What time is Howard Stern on the radio?

I just updated my XM radio in include best of sirius. I went on the Howard Stern website that says live episodes are on 6-9am est Mon-Th. Then they repeat the show from the previous day all day. However for the past 3 days even at 7:30am it has just been clips from past shows and my radio has been reading "History of Howard" So when are the new live episodes on?
