[Drake] R4C Filter loss/mode independent of bandwidth selection

1) Can anyone tell me about what the typical R4C 500 cycle filter loss is 
compared to the stock SSB filter?  I haven't measured with anything accurate, but 
the peak drops from about 20 over S9 to about S9 when switching to the 500 
cycle filter, and wondered if that's typical or excessive - the filter otherwise 
performs well; and

2) Is there a mod for making mode and bandwidth selection independent - I've 
got an early R4C and would like to have multiple AM bandwidths available.

Thanks, Scott
