[2] 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.
El Fonógrafo moved to XEN-AM 690, sharing its musical format with programs from talk station XEQR-AM 1030.
In January 2019, the IFT approved GRC diplexing XEJP with XEN at its San Miguel Teotongo transmitter site and reducing daytime power from 50,000 to 20,000 watts.
[4] XEJP began testing from the new site on August 6, 2019 and resumed regular programming as an Acustik Radio station on September 2, 2019.
That same day, Acustik began programming two other former Radio Centro AM stations, XEUNO-AM in Guadalajara and XEMN-AM (later changed to XEFB-AM) in Monterrey.
