As Wayne has repeatedly stated here the bandwidth display is 
AUDIO bandwidth i.e., the output of the DSP.  If you get it 
through your head that the bandwidth display shows the audio 
bandwidth, the current display is correct in all modes without 
any change.  I do not know if/how that will change when FM is 
enabled.
