OBRA repeater and gateway summary
| System | Location / Role | Mode | Known Operating Detail | Use |
|---|---|---|---|---|
| W4PCN 146.940 MHz | Mamie / Powells Point | Analog FM | PL 131.8 Hz listed in local RepeaterBook export. Currently tracked on the home page as down due to antenna issue. | Wide-area local voice and hurricane season coverage priority. |
| Mamie BrandMeister DMR | Mamie DMR site | DMR | Color code and talkgroup access controlled by OBRA programming standard. BrandMeister use is flexible and hotspot-friendly. | Digital voice access, OBRA talkgroups, and training. |
| Mamie PRN / NCPRN | Mamie DMR site | DMR / IPSC-style network | More tightly controlled talkgroup routing and timeslot discipline than BrandMeister. | Regional digital voice with stronger engineering control. |
| W4PCN 145.110 MHz | Kill Devil Hills / KDH | Analog FM | Shown on the OBRA home status panel as KDH 145.11 MHz. Confirm PL, offset, and linked status from the repeater book before publishing a printable chart. | Central Outer Banks local voice coverage. |
| Skyco Winlink RMS | Skyco / Dare County support | Winlink RMS | Listed in OBRA local planning material as a Winlink FM resource. Confirm current packet or VARA FM settings before operational deployment. | Emergency and public service digital message gateway. |
| W4PCN-10 | OBRA Winlink node | Winlink RMS / packet or VARA FM | Referenced in local ICS-217A communication resource material. Operational settings should match the current RMS Express channel list. | Local Winlink access for ICS forms, welfare traffic, and backup messaging. |
Operating guidance
Repeater access
Program the exact frequency pair, offset, tone or DMR color code, and the approved talkgroup or analog channel name. If you can hear the repeater but cannot access it, check tone or color code first.
DMR access
DMR requires the correct frequency, color code, time slot, and talkgroup. A hotspot working correctly does not prove the same talkgroup is allowed on a repeater.
Winlink RMS
Winlink stations require the correct mode, center frequency or dial frequency, callsign-SSID, and modem setup. Check VARA FM or packet audio levels before an event.
EMCOMM use
For served-agency traffic, use clear message handling, ICS forms where appropriate, tactical calls when assigned, and local net control procedures.
