Well - there might be.  The HW noise blanker does not have the 
roofing filter in front of it.  I don't fully understand how
the bandwidth is determined - and haven't had a chance to test 
it with loud signals and an appropriate noise situation yet.

The cool thing about the DSP filter working so well is that
it is after the roofing filter - and will not be affected by
nearby signals.
