KTNQ (1020 AM) is a radio station licensed to Los Angeles, California, with a Spanish News/Talk format. It is owned by TelevisaUnivision. From its original licensing on March 13, 1925 until 1955 it was called KFVD. The station has studios on the Univision Broadcast Center building located on 5999 Center Drive (near I-405) in West Los Angeles, and the transmitter is located in the City of Industry. The station was originally restricted in its broadcast hours, signing off at local sunset to protect 1020 KDKA Pittsburgh from nighttime sky wave interference. Later, the FCC allowed geographically spread daytime stations to operate at night with a directional pattern away from the previously protected station. 1020 kHz in Los Angeles was then allowed to operate as a 24 hour station.
