Licensed to Ponce, Puerto Rico, the station serves the entirety of the island with the aid of a booster at Caguas and a translator covering Mayagüez.

The Catholic University of Puerto Rico entered into broadcasting when it built WEUC,[5] a 1,000-watt AM radio station operating at 1420 kHz, in 1958.

[9] On May 17, 1979, the Catholic University of Puerto Rico applied to the Federal Communications Commission to build and launch a noncommercial FM station on 88.9 MHz.

[10] The university sold the AM station in 2000 to El Mundo Broadcasting Corporation, owners of WKAQ-AM-WKAQ-FM in San Juan and WUKQ-FM in Mayagüez, for $1.45 million; the sale resulted in the AM frequency becoming a simulcaster of WKAQ.

[12] In 2014, the station's main studio was named for Luis Varela (1938[13] - 23 June 2020[14]), whose sports program Trinchera Deportiva aired from WEUC/WPUC since 1961.
