Hi Jeff,

You don't have to generate the FNEXRAD feed - it's already done for
you.  You should simply request FNEXRAD from motherlode.ucar.edu.  Then,
be sure to add that feed to the 'allow's for your downstream sites so
they can get it too. 

(If you want more info on this see
http://www.unidata.ucar.edu/packages/ldm/receivingRadar.html.)

FYI, at this point in time FNEXRAD is only generated on motherlode. 
Since it's only a small amount of data, we think this is an ok
distribution mechanism, although it is a single point of failure.  The
alternative is to run the software to generate the FNEXRAD data at all
the ingest sites.  We are considering if and when we need to spend the
effort to do this, so things might change in the future.

Please let me know if you have any further questions.

David, will you please let me know when you are receiving this feed? 
Thanks!

Anne
