 signal, streams online, and simulcasts on the FM band on the HD2 channel of KTWV (94.7 MHz).

The station's antenna array includes a tall main antenna (195 electrical degrees; optimum and much better than average for a Class A station's main antenna), and a shorter emergency antenna (135 electrical degrees; much better than average for a Class A's emergency antenna but inadequate for a Class A station's main antenna), with only one antenna being active at a time. An experiment in the 1960s which utilized these antennae in a directional setup during the daytime, only, was abandoned and the emergency antenna was later relocated when much of the site was dedicated as a park. The residential area to the immediate south of the main antenna was formerly the site of the emergency antenna. The ca. 1936 main antenna was replaced after it was destroyed by a terrorist in the 1960s (KNX did not, then, have an emergency antenna, and with the subsequent replacement of the destroyed main antenna, an emergency antenna was installed as well). Non-directional Class A stations are expected, and are, with few exceptions, required to have emergency antennae.

With the demise of Canadian station CBA (AM), KNX remains the only Class A station on 1070 kHz in North America. Formerly, KNX had shared 1070 kHz (1050 kHz before 1941) with CBA.

History

KNX began broadcasting under the callsign 6ADZ on September 20, 1920. By 1922, the station was in competition with many other stations in the area, all sharing a single wavelength of 360 meters (at roughly 833 kHz). At the time, the AM broadcast band had not yet been defined, and stations were required to share frequencies. The station officially became KNX on May 4, 1922.

During the 1920s KNX, like most stations across the country, changed frequencies several times, landing on 1050 kHz as a result of the Federal Radio Commission's reconfigurations of the AM radio band in 1927 and 1928. In 1929, the station's transmitter was upgraded from 500 to 5,000 watt

s, and in 1932, was raised to 10,000 watts of power. During this time, the station changed owners and was then operated by the Western Broadcast Company. In 1933, the station moved its studios to another part of Hollywood, and was granted permission by the FCC to raise its output to 25,000 watts. The following year, KNX's transmitting power was raised to the nationwide maximum of 50,000 watts, which the station continues presently. It changed to its current 1070 kHz channel in 1941.

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.
