I've been watching the TXWARN question for a while, because I suspect we'll eventually see the same issue (operation in a mixed-mode configuration of Phase I FDMA and Phase II TDMA) on the Michigan MPSCS system as it converts to Phase II in the future.
Paul Opitz posted a comment regarding the TXWARN system this morning on the Uniden forum that says in part " (Phase 2 systems use a different control channel datastream than Phase 1 systems). If it is not a true Phase 2 system (i.e. it is still using a Phase 1 control channel, which would make it an X2 TDMA system)". This got me to wondering - do the older radios that are still operating FDMA understand the Phase II Control Channel data stream or does a true Phase II system revert the CC datastream when a FDMA radio requests a channel assignment, or ??? Or maybe the question is - is TXWARN true Phase II or X2 TDMA?
