The IRLP and EchoLink System provides
additional linking capabilities for other agencies such as the National
Hurricane Center in Miami, FL. during severe weather across the Nation.
The KD4RAA, 146.775 VHF System is also a dedicated system that is used for the VoIP Skywarn
on IRLP Raleigh Reflector 9219. The VoIP

is a MTS, EAR-5120 NOAA Weather Radio
receiver interfaced into the UHF Hub repeater system operating on 162.450 Mhz.
NOAA transmitter is located in Auburn, N.C.
between Garner and Clayton on the WRAL-TV
Tower and is considered the Garner weather transmitter.
It has an ERP of 920 Watts and its
antenna pattern is directed to the
southeast toward Goldsboro.
It can be accessed on the UHF link system by a public user code to hear
a 90 second weather broadcast by entering touch tone * 4 5. When
the weather receiver is monitoring in the muted alert mode,
a signal is lost over ten
seconds on the receivers primary channel (162.450 Channel 3), a secondary Channel will be switched to (162.550 Channel
7), This transmitter is located near Chapel Hill,
N.C. on the WUNC-TV Tower.
This can be reset remotely by a member of the user group when the primary channel is back on the air.
The weather receiver is
made by MTS in
Clayton, N.C. and it has SAME
(Specific Area Message
Encoding) technology and
162.450 mhz on the MTS receiver activates
warnings in the following four Counties in RED and
the Garner transmitter covers the remaining Counties also and they are:
Harnett, Johnston, Nash,
Wake, Wayne and Wilson
SAME Warnings are:
Shearon-Harris Alert, Radiological Hazard,
Danger, Missing Child

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
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 . The Charlotte Metrolina areas Hospital Emergency Amateur Radio System (NC HEARS) will have the ability to link as well using EchoLink. To 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 Links. We will also be experimenting with All Star network and be experimenting 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, 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.
