 On January 22, 1988 the sixty-four-year-old WGBB call letters were retired and 1240 took the identity of its FM sister station becoming WBAB and began simulcasting WBAB-FM most of the time.Also in 1988 night-time power was increased to 1,000 watts from 250 watts as was the case for all class IV local channel stations in the U.S. on 1240 and other local frequencies including 1230, 1340, 1400, 1450, and 1490.When the simulcast with WBAB-FM ended 1240 began airing a news-talk format and on April 15, 1991 returned to the original WGBB call letters.
