KNX (1070 kHz) is an all-news radio station in Los Angeles, California, USA. The station operates on a clear channel and is owned by CBS Radio. KNX broadcasts from facilities shared with sister stations KFWB, KCBS-FM, KTWV, and KAMP on Los Angeles' Miracle Mile, and maintains its transmitter and antenna array site at Columbia Park in Torrance northeast of the intersection of Hawthorne Boulevard and 190th Street. The station also broadcasts a high-definition HD Radio signal, streams online through its web site, and simulcasts on the FM band on the HD2 channel of KTWV (94.7 MHz).
KNX's notably powerful signal (esp. at night hours) can be heard in large sections of the United States, Mexico, southernmost Canada, into Alaska and Hawaii. But a few reports of KNX being received across the Pacific Ocean on some radio sets from Japan, Philippines, Australia, New Zealand, Panama, Colombia, Peru and Chile are not far-fetched. Many 50,000+ watt stations on coastal cities worldwide have the ability to propagate over very long distances.[citation needed]

History
KNX began broadcasting under the callsign 6 ADZ on September 20, 1920.[1] By 1922, the station was in competition with many other stations in the area, all sharing a single wavelength of 360 meters (roughly 833 kHz). The AM broadcast band had not been defined at the time, and stations were required to share frequencies.[2] The station became KNX on May 4, 1922.[3]
In 1929, the transmitter of the station was upgraded to 5,000 watts, and in 1932, was raised to 10,000 watts of power. During this time, the station changed owners and was operated by Western Broadcast Company. A year later, in 1933, the station moved studios to another part of Hollywood, and was allowed to raise its power to 25,000 watts. The following year, the transmitting power was raised to 50,000 watts, which the station continues presently.[4]
CBS radio began operating on KNX in 1936. In 1938, the CBS Columbia Square studios[5] were dedicated for KNX as well as West Coast operations for the entire CBS radio network; several legendary performers from the Golden Age of American network radio broadcast from there, including Jack Benny, Bing Crosby, George Burns, Edgar Bergen[6], and during the early 1960s, actor Bob Crane.[7]
KNX became an all-news station in the spring of 1968 [8]; its first major breaking news coverage was of the assassination of Democratic Presidential candidate Robert F. Kennedy, in the Ambassador Hotel in Los Angeles, in June of that year.[9]
In August 2005, KNX moved out of Columbia Square after 67 years of operations there, and began broadcasting from new studios on Wilshire Boulevard in an area known as the Miracle Mile.[6]
In 2009 KNX adopted the slogan "All News, All the Time" for its promotions and advertising. It was previously used for 40 years by KFWB, KNX's historic rival in the news radio wars before both became sister stations in the 1995 merger of Westinghouse Electric (KFWB's owner) and CBS. KFWB's format change to news-talk in September 2009 now leaves KNX the only all-news outlet in the Los Angeles area, which is now emphasized in its alternate slogan, "L.A.'s only all-news radio station". A slight variation, "Southern California's only all-news radio station", is played at :30 past each hour before the news headlines.
Broadcast Schedule
KNX features CBS News at the top of each hour. Traffic and weather are together on the fives, (:05, :15, :25, :35, :45, :55). Business news from the station is at 10 and 40 past the hour and sports is featured at 20 and 50 past the hour. Several talk programs can be heard during the day. A list of programs can be found on the station's website.
