This system has been around for decades. The main repeater, 145.150 MHz (CTCSS 131.8 Hz), has a roughly 30 mile range from Buxton. To help users on the fringes using low-power, hand-held radios, UHF repeaters are used to extend the usable range of the system. To cover the three villages of Rodanthe, Waves, and Salvo, the 444.325 MHz (CTCSS 131.8 Hz) repeater was established. To cover the village of Ocracoke, the 444.250 MHz (CTCSS 131.8 Hz) repeater was established. Both of these repeaters are linked with each other as well as the Buxton repeater providing full coverage of Hatteras and Ocracoke Islands.

These repeaters are usually linked to the Dare County Repeater System to provide full coverage of Dare (and Currituck) Counties.

This system is the new one (for me). Prior to this system being put into place, many of these repeaters were standalone systems that may or may not have received much traffic. During emergencies, it was also difficult to communicate with all areas at once so this system makes it much easier to do so.

The Mamie 146.940 MHz, Kill Devil Hills (Colington) 145.110 MHz, Bodie Island 145.290 Mhz, and Columbia 442.725 MHz repeaters are all linked together with the Hatteras and Ocracoke Islands Linking System which provides coverage from the North Carolina/Virginia state line on Highway 168 to the north, Williamston on US Highway 64 to the west, and Ocracoke Village to the south. The links are all RF-based with no Internet or other commercial wire-line connectivity required.

The NCPRN DMR repeaters on and near the Outer Banks use a shared local talkgroup. This means that when using the local talkgroup (TS 1, TG 27500) on the Mamie 442.850 MHz, Bodie Island 444.9875 MHz, Buxton 444.0625 MHz, or Englehard 442.4625 MHz repeaters, your transmission will be retransmitted among all of those repeaters. This can aid in communicating up and down the Outer Banks.
