XHCA originated as a concept in 1986 to provide information and entertainment to the workers in the three shifts at the Cruz Azul cement plant in Lagunas.
The station is one of several set up by employers in small Mexican towns in the 1970s and 1980s: XHSCO-FM in Salina Cruz was originally owned by PEMEX, while XELAC-AM in Lázaro Cárdenas, Michoacán was created with the construction of the SICARTSA iron and steel mill.
Originally known as Estéreo Amistad, XHCA was run by four members of the cooperative, while the station's air staff also were company employees.

This gives the station a much larger coverage area than Lagunas, reaching as far south as Salina Cruz and including small portions of Veracruz and Chiapas.
