Mark, One thing to look into is exactly how the radar products are being processed by the downstream site. A too-simple implementation of an LDM NEXRAD2 decoder can result in product loss even though all products are received. This happens when the "pqact" process runs out of file-descriptors and data-products arrive out-of-sequence. See <http://www.unidata.ucar.edu/software/ldm/ldm-current/basics/pqact.conf.html#output-file%20limit> for more information. Incidentally, you might like to know that the extended regular expression substring "([0-9]|[0-9][0-9]|[0-9][0-9][0-9])" that you used in your investigations can be simplified to "([0-9]{1,3})".
