Are you sure this is a Level II file?  From the looks of the path, it
might be a Level III file which the IDV only reads through ADDE servers.
N0R products are the Base Reflectivity Tilt 1 Level III products 
usually.

The IDV 1.1 version should read bzip2 compressed or uncompressed Level II
files.  

Please confirm this is a Level II file.  You could look at the size
(Level III files are on the order of 10's of kilobytes, Level II files
are on the order of 100's of kbytes (compressed) or megabytes (uncompressed).
You could also do an octal dump on Unix (od -c) on the file and if it's
a Level II file, you should see the first few characters be:

ARCHIVE2

or 
AR2V0001 

If it is a Level II file, could you put it out on an FTP/HTTP server 
so I can download it and take a look?

Thanks.

Don Murray
