WOSF "Old School 105.3" is an Urban Oldies station in Gaffney, South Carolina; serving the Charlotte, North Carolina market. WOSF is the Charlotte affiliate of the Tom Joyner Morning Show.  Owned by Gaffney Broadcasting, LLC, the station's studios are located in South Charlotte near Carowinds, and the transmitter site is located in Dallas, North Carolina.
105.3 signed on as WAGY-FM in 1959, as the FM sister to WAGY (AM 1320) 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" (heard at 6:35am, 12:15pm, & 5:15pm Monday to Saturday) 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 remains in the community. Shortly after midnight on April 21, 2007, WAGI ceased operations and then began broadcasting a Regional Mexican format as WNOW-FM, "105.3 Poder FM", under a Local Marketing Agreement. It also began 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. Cherokee County coroner Dennis Fowler (a well-known WAGI personality) 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 (the same location of 101.9 WBAV-FM, with similar coverage). However, this was changed; the station moved to rented space on WBTV's tower in Dallas in June 2009. The new transmitter made WNOW-FM the only commercial station licensed to the South Carolina side of the market that covers Charlotte to any significant extent.
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 has acquired WNOW-FM from Gaffney and will start programming the station via a LMA 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.
