Gregory, Thanks for the information, it sounds like the U.S. NOAA Office of Oceanic and Atmospheric Research is associated with the NWS. The problem I have is what parameter table is used to decode the data? The NWS has about 14 different parameter tables. If you have a copy of the table, I could compare it to the ones I have installed or implement it in our list of tables. Thanks, Robb...
