KDKA Now Heard on HD3 Channels

CBS uses FM multicasts to expand reach of its AM news format in Pittsburgh

KDKA(AM), Pittsburgh, is now simulcasting its programming on multicast channels of the FM band. It began broadcasting its 50,000-watt signal in AM IBOC on 1020 kHz in May.

“NewsRadio 1020” is airing on the HD3 channels of three CBS Radio Pittsburgh cluster stations: WBZW(FM) at 93.7 MHz; WDSY(FM) at 107.9 MHz and WZPT(FM) at 100.7 MHz. Consumers need an HD Radio receiver to hear the KDKA programming on the FM multicast channels.

One of the two multicast channels on each CBS Radio FM station in Pittsburgh now simulcasts KDKA, 24 hours a day.

CBS Radio SVP/Pittsburgh Market Manager Michael Young said the multicast channels would expand KDKA’s program distribution and “provide our audience with additional ways to listen to KDKA’s news reporting and talk programs.”
