XHRRT-FM (branded as Heraldo Radio) is a Mexican Spanish-language radio station that serves the Tampico, Tamaulipas market area.
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.
In 2011, XERRT was authorized to move to FM as XHRRT-FM on 92.5 MHz.
On August 1, 2019, XHRRT changed again from One FM to the news and talk programming of El Heraldo Radio relaying XHDL-FM from Mexico City.
