Howard briefly mentioned going down to one channel. Who knows if he's serious, but here's how I'd do it:
Monday and Tuesday
7am - Howard live until he finishes
Until 11 - This Day In Howard History
11am - Wrap-Up Show
Noon - Howard, WUS and Howard History replays
Wednesday-Friday
7am - Segments of old shows aired in 4-5 hour blocks.
Friday night: Any of those special shows they do with the musical artists. Hell, this would only add to conspiracies, but air the live interview for 45-60 minutes, then do the full interview (two hours or more) in this time slot. Not everyone wants to hear the big interview of the week, but if you do, here it is. If not, there's plenty of other stuff on SiriusXM.
Saturdays: Go deep, deep into the archives with content from the 80s and 90s.
Sunday: Reair Monday and Tuesday stuff to prep for the new live shows.
