XEYC received its first concession on February 25, 1949. It operated on 1460 kHz with 1.000 watts and was owned by and named for Ysela Fernandez Caballero de Yañez. The station was known as "Radio Ysela". Fernandez Caballero died on June 21, 1972.
XEYC was sold to XEYC, S.A., in 1980. In 1998, the concession was sold directly to Formula in the person of Rogerio Azcarraga Madero. The 1999 concession listed XEYC on 1030 kHz with 5.000 watts day and 500 watts night. The 2009 concession lists 1460 kHz as the frequency, but promotional materials mentioned 1030 AM until XEYC returned to 1460 on May 27, 2018.
