XHHLL-FM is a radio station on 97.1 FM in Salina Cruz, Oaxaca, Mexico carrying the Los 40 format.
The concession for XEUC-AM was awarded to Eduardo Martínez Celis in 1962. In the 1980s, Humberto Alejandro López Lena Robles bought the station; he changed its calls to XEHLL-AM "Radio Mar" in 1991 and moved it from Tehuantepec to Salina Cruz. XEHLL became an AM-FM combo with the award of XHHLL-FM in 1994 and began calling itself "Estéreo Mar". The station became FM-only when it surrendered the AM concession in a letter dated June 30, 2023.[1]
