Public Codes and Auto patch

Public Codes and the Emergency * 911 auto patch on the UHF system is available on the full time Link through all of the participating repeaters.  Other features include a Private Auto Patch and other Private functions by members only.  The system is an open repeater system for use at anytime by any licensed amateur and the auto patch can be used with the assistance of a control operator if one would like to make a call.  The Raleigh, Cary, Durham, Clayton, Coats and Wendell area repeaters can be used for the local phone patch.  Emergency auto patch can be used from any repeater.  We use 100 Hz PL because of occasional interference and to make use of linking functions in the systems engineering. If you are from another area and desire to use the IRLP-VoIP linking while in its coverage area, feel free to contact a Control Operator while here or e-mail in advance to K4JDR  to assist you.

The Public functions include:

          Linking Plans for Interoperable Communications


(Voice Interoperability System for Amateur Radio)

The 441.725+ 100 PL repeater is the Backbone Hub for the UHF Link System, IRLP 4270 and EchoLink 42704, its  controller is what supports the auto patch and other advanced functions for the Carolina 440 Raleigh 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 the RF Link and use the Voice Over IP Link system to further extend repeaters that are out of the RF Coverage areas.   See the repeater list for the frequencies that are on the systems.  For further info on VISAR© go to this URL:  http://www.carolina440.net/VISAR.htm      

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 by using our RF Links and IRLP System via VoIP on Reflector 921 Channel 0  and the AllStar System Node 42235 that we have connected to the KB4FXC, Wilmington AllStar Hub full time.         

The Outer Banks Repeaters will also be part of the Voice Over IP Links.  We will also be experimenting further with the All Star network and with digital systems as well.  We have a Yaesu System Fushion repeater and hope to experiment with DMR radio separate from our RF Linked analog system.   Digital Mobile Radio, DMR information here in NC can be viewed ay:  www.ncprn.net 

We also provide support at two of our tower sites for ARES, Coats and Archers Lodge for WinLink.
