KQQZ was a commercial AM radio station that was licensed to serve Fairview Heights, Illinois, United States, on 1190 kHz, and broadcast from 1968 to 2020. The transmitter site was located in the town of Pontoon Beach, Illinois.

KQQZ first broadcast in 1968 as KHAD, a station licensed to De Soto, Missouri. For its first 30 years, KHAD primarily broadcast country music and talk shows. A potential sale to the Rev. Larry Rice was terminated in 2000 after a fire destroyed KHAD's studios and transmitter. Eventually, the Radio Free Texas Trust bought KHAD, changed its call sign to KRFT, and operated KRFT as a sports talk station. The sports format continued until 2010, when financial losses and the Great Recession forced the owners to sell the station.

The station's license, and the licenses of three other co-owned stations in Greater St. Louis, were revoked by the Federal Communications Commission (FCC) on March 20, 2020, after it was revealed that the principal ownership—Entertainment Media Trust—was set up as a shell company for a convicted felon, Robert S. Romanik, who operated the stations under the "Insane Broadcasting Company" name. Despite the cancellation, Romanik continued to broadcast without a valid license on the frequency until April 12, 2020. While having carried a classic country format to the end of its existence, KQQZ also aired a controversial daily talk radio show hosted by Romanik, the content of which led to additional license challenges for having potentially violated federal law against broadcasting obscenities.

This station began operations as KHAD on November 1, 1968, originally licensed to serve De Soto, Missouri. KHAD was a 1,000-watt daytime-only station owned by the DeSoto Broadcasting Company, a six-person partnership whose principals included Pinkney Cole. In 1969, KHAD broadcast 20 hours of country music a week. By 1970, KHAD affiliated with the Mutual Broadcasting System and played 70 hours of country music a week. By 1974, KHAD added middle of the road music and talk shows to its lineup.

In 1976, KHAD had news and talk shows in addition to country music. On December 13, 1977, KHAD strengthened its power from 1,000 to 5,000 watts and remained a daytime-only station.

KHAD was sold in 1981 to the Jefferson County Broadcasting Company—a joint operation between Pinkney and Judy Cole and Erich and Arlene Schafermeyer. The company maintained the previous Mutual Broadcasting System affiliation, with talk shows and middle of the road music through the end of the decade. The station was sold again in 1990 to Jefferson Communications. As of 1992, KHAD had a talk and country music format, with 12 hours of gospel and three hours of bluegrass weekly. In 1993, KHAD was sold to Big River Broadcasting, and to Schafermeyer Broadcasting in 1996 after Erich and Arlene Schafermeyer purchased the remaining shares owned by the Coles; son Kim Schafermeyer assumed the role of principal owner and handled the day-to-day operations of both KHAD and FM adjunct KDJR, which took to the air in 1990. The 1997 Broadcasting Yearbook listed KHAD as a "traditional country" music station.

Following months of negotiations in the fall of 1999, Schafermeyer Broadcasting reached an agreement to sell KHAD to the Rev. Larry Rice, founder and then-owner of St. Louis television station KNLC, for $225,000. Rice had planned to change KHAD's call sign to KCBW and have the station be operated in tandem with a free store in De Soto that his New Life Evangelistic Center ministry was planning to open. On January 27, 2000, the day before the sale was to have closed, an early-morning fire destroyed the studios and transmitter facilities, resulting in the deal being postponed, then called off entirely. Arson was suspected as a likely cause for the fire by area law enforcement, but no arrests were made.

Shortly after the fire, the general manager for both stations filed a complaint with the Jefferson County, Missouri, prosecuting attorney after her last paycheck had bounced; Rice had also been approached by people in phone calls and letters regarding debts owned by the stations. An attorney representing Erich and Arlene Schafermeyer admitted to the debts, but did not specify the exact amounts owed. Kim Schafermeyer had been estranged from his parents since the preceding June over real estate matters; consequently, neither parent had any involvement—nor were informed about—the sales for either station, and both considered the deals "fishy" and "messed-up".
