There is also additional information on this site. It was accurate as of 2004 when I lived in Ohio. However, I am not sure if the frequencies still apply in other areas away from the base.
ALSO: Just in case anyone else did not know what a JDAM was (see above posts) look at this web site. I found it interesting...
