History
XHMAXX received its first concession on June 8, 1993, as XHSTX-FM, owned by Teleradio de Teziutlán, S.A. de C.V. The station was sold to Radio XHMAXX, S.A. de C.V., in 1998; the station may have signed on under the XHMAXX call sign, and it certainly did not have them by 1999 when the XHSTX call sign was reassigned in Santiago Tuxtla, Veracruz.References
