WAAF (AM)

WAAF (910 kHz) is a commercial AM radio station licensed to Scranton, Pennsylvania. Owned by Audacy, Inc., WAAF airs a talk radio format. It is powered at 900 watts by day and 440 watts at night, using a non-directional antenna at all times. The transmitter is at the corner of Penn Avenue and Spruce Street, on the Scranton Times Building. In addition to a standard analog transmission, WAAF's programming is available online via Audacy.
WAAF is one of four simulcast radio stations in Northeast Pennsylvania that call themselves "WILK Newsradio", along with 103.1 WILK-FM in Avoca, 1300 WODS in West Hazleton and 980 WILK in Wilkes-Barre. Studios and offices are on Route 315 in Pittston. 
"WILK Newsradio" has a weekday schedule with mostly local hosts, except for the early afternoon when the station carries Rush Limbaugh. At night, the stations air nationally syndicated shows including Dave Ramsey, Coast to Coast AM with George Noory and America in The Morning. Weekends feature shows on money, health, technology and science. Weekend syndicated hosts include Kim Komando, Clark Howard, Dr. Michio Kaku and "Somewhere in Time" with Art Bell. Some hours on weekends are paid brokered programming. Most hours begin with world and national news from ABC News Radio.
The stations also carries play-by-play sports including Penn State Nittany Lions football and basketball, as well as Wilkes-Barre/Scranton Penguins minor league hockey.
History.
The station signed on the frequency of 1250 kHz in 1925, as WGBI. It was owned by Frank S. Megargee. In 1927, the station moved to 1300 kHz, which it time shared with Scranton's other radio station, WQAN (now WEJL). The two stations, which were time sharing a single frequency, moved to 880 kHz in 1931, and then again to 910 kHz by 1941 (the later move, forced by a nationwide frequency reassignment, took place in 1941). WGBI remained at 910 kHz when WQAN moved on to its own broadcast tower and new frequency of 630 kHz in 1948. This meant that WGBI had full-time use of the 910 kHz frequency, where it remains to this day. WGBI was a CBS Radio network affiliate by the 1940s.
The Megargee family's company, Scranton Broadcasters, put an FM station on the air (now WGGY) and Northeast Pennsylvania's second television station (now WYOU). The Megargees held on to the radio stations well into the 1990s. By the turn of the century, WGBI had been 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 sign was switched from 107.3 FM in Westborough/Boston, Massachusetts (now WKVB), when the station was announced to be sold. This allows the WAAF call letters to be parked in Scranton, preventing a rival Boston station from using that call sign.
