WBT was very strong here in Pennsylvania last night. Watching the  
overnight recordings I made on the SDR-IQ receiver, the IBOC noise on  
especially the upper, but also the lower sidebands were very evident  
when I checked the recording at 1am EDT. The visible spectrum display  
showed 1100 WTAM Cleveland overpowering WBT's IBOC at times, but with  
nothing strong on 1120 that was mostly hiss.
