KLAA (AM)
Because 830 AM is a United States clear-channel frequency, on which WCCO in Minneapolis is the dominant class A station, KLAA must reduce power to 20,000 watts from sunset to sunrise.At night it feeds power to all three towers in a directional pattern, projecting most of the signal westward to protect WCCO.While mountain tops are good for FM transmission, AM stations need low, flat land for the best signal propagation.In 1991, the station changed its callsign to KPLS, and began airing a Spanish language talk radio format as "La Voz" in January 1992.After the sign-off of Radio AAHS in January 1998, the parent company, Children's Broadcasting Corporation, needed programming for the network of stations until they could find buyers.[4] During this period, the station was owned by John Lynch, father of the veteran National Football League cornerback of the same name.KPLS had close ties to the Orange County business community and was the flagship station of the Anaheim Ducks hockey team.Talk show hosts included Rusty Humphries, Glenn Beck, Dr. Roy Masters and Michael Savage.The station aired the team's Saturday games during September and October when KSPN, the flagship from 2003 to 2007, carried USC Trojans football.
