I ran across a data channel on 408.150 that is likely from the KC or Topeka area. The 996 didn't know what to do with it for a while but now it says LT System. I haven't seen any IDs come up yet.
Right now Im hearing a Motorola Control Channel on 408.15. SysID 6818 which I think is USP @ Ft Leavenworth. Here are the system freqs from the last time I was able to hear the system.
