Bob,

The updated sfmetar_sa.tbl file will be used to create the next new gempak 
surface file. If you are creating daily Gempak files, then this will occur
with 00Z metars. If you are creating hourly surface files, then this would 
occur with the next hours data.

You can see if DSV is in the current file with:
area=@dsv and sfparm=slat;slon;text

If the surface file was created before you added the stations to the table,
slat and slon will be 0.00...but the text and decoded report will be there.
If the station is in the file, you can use sfstns to update the station
information with your new station table (you shoud make sure the LDM is
not writing new reports into the file when you do that...otherwise the
file will get corrupted). If the number of unknown stations exceeded the -a
additional stations, then there may not have been space to add the station
to the table initially- but will be there when the new file is created.

If the station is not in a newly created file, then make sure you have 
spaces and not tabs in the sfmetar_sa.tbl entry.
