When monitoring TG-7024 (FMUP) you'll hear interactions between the ICC and the DNR Forest Management Units located at Baraga, Crystal Falls, Escanaba, Gwinn, Newberry, Sault Ste Marie, and Shingleton in addition to the aircraft engaged in fire patrols.
Communications activity on this talkgroup varies seasonally. Field units responding to fires break off from FMUP and continue to communicate on designated Fireground or Forest Mangement Unit talkgroups and often work talk directly from unit to unit on VHF FM when onsite.
