Stepping through 2.1 and 1.0, I can hear the bandwidth changing, but the
graphic doesn't change until I get to the .250 filter, where it is correct. 

I replied:

        I'm now in front of my rig using 3.63 firmware.  The graphic steps
in my rig are at 2.8 (nothing wider installed so I won't see the widest
graphic for AM/FM), 1.0, 500 and 250.  If you look carefully at the graphic,
you'll see it has a maximum of 5 resolution steps, so you'll never see a
change for intermediate filters like 2.1, 1.8, 350, etc.  If you aren't
seeing the step at 1.0, be sure your 1.0 filter is enabled in your XFIL
configuration.

73,  Bill
