Dan Goss at philly.com hears the simulcast could start around Labor Day. According To Goss, WIP program director Andy Bloom said that he could neither confirm nor deny the rumor but that there were rumors about the stations all the time. CBS Radio market manager Marc Rayfield said essentially the same thing.
One possible sign of 'YSP's future could be Danny Bonaduce, the biggest name and salary at the station. His most recent contract was renewed for only one year, according to Goss.
