15  Repeaters are on the Raleigh Carolina 440 UHF Link System  full time covering 14,500 square miles  of mobile coverage.  The present total that can be linked on demand are 32 repeaters covering over 50,000 sq. miles.    

IRLP Node 4270  Used for Emergency Reflector 921 Channel 0   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, group membership or CLICK HERE.  This VoIP technology can also be used with the emergency communications vehicles such as the CISCO, Network Emergency Response Vehicles (NERV).  See a video at this hyper link:  Cisco NERV in Johnston County. 

The UHF Link System also has EchoLink, Node 42704 and it is available to connect with other repeater systems in the US.  The Raleigh System requires a prefix code of 4 #  Then the normal node number all in one stream.  When outbound connections are made, disconnect from IRLP Reflector while using EchoLink and reconnect back to 9210 when done.  International stations are blocked and only United States, Iraq and Afghanistan connections can be made.  If you desire in bound connections to 42704 you will have to be entered into the the EchoLink security database by sending an e-mail to: k4jdr at juno.com. Give the EchoLink callsign and info in your request note. Entering TouchTone® 4 1 1 will give info over the air. 

The Cisco club repeater 444.075+ 100 PL is at RTP on the Cisco Building and can be linked to the Carolina 440 System providing additional technological abilities with Cisco including IPICS technology.
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)® and (EchoLink)®, 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 systems on demand to further extend the link system out of its RF Coverage during emergencies.  There are three systems that can be linked all together via RF, the Coastal Link System Hub repeater is in Clinton. The Down East Link System Hub repeater is located in Kinston.  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 and further extend NC, SC, Va systems with IRLP using Reflector 921 Channel 0.
