The permit was issued to the Centro de Promoción Social y Cultural, A.C. in 1965, and the station signed on with a power of 250 watts.
By the late 1970s, the SCT was threatening to revoke XEYT's permit, which forced the station to seek support for its modernization.
In 1980, Radio Teocelo signed an agreement with Fomento Cultural y Educativo, owners of what was then known as XEJN-OC, and underwent a series of significant upgrades in the decade that followed.
In 1998, Asociación Veracruzana de Comunicadores Populares, A.C. (Avercop) was formed to manage the station.
The station also has offspring projects in television (Teocelo Te Ve) and a newspaper, Alta Voz.
