Linking Plans for Interoperable Communications
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
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 KB4FXE, Wilmington AllStar Hub full time.
We also provide support at two of our tower sites, Coats and Archers Lodge with the Johnston County ARES for WinLink. WinLink is a secure wireless e-mail service used in Amateur Radio. See JC ARES web site for details.
SECN and Carolina 440 UHF Link System are a 501 (C3) organization
Any local clubs or special event groups are welcome to use the repeaters at special events located in any of the coverage areas, even if they want to use it partially to eliminate radio traffic on a primary simplex or along with another Repeater that is being used. We can isolate each repeater so that it can be used independently or combined with the ones needed for coverage.
See our SECN Web
Site for our list of charitable organizations that we provide assistance
with our Communications.
If you are from another State or 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.
