You can easily look up the patterns at fccinfo.com, or the FCC's AMQ 
site (http://www.fcc.gov/mb/audio/amq.html).  From your observations, 
it appears that they are doing a pattern change, but I still think 
that their night pattern is not what it should be.  I'm at 60 degrees 
azimuth from them, and should be deep within their eastern null.  
They should be in the mud here, but instead are usually the dominant 
signal, and often were even before CBA's demise.  Actually, WTIC's 
IBOC is now the dominant 1070 signal here now, but CHOK is always 
there in the hiss at night.
