I feel like we go over this on a regular basis. The agency rollouts are happening. Each agency is moving at their own pace. So far, PennDOT has been rolling out new radios following the system rollout (started in NW, moved to SW, then SC). I would imagine that District 5 and 6 will come online during 2020. But, only PennDOT knows for sure. If you're not seeing any talkgroups active for PennDOT, then you just need to sit back, relax, and wait for PennDOT to get their equipment rolled out in that area.
DCNR has been reported active in western PA. Presumably, they will roll out equipment across the southern portion of the state and the NW area during 2020 with the NE and NC areas to transition last since the network buildout is still ongoing there.
So, just keep monitoring and let us know what you hear and when. Nobody here has the migration schedules for each agency. And, if they do, they ain't talkin'.
