Maine State Agencies

  • Most Maine state agencies will be transitioning to the new MSCOMMNET P25 digital VHF trunked system during late fall 2013.
  • See the SNE Wiki page MSCOMMNET Maine State Communications Network for up to date information on the status of the new system.
  • It is likely that some of the conventional, analog channels listed here will continue to be used after the transition to MSCOMMNET.

Maine State Police

  • Only 126 of Maine's 492 communities have their own police departments, or other regular police coverage
  • The present State Police system was constructed in 1974
  • A new statewide multi-agency digital VHF trunk system MSCOMMNET Maine State Communications Network is being deployed
  • Regional PD Nets were established to improve communications between local and county departments and the State Police. They presently see limited use and some are apparently inactive. Most inter-agency traffic is on Statewide Car to Car (154.6950 MHz)
  • Maine Forest Service Rangers are dispatched over the Forestry repeater system from three regional headquarters: Augusta, Old Town & Ashland. Rangers respond to all woods fires of significance
  • CONOPS (Concept of Operations) Interoperability channels introduced in 2006 to meet federal requirements for large incident communications. May be assigned by State Police when needed. State has encouraged all local agencies to adopt their use, however it is unclear how many have done so beyond those already in service (State Fire; Statewide Car to Car)
  • State Police also dispatch Marine Patrol (1800 #'s) & Warden Service (2100 #'s) units
  • EMA, DEP, federal units (1700 #'s), & and some local PD's also have access to the system
