105.3 signed on as WAGY-FM in 1959, as the FM sister to WAGY in Forest City, North Carolina. The station at the time was partially owned by Raymond Parker. WAGY-FM was sold entirely to Parker, who with his wife, Bright G. Parker, formed Gaffney Broadcasting in 1971 and moved WAGY-FM to Gaffney, pairing it with their AM WEAC, and changing the call letters to WAGI-FM, increasing the power to 100 kW in the process. WAGI's longtime slogan was "The Upstate Power Station" and was nicknamed for many years by the locals as "Waggie". The station had featured a mixture of Country and Southern Gospel music for many years. WAGI broadcast local as well as national news from the NBC Radio Network, as well as local sporting events from Gaffney High School, namely Gaffney Indians football. Also, the station had a morning show called "Carolina in the Morning" and a popular show called "Swap & Shop" where listeners could call in to buy, sell, or trade items. After Raymond Parker, the owner of WAGI, died in 2005, his will stipulated that the station be sold upon the death of his wife, Bright G. Parker. Parker's will stated that the station was to remain in Gaffney, though this was ignored by the executors of his will. Upon her death in 2006, the station was sold to Davidson Media under a lease/purchase agreement. In late April 2007, it was announced that the station was sold to local interests in order to ensure that the station remained in the community. Shortly after midnight on April 21, 2007, WAGI ceased operations, moved its studios to Charlotte, North Carolina, then began broadcasting a Regional Mexican format as WNOW-FM, "105.3 Poder FM", under a Local Marketing Agreement targeting the Charlotte market. Listeners were told that WAGI's former programming could be found on the AM station, which had a limited signal range and broadcast only during the day. Gaffney Indian Football moved to 103.3 WOLT, broadcasting from Greer. Fabian Fuentes remained the announcer for the games. During the games, former commercials featured on WAGI could be heard. These commercials were primarily for the Gaffney area. A construction permit was granted to move 105.3 in order to move its transmitter location to Crowder's Mountain in North Carolina, halfway between Kings Mountain and Gastonia. However, this was changed; the station moved to rented space on WBTV's tower in Dallas in June 2009. Even with a power decrease to 51 kW, it still gave WNOW-FM a coverage area comparable to the major Charlotte stations. Starting in 2011, WNOW-FM aired SportsCenter from ESPN Deportes and hourly sports updates. During the 2011-12 season, WNOW-FM aired North Carolina Tar Heels men's basketball games, as well as any football games kicking off after 5 pm. This is because the Tar Heel Sports Network's main Charlotte station, WFNZ, had a weak signal at night. This ended after only one season after the Tar Heels signed a new deal with WBT. On August 16, 2012, Radio One announced that it had acquired WNOW-FM from Gaffney Broadcasting. Pending the close of the purchase, Radio One took over the station's programming via a local marketing agreement on August 27, 2012, ending Davidson's involvement with the station. On August 27, 2012, at 5:00 pm, WNOW-FM flipped to Urban Oldies, branded as "Old School 105.3". Core artists include Luther Vandross, the Isley Brothers, Michael Jackson, Earth, Wind & Fire, and Anita Baker. Radio One regional vice president Gary Weiss said the format had done well on KSOC in the Dallas market. The first song on "Old School" was "Fantastic Voyage" by Lakeside. The station changed its call letters to WOSF on November 8, 2012, after the WNOW-FM call sign moved to the former WXRK in New York City. WOSF operated two translators to improve its coverage--in Charlotte at 96.5 FM, and Dallas at 98.3 FM. In 2014, it sold the translators to Radio Training Network, who converted them into repeaters for its "His Radio" contemporary Christian network. The translators are now part of the license of His Radio flagship WLFJ-FM in Greenville, South Carolina. However, they identified as "His Radio 96.5 and 98.3," and air separate commercials as well. Due to the translators' limited range, the translators' programming was simulcast on WOSF's second HD Radio channel until 2017, when the simulcast moved to a new second channel on WHQC. On August 1, 2018, WOSF shifted its format from urban oldies to urban adult contemporary, branded as "105.3, Old School + R&B". The change means instead of songs from the 1970s through the 1990s, WOSF now plays songs from the 1980s to the present. Rickey Smiley, Olympia D and D.L. Hughley remain as personalities.
