It also operates four four 10-watt FM stations in Yucatán . The 21 main stations transmit for an average of 12 hours a day , during daylight hours , covering 928 municipalities with high levels of indigenous inhabitants . The stations ' potential audience comprises 5 million speakers of indigenous languages and more than 22 million Spanish speakers . They all broadcast an array of programming in both Spanish and the particular native languages spoken in the coverage area . Four stations are AM-FM migrants : XHCARH , XHPET , XHTUMI , XHNKA . XHCARH and XHPET are required to maintain their AM frequencies because they are the only radio service for certain communities in its AM coverage area . The second and third stations reacquired their AM frequencies under new callsigns . In 2016 and 2017 , the CDI applied for and received FM radio stations that provide simulcast service for XETLA ( XHPBSD-FM 95.9 ) , XEVFS ( XHSEB-FM 91.7 ) , XEGLO ( XHGJO-FM 88.3 ) , and XEQIN ( XHSQB-FM 95.1 ) .
