Agree with what @maus92 said. In the past, it seemed MSP Barracks moved over about a month after the region became "live." SHA shops seemed to be much slower to switch over and usually did a Shop at a time. Marlboro and Laurel have been active at times on FiRST already. MDTA might come on sooner as I have heard ICC units (police + maintenance) testing previously on FiRST. Most if not all of NRP Area 4 units already have FiRST radios. I often hear Area 4 units on Area 3 and other talkgroups. I would think Area 3+4 will be patched together as the other NRP areas are patched together. I would think the State Parks would be active before Summer if they have capable radios.
