Hi Greg, I played with this last night to confirm what I had found out before, the GP programs are unable to re-project the site radar projection written into the file. I saw Daryl's suggestions on gembud and I recommend either: use his re-projected level 3 or create your own with nex2img. I have used nex2img/nex2gini before on single stations by controlling what is in a local (pwd) copy of the table nexrad.tbl for STNFIL.
