It's pretty easy to miss the obvious.  Well it iwas for me anyway.  

Set up the radio for LSB with a 2-3 Khz bandwidth.  Then use PBT 
to shift the passband to 1Khz or something.

Now with Low cut, both the display and the numeric values for 
bandwidth and PBT show the result that would be expected .. the 
low end of the passband slides up, while the high end stays put.

For high cut (and I missed this obvious point because I didn't have 
passband shifted), the high end of the passband slides down while 
the low end stays put.  However, the numeric value of PBT in the 
display does not change, and should -- which was what I think Scott 
indicated needs to be fixed.  

And this was what led me, anyway, to believe that Hi cut was just 
equivalent to BW, which it clearly is not.  Hi cut does indeed change 
both BW and PBT simultaneously, although it is not properly 
reflected in the PBT numeric value.
