That didn’t take long. Less than a year after Jam’n 94.5 tapped onetime Kiss 108 DJ Frankie Vinci and former “Real World: New Orleans’’ cast member Ashlee Feldman to take over the station’s morning show, the pair has been replaced. Jam’n 94.5 debuted “The Breakfast Club,’’ a syndicated show that can be heard on 60 stations across the country, Thursday. The show features Charlamagne Tha God, Angela Yee, and DJ Envy. A station rep said Frankie and Ashlee are still employed by iHeartMedia.
