The State Police (along with certain other agencies) system is OpenSky (for now).OpenSky is not scannable with any scanner. They starting using OpenSky over a decade ago, so "soon" might indicate a very old webpage or thread.
According to the RadioReference Database (RRDB), York is P25 Phase 2 with no encryption listed that I see. A P25 Phase 2 scanner should be fine. (actually all the talkgroups are listed as Phase 1, so they might not even be using Phase 2 at this time).
Dauphin is listed as P25 Phase 1, with a mix of encryption and non-encryption. However the EMA is listed as encrypted so you may be out of luck on that specific agency.
Harris makes P25 systems too, so don't get confused assuming Harris means OpenSky. (Harris P25 are monitorable as long as encryption is not present on the talk group you wish to listen to).
