He covered it all. It's Range Control and Transportation on the 138 frequency, M.P.'s are on SAFE-T. I have a live feed during the week from 7AM-3PM where I include all Camp Atterbury frequencies listed by Radio Reference and I only ever hear the MP's, Range Control and Transportation. I use to be able to hear the Aircraft bombing/strafing runs but I don't include the aircraft frequencies because sitting next to my computer causes problems with those frequencies. Maybe you could drive around Camp Atterbury with close call on and see if you can find anything more mysterious?Do you have anymore info??? I would like to find more info rather there is any more frequencies that I dont know about???? Please post or private email me..
