sold to Entercom (now Audacy) and become a repeater of WILK, existing mainly to improve its signal in Scranton. While WILK's daytime signal easily covers most of Scranton, the northern portion of the city only gets a grade B signal. At night, WILK must power down to 1,000 watts, leaving most of Scranton with only a grade B signal. In 2005, Entercom flipped a station in the Madison, Wisconsin, area to adult hits; the WBZU call letters were parked in Scranton, ending 80 years as WGBI. In 2007, the station moved its transmitter to the tower location atop the Times Building at 149 Penn Avenue in downtown Scranton also being used by WEJL's transmitter. The full-time switch over to the new transmitter facility and tower location happened on August 2, 2007. This tower sharing arrangement repeats an arrangement the stations shared over 60 years ago in their early history. The efficiency of the new transmitter tower location also caused WBZU to slightly reduce its power to keep within Federal Communications Commission rules on signal strength and coverage. On February 26, 2020, the WAAF call letters were transferred to WBZU from 107.3 FM in Boston, which had held the call sign since 1968. When Entercom announced they would sell WAAF to the Educational Media Foundation, the call letters were "parked" in Scranton, preventing a rival Boston station from using the call sign.
