RADIO MUNDO 89.3 (Mérida)

Radio Mundo 89.3 (XHMIA-FM) is a radio station on 89.3 FM in Mérida, Yucatán, Mexico, carrying a news and adult contemporary format. It is owned by Multimedia del Sureste, S.A. de C.V.

The station received its concession on September 24, 1992 as XHTVY-FM, promptly changing to its current callsign XHMIA-FM before signing on in 1996. It was then known as "Mia 89.3" and was owned by Arturo Iglesias y Villalobos, with José Laris Iturbide of Cadena RASA assisting in operations. Though the station was not part of RASA's Yucatán cluster and ran from separate studios, Laris Iturbide became the 50-percent owner of its new concessionaire in 2010. The station changed names to N-ergy 89.3 in the early 2000s and to Ultra 89.3 in 2008.

It dropped the Ultra name in 2011 and relaunched the next year as Sona 89.3 with a pop format. On September 1, 2019, it relaunched as Wow 89.3, keeping the pop format. In 2022, the station became Radio Mundo and shifted toward an adult contemporary format.
