US Park Police Eagle helicopter went to Dahlgren on Friday night for a medevac of a burn patient. Dispatch wanted them to use Statewide EMS to communicate with NDW Engine 28, but for some reason, they said they couldn't get it, so both Engine 28 and Eagle switched to Charles Co 10A3 (after some issue with Eagle not having Marine Channel 10A12, only regular 10A12 in their radios).
