The concession for 106.5 MHz in Mexico City was awarded in 1964 to México Radio , S.A. , for '' ' XHMR-FM ' '' . Not long after , the station 's callsign was changed to '' ' XHABC-FM ' '' , reflecting the station 's then-common ownership with XEABC-AM 760 . The station was sold to Fórmula Melódica in 1977 and the callsign changed to the current '' ' XHDFM-FM ' '' . Fórmula Melódica , owned by the Guadalajara-based Ondas de Alegría group , broadcast romantic and ranchera music in Spanish until 1981 , when it became " La Nueva Onda " and changed its format to ballad music . The station moved studios in 1985 after its previous facilities were heavily damaged by the 1985 Mexico City earthquake
