XED-AM (1050 kHz) is a commercial AM radio station in Mexicali, Baja California, also heard in the Yuma, Arizona and El Centro, California radio markets. It is owned by Radiorama and simulcasts its XHMUG-FM 96.9 "La Poderosa". Prior to being a simulcast of XHMUG, it was known as "La Gran D" or "The Big D". Because AM 1050 is a clear channel frequency reserved for XEG in Monterrey, Nuevo León, XED must greatly reduce power at night to avoid interference; it was a daytime-only radio station for nearly seven decades.
