During the Station Fire in 2009 , NBC owned-and-operated station KNBC in Los Angeles temporarily replaced programming from NBC Plus and Universal Sports on its subchannels with standard-definition feeds of its two Spanish language sister stations – independent station KWHY-TV ( now a MundoFox affiliate , since sold to the Mueriello Group ) and Telemundo owned-and-operated station KVEA – as an emergency measure in the event that the transmitters of those stations were destroyed or disabled as the fire reached Mount Wilson , where the transmitter facilities of most Los Angeles area stations are based . <!-- As utilised by NHK in Japan--> In rare cases , digital television broadcasters have included a service known as DTV radio , in which the audio of a commonly owned broadcast radio station is simulcast over a subchannel ( for instance , KPJK in San Mateo , California broadcasts former FM sister KCSM on its DT3 signal ) . WANN-CD in Atlanta offers six radio stations owned by iHeartMedia , in addition to ten television channels
