Jim,

The change is only in the displayed width.  Before it was the IF 
bandwidth, and now it is the audio bandwidth - for AM, that will be 1/2 
of the IF bandwidth, so 10 kHz before equals 5 kHz displayed now.   It 
is consistent with the other bandwidth displays that indicate the audio 
channel width.

73,
