Repeaters on Link

9 Repeaters are on the Raleigh Carolina 440 UHF Link System full time covering 6,160 square miles of mobile coverage. The present total that can be linked on demand are 21 repeaters covering 21,168 sq. miles.

IRLP Node 4270, Used for Emergency Reflector 921 Channel 7   for local linking to repeaters outside the RF coverage. Point to Point IRLP Linking can also be done; user access codes can be requested from repeater trustees or group membership. This VoIP technology can also be used with the emergency communications vehicles such as the CISCO, Network Emergency Response Vehicles (NERV). See also video at this hyper link: Cisco NERV in Johnston County.

The Cisco club repeater 444.075+ 100 PL is at RTP on the Cisco Building and on the Carolina 440 Link System providing additional technological abilities with Cisco.

The repeaters are also used for local and regional Emergency Communications involving
State ARES , NWS / SKYWARN programs , (Community Emergency Response Team) CERT programs and Amateurs in the Public Safety Sector of NC CERT (Canine Emergency Response Team) and NC USAR (Urban Search and Rescue) Task Force 8 Communications Group.

The Emergency auto patch * 911 is available to Raleigh 911 from all local RF systems. The local area auto patch is available through user group membership in the Raleigh system.

Carolina 440 Linking Plans for Interoperable Communications

( Voice Interoperability System for Amateur Radio )

The 441.725+ 100 PL repeater is the Backbone Hub for the Carolina 440 UHF Link System and Emergency
VoIP system (IRLP), its controller is what supports the auto patch and other advanced functions
for the Carolina 440 Link System. This system is what we call our Voice Interoperability System for
Amateur Radio, VISAR. We have provided a list of the "Repeaters on the Link" with their geographical
location to guide you on what repeater would be best for you, based on your location. The future plans
are to link several more UHF repeaters by RF Link and use the Voice Over IP Link on demand to further
extend the link system out of RF Coverage during emergencies. We will be linking three systems all
together in the future, the Down East Link System Hub repeater is located in Kinston and the Coastal Link
System Hub repeater is in Clinton. See the repeater list for the frequencies that will be on the system.

Experimentation on other UHF linking possibilities will take place and it is subject to change. We
are going to try and cover as much as we can to the Raleigh Backbone Hub from the Down East
and Coastal Hub repeaters.

Our YAHOO User Group site has a lot of pictures and technical files, you will have to sign into Yahoo
with a user password and you do not have to be a member of our Repeater Group to view these pages.
