CBS Radio in Philadelphia rebranded WRDW-FM five months ago from Wired 96.5 to Amp Radio (Top 40). On Friday the station added two live announcers after going jock-less since the change. According to The Philadelphia Business Journal, Mike Adam (pictured) will host afternoon drive and Jill Osterman will host middays. Adam worked at 92.3 Amp Radio in New York and WIOQ in Philadelphia. Osterman was most recently the afternoon drive host at HOT 95-7 (KKHH-FM) in Houston. Both start September 10.
