Hello Paul,

From the header in vors.tbl, it appears the data first came from the Aviation 
Weather Center (AWC).  From their website I can find 

http://aviationweather.gov/static/info/advsry/
and 
http://aviationweather.gov/static/docs/advsry/advisory.txt

Their file has 323 entries while the GEMPAK vors.tbl has 387 entries.  Some of 
the GEMPAK data tables include stations no longer used operationally so that 
archived data of any manner can be displayed.  That is likely why the 
NAWIPS/GEMPAK table has more entries than the AWC maintains.
