I am running Gempak 5.10.3 on Fedora Core 6 at home.  I installed from source, 
and everything works fine.  I have a NOAAPORT feed providing data, and that too 
is working fine.  All single site radar data is visible in NMAP and looks great.

I am attempting to use nex2gini to created mosaic radar images.  I am using the 
example settings from chiz for creating a 1km mosaic.  The program runs without 
error, and creates a file of proper size (compared to examples of good ones 
from other sources).

My problem is, the navigation is messed up on all the images.  Data is 
displaced by 50-100 miles.  Looping the images in NMAP show that the errors are 
consistent.  I have made numerous attempts using different projections, gareas, 
station tables, kxky values, etc.  All images come back with displaced nav when 
displayed in NMAP or gpmap.  Running nex2img results in the same thing.

This morning I cleaned and remade GEMPAK.  No errors.  No change in output.

Anyone have any ideas?  I'm stuck.
