History


XEAC and XEAK

XEAC began broadcasting from the Agua Caliente resort in Tijuana on January 7, 1934. It broadcast at 820 or 815 kilohertz. By 1936, the station was owned by Jorge Rivera. In 1938, it was listed as transmitting on 980 kHz with 5,000 watts.
NARBA The North American Regional Broadcasting Agreement (NARBA, es, Convenio Regional Norteamericano de Radiodifusión) refers to a series of international treaties that defined technical standards for AM band (mediumwave) radio stations. These agreem ...
prompted a major shuffling of radio station frequencies, and XEAC wound up on 690 kHz. More than 15 years later, this would play a vital role in changes at the station. In the early 1950s, XEAC spawned a television station, which was initially assigned the call letters XEAC-TV but changed to

before signing on. In 1957, a new group known as California Broadcasters, Inc., with headquarters in the Knickerbocker Hotel in Hollywood, was formed by Rivera to manage U.S. sales and programming rights to the station, which changed its call letters that year from XEAC to XEAK. In 1958, the concession for XEAC was sold to Radiodifusora del Pacífico, S.A. While XEAC had continued to operate at 5,000 watts, it was easy to upgrade it to 50,000, as protection of Canadian Class I-A CBF

would be relatively straightforward—as happened in the change from XEAC to XEAK. Ultimately, the Tijuana-based AM 690 was assigned Class I-B status. XEAK was known as "The Mighty 690", a moniker that its XETRA-AM successor used in later years. The Mighty 690 was a

Enter Gordon McLendon

On May 6, 1961, XEAK yielded to XETRA (always written XTRA in the United States press and only announced as such in Spanish during station IDs), known as "X-TRA News" and describing itself as "everywhere over Los Angeles". X-TRA News was a primarily "rip-and-read" operation in which two anchors traded off fifteen-minute shifts reading the

format, known as "X-TRA Music". After this, McLendon divested his interest to the concessionaire.


XETRA in the 1970s and 1980s

AM stereo was first demonstrated on XETRA in the 1960s using the Kahn

system. These early attempts actually required the listener to tune in with two radios, one off-tuned to the left of the frequency for the left channel and the second radio off-tuned to the right, as AM stereo radios capable of decoding the Kahn signal were never licensed or built at the time. Later tests were run via US and Canadian-based stations. AM 690 is no longer operating in AM stereo. In succeeding decades, XETRA switched formats numerous times. During most of the 1970s, XETRA continued as a beautiful music station, competing for San Diego listeners with KJQY on the FM dial. As the easy listening format began to decline in the late 70s, XETRA switched back to Top 40, once again billing itself as ''"the Mighty 690"''. Later, the station switched to an

XTRA Sports

Shortly after, XETRA had a brief stint as a news/talk station, carrying syndicated programs such as

In 1996, the concession for XETRA was transferred to XETRA Comunicaciones, S.A. de C.V. In the latter part of the 1990s and most of the 2000s, XETRA simulcast with Los Angeles station KXTA to give listeners in the Los Angeles area two frequencies to hear the programming. The station's best-known sportscaster on XETRA was Lee "Hacksaw" Hamilton, who hosted a nightly sports talk program from 1987 until 2005, and was also the play-by-play voice of the Chargers from 1987 to 1996. Hacksaw is famous (and infamous) for his "best 15 minutes in radio" with "Hacksaw's Headlines" and using such phrases as "I am bleeping brilliant!" Nationally syndicated sports talk host
