Are you sure these are Level II files and not Level III?  I ask becuase
the file name has SDUS52 in it which is the product ID for Level III
data on the NOAAPORT feed.

It can read Level II and Level III data so if it's Level III that
would make sense.

Does the NCDC viewer have that option?  

We are working on revamping the radar data reading which will
use the netCDF for Java library.  That means that we might be
able to write them out in a netCDF format in the future.  But
that won't be available for a while (maybe fall).
