XEJP-AM (1150 kHz) is a commercial radio station in Mexico City. It is owned by Grupo Acustik and it airs a Regional Mexican radio format.
By day, XEJP is powered at 20,000 watts. But to avoid interference to other stations on 1150 AM, it reduces power at night to 10,000 watts. It uses a non-directional antenna. The transmitter is off Calle Maravillas in the San Miguel Teotongo neighborhood of Mexico City.[1]
History
While the concession for XEJP was awarded in 1936 for a station on 1130 kHz, owned by Salvador Monterrubio R., it took nearly two decades to begin broadcasts. It signed on the air on September 15, 1955. In 1964, it took on what would be its longest-running format, Radio Variedades with a wide-ranging catalog of music in Spanish.
In 1997, Radio Variedades and the XEJP call sign moved to 1320, and in return 1150 became news-formatted "Formato 21" XECMQ-AM. In October 2001, 1150 and 790 swapped formats. "Formato 21" went to 790, while 1150 adopted the Spanish oldies format "El Fonógrafo" which had aired on 790 since its 1990 launch.
