[4] In 1972, Gerald Green, who also served as station president and general manager, was embroiled in a controversy with the Federal Communications Commission (FCC) over whether $19,000 he paid to an ABC network representative was a bribe.

[4] In 1976, Dubuque Communications Corporation, which had become insolvent, sold the dormant station for $30,000 to Lloyd Hearing Aid Corp[7] of Rockford, Illinois.

In 1981, KDUB won a decision in which the Dubuque cable company was required to black out KCRG when the same shows were shown at the same time on both stations.

[14] In 1995, KDUB entered into a management agreement with Second Generation of Iowa, which was in the process of acquiring Cedar Rapids Fox affiliate KOCR-TV (channel 28).

Prior to this, KOCR served as the network's over-the air affiliate for most of the southern portion of the market while Foxnet (which had launched in 1991) served as the network's cable-only affiliate for the remainder of the market, including the cities of Waterloo and Dubuque (it was carried on cable channel 13 in Dubuque); between October 7, 1994, and August 12, 1995, Foxnet was carried on all cable systems in most of Eastern Iowa as KOCR was off the air during that time due to financial issues.

[17][18] The first season of the NFL on Fox was carried by Cedar Rapids CBS affiliate KGAN, which had a greater coverage area than KOCR; Foxnet was blacked out during the games.

[19] KFXB's eight news staffers were laid off in the transition, with its former reporters telling the Telegraph Herald that the first indication of the planned change was a promo aired during Fox's baseball coverage.
