Just wanted to let everyone know that may live close to Camp Atterbury in Edinburgh, IN that range control is a very active frequency. 138.0375 broadcasting in the clear. Radio checks required every hour at the bottom of every hour. Heard them talking about "UAV" today and about being careful because of the weather. I can actually pick up this frequency from Seymour which is about 30 miles south. Good test of your scanner's conventional channel sensitivity.
