KDKA-AM (1020) morning host Larry Richert has been named the Public Address Announcer for all home Steeler games at Heinz Field. He takes the job over from Randy Cosgrove who resigned in April after 15 years as announcer at both Heinz Field and the former Three Rivers Stadium. Working for the Steelers is nothing new to Richert who has voiced NFL and Steelers Highlight videos for a number of years. (Trib)
