WQSN is an Alternative Rock formatted broadcast radio station licensed to Norton, Virginia, serving Big Stone Gap, Pennington Gap, and Clintwood in Virginia, Whitesburg, Cumberland, and Jenkins in Kentucky, and Kingsport in Tennessee.

WNVA was first owned and operated by the Blan Fox Radio Company and was affiliated with Mutual Broadcasting System, but has always remained under the same ownership since its conception in 1946.

On December 28, 2008, WNVA-FM changed its format from the Jones Radio Network's Hot AC to the New Dial Global's Classic Hit Country.

Radio-Wise Inc. sold WNVA-FM and sister station WNVA to Bristol Broadcasting Company for $35,000, enough to settle property tax debts and outstanding FCC fines; the sale closed on January 16, 2015.

The station changed its call sign to WSMQ on August 28, 2017, and to WQSN on September 4, 2017.
