facilities although the powerful transmitter of XERA had been dismantled and shipped elsewhere. The station later moved to a new building where a 250kW RCA main transmitter was installed. The RCA "Ampliphase" transmitter has not been operational for many decades. Piedras Negras XEPN-AM was sister station to XER/XERA, and was also controlled by John Brinkley. XELO-AM Nuevo León Monterrey XEG-AM: In 1950 the advertising time of this station came under the control of Harold Schwartz of Chicago, who also came to represent XERB near Tijuana/Rosarito (the station made famous in the movie American Graffiti.) From the late 1960s through the early 1980s, XEG was known for its nighttime Black/R&B/Disco music programming block, transcribed from KGFJ, Los Angeles. XEG ran a huge 150kW signal at night, with 50kW daytime, on 1050 kHz. XET-AM, nicknamed La T Grande, went on the air in 1930, made the Carter Family music well known in the 1930s. Tamaulipas Matamoros XELD-TV: This station, owned in a joint venture between Romulo O'Farrill and Emilio Azcárraga, signed on in 1951 as Mexico's third television station on air, the first outside Mexico City and the first TV border blaster. It held affiliations with all major American networks, though its primary connection was with CBS. It was the only station in the area until 1953; weakened by economic conditions, new stations in the US and the deterioration and destruction of its physical plant, the station was gone by the middle of 1954. Nuevo Laredo XENT-AM: Operated by Norman G. Baker from 1933 until forced off the air in 1940; "The Calliaphone Station" (for an air-operated calliope invented by Baker) promoted a cancer-cure clinic of Baker's, essentially continuing his former station KTNT ("Know The Naked Truth") of Muscatine, Iowa, as was itself forced off the air in 1931. Brochures for the clinic urged patients to "phone 666 upon arrival in Laredo," attracting many complaints to the American Medical Association as invoked reference to Revelation 13:18, citing 666 as the Mark of the Beast. When the original XENT was dismantled, the callsign was assigned to a new and unrelated station at La Paz, Baja California Sur. Reynosa XED-AM: The first radio station in Mexico to be considered a border-blaster. XED was originally located at Reynosa, Tamaulipas, and was under the advertising sales management of the International Broadcasting Company.
