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 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 repeaters by RF Link and use the Voice Over IP Link on the Raleigh IRLP Reflector 921 Channel 0 for multiple connections.  This will further extend the link system out of the RF Coverage. 

This VoIP technology can also be used with the emergency communications vehicles such as the CISCO, Network Emergency Response Vehicles (NERV).  We have three systems that can be linked all together, the Raleigh System has the backbone hub for RF Linking and VoIP network.  The Down East Link System Hub repeater is located in Kinston and the Coastal Link System repeater is in Clinton.  These two will have to be enabled on demand to Raleigh by a touch tone user code.  See the repeater list for the frequencies that will be on the system. Also for the VoIP (IRLP) linkable repeaters list go to:  http://status.irlp.net/IRLPstatus.php?option=2  

EchoLink Node# 42704 is also used on the system for VoIP connections.  EchoLink is used by the Incident Communications Systems (ICS) Mobile Command Vehicles to connect to Amateur Radio Stations in the area or in the field with on board radios and wireless communications using VoIP technology.  See more info on ICS at this web site: http://www.incidentcommunications.com/

This Carolina 440 UHF Link System would not be possible if it were not for our generous benefactors for Tower Space.
