GEMPAK location of KP69

GEMPAK folks,

It has come to my attention that the GEMPAK station location file has KP69 
listed as
Elk City (RAMOS), with a lat/lon of 45.82, -115.43.  In reality, KP69 is an 
ASOS at
"Lowell" Idaho with a lat/lon of 46.144, -115.596 and an elevation of 451 
meters (or
1480 feet).  I would appreciate it if you could change this.  At various times 
over
the past 8 years I have had people fix this in various places - but it always 
gets
changed back - perhaps you can get it changed on the "master" list somewhere.
