Camp Atterbury Security & Fire; Job Corps Facility
Info obtained this past weekend (3-27-10) is that the Camp Atterbury MPs are exclusively on the SAFE-T system now. I heard the MPs on TG 39936. The Fire folks are supposed to be on 39920, but I did not hear anything. Two other TGs on the Radio Reference list are 39904 (JOC) and 39776 (MP2).
Other Atterbury operations are on two 138 freqs:
138.0375 (Range Control, with an input of 141.4875), and
138.7125 (Logistics/Transportation details).
Both of these use a PL of 151.4.
I suspect more 138-144 channels, but I didn't have much opportunity to find them, due to limited time in the area.
From a source, all of the old channels are gone, with the radios shipped to Afghanistan.
I also was told that the Job Corps facility is to be moved to Ft. Benjamin Harrison in Indianapolis soon. The Army is taking over again a lot of the land used by the Job Corps, and Johnson Co. Parks, and the Indiana Fish and Wildlife Area. The Army apparently is expanding it's operations at Camp Atterbury, especially related to training for Afghanistan and Iraq.
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?
