Robert,

I think you know this but...

ldm-5.1.3 has mods to supply the NEXRAD feedtype from the NOAAport stream,
here's the release note:

                Modified pqing to (1) filter out products with ID
                SDUS5* and put them under the new NEXRAD feed type, 
                (2) fix bug allowing AFOS products to be handled
                properly, and (3) switched default behavior pertaining
                to -5 option - now default behavior is to exclude a 
                product's sequence number in calculating the checksum.


Your ldmd.conf configuration is correct.  Using ldm-5.1.3 version the 
ldmadmin watch command will show NNEXRAD products arriving.
