Hi Victor, What GEMPAK version are you using? I can't say much off the top of my head because I'm able to decode the grib2 RAP #236 files without error (downloaded from NCEP NOMADS). I dropped back to GEMPAK 5.11.4 to see if it may be a grib table issue but decoding was fine then as well. Maybe we're using two different files? Can you point me to where I can find the exact files you're using?
