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. There are three systems that can be connected all together, the Coastal Link System repeater is in Clinton and can be linked on demand and the Down East Link System repeater is located in Kinston and usually is connected to the Coastal System. 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.
The W4SNA Winston Salem Link System is linked through our VoIP on Reflector 921
Channel 0 every day at 0800 hrs to 2200 hrs except for the Good Morning net at
1000 hrs for approximately 1 hour Monday thru Saturday, and Friday nights during
a net at 2130 hrs. The Charlotte Metrolina areas Hospital Emergency Amateur Radio System (NC HEARS) is
also under construction and will have the ability to link as well using RF and
see more on the NC HEARS go to the web at: www.nchears.org
The Outer Banks Repeaters will also be part of the Voice Over IP
Any local clubs 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
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.
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.
