[MilCom] 254.2 Again!?

[vampire11 at comcast.net]

Ok just when I thought 254.2 was explained and the mystery was solved, This happened. I currently have the that same Calgary Alberta approach controller on 254.2 right now, BUT I am hearin the aircraft answer him back. The VHF side is gettin in the sat now. I hear the civilian aircraft on VHF answering the controller.  I have never heard of a airport rebroadcasting all of the VHF side on UHF before. The only thing that is usally similucasted is the controller on UHF. Any ideas anyone? I got this all recorded as always.
