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]
