As far as P25, NH was ahead of most of the US (for better or worse). The vast majority of Law Enforcement has been P25 for several years. However, only a few Fire Departments use P25 as a primary mode and all maintain some level of analog capability.
NH's communications landscape is much simpler than Massachusetts. Over 95% of NH operates VHF High-Band; over 99% for Law Enforcement. There are a handful of Fire Departments still on Low-Band, but typically have some sort of High-Band access. State DOT is UHF, Emergency Management is Low-Band (when used). Two cities, Manchester & Nashua use 800Mhz trunked systems; but have some High-Band access (esp. Nashua).
P25 is slow moving on the Fire-EMS side because most are volunteer and/or use toning and pagers (minitors, swissphone) to alert members. Also they have seen the coverage issues police face on a regular basis and understand analog travels farther in our granite rich, hilly environment.
As far as a "Statewide" system. No, that isn't likely to ever happen. NHSP tried awhile back to recruit local PD's so they could grab up their frequencies for a VHF trunked system. But it never materialized. NH tried 800Mhz in the 80's and it was all but a total failure; with the last user (NH Marine Patrol) resurrecting a High-Band frequency they had a few years ago.
