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 systems including (IRLP)®, AllStar® 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 special events and disaster emergencies.  

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 our VoIP systems and IRLP using Reflector 921 Channel 0.  We will also be experimenting with Yaesu System Fushion and other projects with DMR Radio.   DMR Website is:  www.ncprn.net 

New Linking systems to Wilmington area is being developed to support the I-40 corridor between Raleigh and Wilmington areas.
