I believe they're using the same talkgroup as Hibbing, TG 2125. Hibbing ship is Life Link 6, Cloquet ship is Life Link 7.
They also have their new Brainerd base, which is Life Link 8. From what I have been hearing, they have been using TG 2117, which I have in my scanner as their "Tac" channel.
Is the cloquet base new? I haven't monitored in hibbing for about a year but last I did I don't remember hearing cloquet traffic on the hibbing talkgroup.
