New Hampshire utilizes a common channel plan for accessing hosiptals for incoming patient trnsports and patches. This is done using separate CTCSS (PL) tones for each hospital. When an ambulance needs to call the hospital, they swicth to the channel associated with that hospital and calls them on the given Med Channel. In addition, other channels have been assigned for coordination and tactical uses. Some of the channels, such as Med-3 and Med-5, have rarely seen any use. While Med-1 is widely used and Med-2 is often used. EMS Tac-1 (Med-4) and Tac-2 were established under the new Fire-EMS Grant plan. Tac-2 is designated as the Helo LZ Coordination frequency statewide.

  • NOTE: At one time several dispatch centers could act a medical control dispatch for larger incidents. These "RCC" (Radio Communications Center) facilities were typically located in existing Dispatch Centers and could patch ambulances into the hospitals using several channels.
    There are no longer any RCC facilities
