Hello all, I am not sure if I am in the right group here, but my question has to do with the TDOT help vehicles on the TACN system. Are they not in the clear? I have never heard any traffic on their talk groups. I have also spotted 700/800 antennas on TDOT trucks and would like to monitor them. Thanks for any help. I do lot of reading in forums but don't post much and haven't seen any information regarding either group.
