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".

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.

[5][8] 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.

[10] Even with a power decrease to 51 kW, it still gave WNOW-FM a coverage area comparable to the major Charlotte stations.

This is because the Tar Heel Sports Network's main Charlotte station, WFNZ, had a weak signal at night.

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 translators are now part of the license of His Radio flagship WLFJ-FM in Greenville, South Carolina.

[15] WOSF carries a hip hop format on its second HD Radio subchannel; it is branded as "102.5 The Block" in reference to its carriage on 200-watt FM translator W273DA at 102.5 MHz.
