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.
