a pop standard format. The station's programming was simulcast on 104.3 WJJD FM, with the FM station continuing WJJD's country programming after sunset. In April 1982, the station began 24 hour operations, running 2,500 watts at night, with plans to increase its nighttime power to 10,000 watts in July. However, its nighttime power was reduced to 5,000 watts later that decade. In February 1982, WJJD adopted an adult standards format, and carried programming from the syndicated "Music of Your Life" network. Its audience share tripled following the format change. The station was branded "Music of the Stars" and featured artists such as Frank Sinatra, the Count Basie Orchestra, Tony Bennett, Patti Page, the McGuire Sisters, Glenn Miller, Tommy Dorsey, Nat King Cole, and Barbra Streisand. Hubbard and Hellyer both left WJJD in 1983, with Hubbard joining AM 820 WAIT. In 1984, WJJD and WJEZ were sold to Infinity Broadcasting for $13.5 million. Clark Weber joined WJJD in 1985, hosting a talk show weekday mornings, while adult standards continued to air in the remainder of the schedule. In April 1993, the station began airing G. Gordon Liddy's syndicated talk show middays. In November 1994, WJJD dropped adult standards music altogether for a full time talk format. Hosts included Ed Vrdolyak, Ty Wansley, G. Gordon Liddy, David Brenner, the Don and Mike Show, Tom Leykis and Jim Bohannon. Ed Vrdolyak and Ty Wansley were moved from mornings, and replaced Don and Mike in the afternoon. In 1996, Infinity Broadcasting was purchased by the parent company of CBS. That meant WJJD was now sister stations with WBBM and WBBM FM. On February 3, 1997, the station began simulcasting the oldies programming of 104.3 WJMK.

In 1997, CBS sold its Chicago sports radio station 820 WSCR. CBS wanted to put its sports programming on a more powerful station, so WSCR's sports shows were moved to AM 1160 on April 7, 1997. The station was branded The Score. Hosts on The Score during this period included Norm Van Lier, Doug Buffone, Terry Boers, Dan Bernstein, Mike North, Dan McNeil, and Dan Jiggetts. Two weeks later, the WSCR call sign officially moved to AM 670, retiring the long standing WMAQ call letters on 670 in the process. On August 15, 2000, 1160's call sign was changed to WXRT, and the station began simulcasting the adult album alternative programming of 93.1 WXRT FM. In February 2001, Salem moved the Christian talk programming of WYLL 106.7 FM to 1160 AM, along with the WYLL call letters. FM 106.7 switched to a Christian contemporary music format the following month. In addition to the primarily national Christian talk and teaching programming heard on the station, Sandy Rios hosted a local talk show weekday afternoons on WYLL from 1994 to 2001 and again from 2007 to 2010, when she moved to Washington, D. C.

On April 7, 2005, WYLL's nighttime power was increased to 50,000 watts. The higher power required a six tower directional array, with the towers used for daytime broadcasts about 30 miles away from the towers used for nighttime operation.
