Detroit Pistons moved to CBS due to HD Radio interference?

Pete Skorich, Detroit Pistons Director of Broadcasting, addressed a rumor that  RBR-TVBR heard regarding a rate reduction in The Detroit Pistons contract with Clear Channel’s Sports WDFN-AM 1130 kHz over poor reception in the evenings. Details had it that 50-kW KMOX St. Louis (1120) and 50-kW WRVA Richmond (1140) were killing WDFN’s nighttime signal because of their skywave HD Radio carriers on 1130. Well, Skorich tells us there was no rate reduction but instead a complete move to CBS Radio’s The Ticket (WXYT) simulcast of 97.1 and 1270 some two years ago.
But he did note it was because of reception complaints: “That was one of the components, and we were with them for five years. They had a weak signal and we were getting a lot of people that could not hear us. It could have been [because of] HD Radio, but at the time we were totally unaware of it.”
