WUCS (97.9 MHz, "97-9 ESPN") is a commercial FM sports formatted radio station licensed to Windsor Locks, Connecticut. It is owned by iHeartMedia, Inc. and serves as the Hartford media market's ESPN Radio network affiliate. WUCS acts as the technical flagship station for the network because its signal covers Bristol, Connecticut, home of ESPN's headquarters. The station first signed on in July 1990 as WPKX, a country music station targeting Springfield, Massachusetts. It was originally licensed to Enfield, Connecticut but was able to move to Windsor Locks through an agreement with WMAS-FM which was formerly licensed to Springfield. WUCS's studios are at 10 Columbus Boulevard, in Hartford.
