The station first signed on in July 1990[1] as WPKX, a country music station licensed to Enfield, Connecticut. The station originally targeted Springfield, Massachusetts, even though Enfield is part of the Hartford market. However, Enfield is on the Connecticut-Massachusetts state line. It was owned by SFX Broadcasting in the late 1990s, then Capstar. AMFM owned it briefly before being acquired by Clear Channel Communications (now iHeartMedia) in 2000.
In March 2010, Clear Channel Communications filed an application with the FCC to move the WPKX transmitter from Provin Mountain in Feeding Hills, Massachusetts to the top of City Place in Downtown Hartford, in a bid to move the station from the Springfield Arbitron market to the larger and more lucrative Hartford Arbitron market.[3] In January 2011, the move was refiled with a city of license change to Windsor Locks; this followed an agreement with WMAS-FM, which agreed to change its city of license from Springfield to Enfield as part of a deal involving a Clear Channel-owned generator in Albuquerque, New Mexico.[4] The previous country format moved to WRNX (100.9 FM).
On January 27, 2012, at 6 a.m., the station switched to a simulcast of ESPN Radio affiliate WPOP (1410 AM).[5] The call sign was changed to WUCS on February 7, 2012.[6] WPOP switched to Fox Sports Radio in March 2012, with ESPN Radio remaining on WUCS.
