Did you figure it out? I have been passing through Jeff Davis Parish 5 days a week and I only hear a few transmissions on the 800 LTR system. These transmissions only amount to license plate checks every now and then. No calls dispatched on these frequencies. I also scan all the frequencies that they are licensed for in UHF and I have not heard a peep. No control channel either. Next time you are in the area, try this: If you have a pro-93, 95, or 96 use the police / fire search feature. When on this screen, you will see "Group 0123" on the third line. Press 0, 1, and 3 to turn these groups off, leaving only group 2 active. This will cause the scanner to search only the UHF frequencies that are allocated to public safety (group 2). Groups 0, 1, and 3 are VHF Lo, VHF Hi and 800 respectively. I will try the same thing tomorrow as I pass through Jeff Davis and I will let you know if I hear anything. I tried VHF the other day and I didn't hear anything.
