Don't know why there are two, but either is close enough. The location that will be used for the decoders is in the station database. Information about stations from the database can be listed using STNLIST in McIDAS-X 7.7x: STNLIST KVVV etc. >The problem comes when MCIAS plots a map of station IDs. >When I ask MCIDAS to plot station IDs, KVVV shows up near the NW corner >of Minn., while it actually is located much farther South, near the >"bump" of MN that extends into South Dakota. I don't see this here using 7.7. The output I am seeing can be viewed at: http://www.unidata.ucar.edu/staff/tom/stnlocs.gif KVVV is just below the western bulge. >This is the error that was the basis of my original message. >Evidently the file that includes the map plots for station IDs >has KVVV in the wrong place. Not in 7.7. >Sorry I was not more specific in the first place. Please let me know if the system you are using when seeing the problem is a 7.6 one (meaning that the machine on which the decoding is being done is using the 7.6 station database). If it is, the remedy is upgrading to 7.7 on the machine running the XCD decoders. If it is already a 7.7 one, the rememdy might be upgrading to the current addendum for 7.7. In either case, please let me know if the plotting continues to be incorrect.

Another reason to get on with the upgrade. Alan
