On September 3, 1982, the Secretary of Communications and Transport published an accord in the Diario Oficial de la Federación making available for commercial use XHCAN-FM on 107.5 MHz in Cancún, Quintana Roo.
Out of several bidders for the frequency, in November, Roberto Martínez Vara y López Portillo was selected to proceed to obtain a concession for the station.
[3] Five concessionaires objected after the awarding of the concession to Vara y López Portillo, with four of them also expressing concern in a letter to the SCT in 1995.
In 1997, two court rulings in Mexico City and Quintana Roo offered Vara y López Portillo an amparo to continue with the process of applying for the concession.
In an administrative resolution dated May 12, 1997, the SCT denied the concession, on the grounds that the applicant "did not guarantee the social interest" by proceeding to install and operate the radio station.
