Which state? There are "Ft. Campbell" in more than one state. To search, go to http://www.arrl.org/
and on the upper left side of the home page click on "clubs".....which will open a page where you can search by name or zip code, etc. and you can set distance parameters also. Of course (as far as I know) they only list ARRL affilitated clubs....but most Ham clubs are ARRL affilitated anyway.
