XHSUR-FM was a radio station on 93.5 FM in Chilapa de Álvarez, Guerrero, Mexico.
It is owned by Cadena Radial del Sur, S.A. de C.V., and is known as La Más Bonita.
XECLA-AM 770 received its concession on August 2, 1989, signing on March 18, 1990.
In 1997, it was sold to Cadena Radial del Sur, S.A. de C.V. and promptly changed calls to reflect its new ownership.
On August 19, 2021, Cadena Radial del Sur surrendered the concession and informed the Federal Telecommunications Institute that it would shutter the station on August 31, citing 3.4 million pesos in debts owed to utilities, back taxes, and other unpaid obligations, as well as the loss of population and businesses due to violence and COVID-19 and a lack of advertisers.
