XHDB-FM is a radio station on 101.5 FM in Tonalá, Chiapas, Mexico. The station is owned by Radio Núcleo and known as Extremo.
XHDB-FM began as XEDB-AM 1290, with a concession awarded on July 10, 1968, which is when it first went on the air. It was owned by Alberto Muñoa Gómez. In 1988, ownership passed to a corporation, and in the early 2000s, XEDB moved from 1290 to 860 in order to increase daytime power from 1,000 watts to 5,000.
XEDB was cleared for AM-FM migration in November 2010.
