It appears that Flight For Life Waukesha/Milwaukee are now using a talkgroup on the Waukesha Co. TRS to communicate back to the Communications Center at Crites Field in Waukesha (33328). I heard them referencing it as Ch.1. The talk group is in addition to the one they use to communicate with fire departments coordinating there Landing Zone Operations which is 13168. The Helicopter side is very clear while the communications side is kind of staticy.
