They're not required to stay with the narrow analog bandwidth when the 
IBOC goes off, and not all do. WLS in Chicago even turns their AM stereo 
back on at sunset.

It's trivial, in a modern Omnia or Orban processor, to set up timer 
schedules that will adjust processing depending on daypart. We do it at 
WXXI in Rochester for the University of Rochester FM that we manage, 
WRUR, which needs different processing depending on whether it's 
simulcasting our news-talk AM, running a AAA format we produce during 
the day, or running student rock mixed with various obscenities at night...
