KNX (AM)

KNX (1070 kHz) is a commercial AM radio station in Los Angeles, California. It simulcasts an all news radio format with sister station 97.1 KNX-FM, both owned by Audacy, Inc. KNX is one of the oldest stations in the United States, having received its first broadcasting license, as KGC, on December 8, 1921, in addition to tracing its history to the September 1920 operations of an earlier amateur station. The radio studios and offices—shared with KNX-FM, KCBS-FM, KROQ-FM, KRTH and KTWV—are located on Wilshire Boulevard, along Los Angeles' Miracle Mile.

KNX holds a class A license as one of the original clear-channel stations. Its 50,000-watt non-directional signal is heard throughout all of Southern California in the daytime. When conditions are right, it can be picked up at night throughout much of the Western United States and parts of Mexico and Canada. The station is even received by DXers in Hawaii and across the Pacific Ocean. The transmitter site is in Columbia Park in Torrance, near Hawthorne Boulevard (California State Route 107) and 190th Street. KNX is authorized to broadcast a digital HD Radio signal.

KNX and KFI are the local primary stations for the Los Angeles Emergency Alert System. They are responsible for activation of the EAS when hazardous weather alerts, and disaster area declarations are issued.
