XHRRT-FM (branded as El Heraldo Radio) is a Mexican Spanish-language radio station that serves the Tampico, Tamaulipas market area.
XERRT-AM received its concession on April 16, 1961. It broadcast from Ciudad Madero on 1190 kHz as a 500-watt daytimer. By the end of the 1960s, XERRT had moved to 1270 kHz and began broadcasting with 250 watts during the day and 200 at night. A 1990s power hike brought XERRT to 2,000 watts during the day and 500 at night.
