XHPTUX-FM is a radio station on 101.3 FM in San Juan Bautista Tuxtepec, Oaxaca, Mexico. It is owned by Grupo Rojaz and carries the Exa FM national format from MVS Radio.
XHPTUX was awarded in the IFT-4 radio auction of 2017. The initial winning bidder, Tecnoradio, paid 2.35 million pesos for the frequency, but was later disqualified nationwide. Radio Casandoo's third-place bid of 2.265 million pesos was accepted in Tecnoradio's station[2] and the station signed on June 3, 2019, marking the beginning of serious commercial competition in Tuxtepec, which had previously been monopolized by the ORP stations (XHUH-FM and XHXP-FM).[3]
