I think a few years from now all The major systems in Dallas, Ft worth, Denton, Collin counties will become one Big system similar to TXWARN P25 system in southeast TexasI'm mildly surprised that they are using the same 44A NAC that's on the Ellis County layer.
I also wonder if, at some point, they roll the Dallas P25/NCTCOG system into NTIRN. I figure Dallas Simulcast will move, but would they just leave the others where they are now?
