John,

You'd have to provide your pqact.conf for particulars, but
som basic information here:
1) ECMWF only makes a small bit of data available for free. Your patterns
are storing ECMWF parameters in separate files. The ECMWF data comes on 12 
subgrids that
can be stitched together into a global grid. 

2) The NOAAPORT broadcast (the source of the HDS grids) does contain a subset 
of what
you would find on the FTP servers. That is because NWS only broadcasts what 
there is 
a "need" for the field offices to receive (bandwidth considerations). We do 
carry
a feedtype CONDUIT which is populated with NWS ftp server files that represent 
the
full set of grids available for those data sets described at:
http://my.unidata.ucar.edu/content/data/conduit/ldm_idd/index.html

3) The names you are using for models below are old, and no longer found on the 
ftp server.
The ETA model is now known as NAM, AVN/MRF are collectively known ad GFS.
You can find additional information through the NWS docs at:
