The
UHF repeaters are used for local SKYWARN
Administration and if the need arises
for any emergencies related to
SKYWARN and ARES. The
Carolina 440 UHF Link System is designated for
Local and Coastal SKYWARN Administration. The Coastal Link System
could be activated if the need arises during severe weather to
exchange useful information from the coastal areas surrounding Wilmington,
Castle Hayne, Holly Ridge and Topsail Island to the National Weather Service offices
including passing information to the NWS here in Raleigh, N.C.
The IRLP Link System provides
additional linking capabilities for other agencies such as the National
Hurricane Center in Miami, FL. during severe weather across the Nation.
The 146.775 VHF System is also our dedicated system that is used for the VoIP Skywarn
Net activities with our
Raleigh Reflector 921 each Saturday night at 00:00 UTC Sometimes we
will link the UHF system to it during special activities. The VoIP
Weather Net site can be viewed at: http://www.voipwx.net
The VoIP SKYWARN / HURRICANE NET
is held each Saturday night on Reflector 9210 sub-channel 9 at 00:00 UTC, 19:00 Hrs
EST and 20:00 hrs EDT. This means 7:00 PM Winter, 8:00 PM Summer US
Eastern Time. See www.timeanddate.com/worldclock/
for world time. You can view more information on IRLP by clicking on the links to the
right under IRLP Info and EchoLink.
On October 3, 2002 Hurricane Lili
was the first IRLP -
Hurricane/Skywarn net. using
our
East Coast Reflector 9210 in
Raleigh, N.C.

Public Codes and
Auto patch
Public Codes and the *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 membership 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:
Emergency
Auto patch ( * 9 1 1
) Raleigh 911, transfers emergency calls to other Cities and Counties in
the coverage areas including the NC State Highway Patrol.
Time ( 5 6 )
Time and Temp ( * 4 5 6 )
90 second Weather Broadcast ( * 4 5 )
A signal meter check can be done into the 441.725 Hub Repeater as well if you are in its coverage area, the code is: S- Meter ( * 3 2 ) Other repeaters on the link when entering this code will give you the link radios signal report into the Hub only.

EAR 5120
SAME Weather Radio Alerts (Raleigh System)
There is a MTS, EAR-5120 NOAA Weather Radio receiver interfaced into the UHF Hub repeater system operating on 162.450 Mhz. The 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, and if 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 the 162.450 mhz on the MTS receiver activates during selected warnings in the following four Counties in
RED and the Garner transmitter covers the remaining Counties also and they are:
Franklin,
Harnett, Johnston, Nash,
Wake, Wayne and Wilson
Counties. Additional service areas are
Durham, Granville, Person
and Vance.

Linking System at the Outer Banks
We also have a telephone interconnect link to the Outer Banks of North Carolina. This system is operated for now by the Control Operators Only of the repeaters. The UHF Hub repeater can be linked to the Buxton, K4OBX, 145.150 PL 131.8 running 70 watts at 200' . It is linked full time to a bunch of 15 watt "hotel" repeaters stashed all over the place. (usually at NCEMC Substations....) 444.825 PL 131.8 South Nags Head 300' covers all of upper Dare County beaches, Roanoke Island and Mainland Dare. 444.325 PL 131.8 on a 40 ft pole in the Rodanthe CHEMC Substation covers the Tri Villages of Rodanthe, Waves and Salvo and goes about half way to Avon. A remote receiver on 444.725 PL 131.8 gets you from a 45' antenna in Avon and takes you down to Buxton and Frisco. 444.725 PL 203.5 on a 100' tower at the Hatteras Fire Department takes you from Frisco right through the North end of Ocracoke. 444.225 PL 131.8 at the Tideland Electric Generator in Ocracoke Village, on a 45' pole takes care of Ocracoke right on through Portsmouth Island. You can take a 1/2 watt HT on UHF and get on the system from anywhere you might bike or camp or play within the entire Cape Hatteras National Seashore. Likewise you can use that same low power to be at any of the food kitchens and shelters in any village or emergency vehicles, etc. It works great in Hurricanes.......... each of the remote sites has enough battery for about a few days since most of them are powered by the electric company back-up systems.
We also have a Interconnect Link ability to the 444.925+ 131.8, K4OBX Repeater on Hatteras Island. Control Operators are only capable to establish these links for now. We use this to get weather reports from Spotters in the coverage area and use it to occasionally call someone and test the system.
The Outer Banks has IRLP linking as well. IRLP Node 8270 in Buxton, NC 146.625 -131.8 PL

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 and 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 demand to further extend the link system out of RF Coverage. We have three systems all together, the Down East Link System Hub repeater is located in Kinston and the Coastal Link System repeater is in Clinton. See the repeater list for the frequencies that will be on the system. 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 Hub from the Down East and Coastal repeaters. The Outer Banks Repeaters will also be part of the Voice Over IP Link in addition to the Telephone Interconnect and possibly a RF Link. Click HERE to read the history of our repeater projects.
We presently have IRLP on the 146.775- 88.5 PL, KD4RAA Repeater in Raleigh. It is connected to a high volume IRLP Reflector at times for the enjoyment of Hams to discover this new technology. See additional info on the IRLP at http://www.irlp.net and look over our Raleigh IRLP URL. The two meter repeater can be linked into the UHF Link System by Voice OverIP. We have an East Coast Reflector Node 921 also and will use it internally when we have emergencies and need to Link all of the repeaters here in NC into the network using sub-channel 1. Its intent was to be an EMERGENCY REFLECTOR See additional info and user guide here or click on the "Linking Network" on the home page.
Our YAHOO User Group site has a lot of pictures and technical files, you will have to sign into Yahoo with a user password and you do not have to be a member of our Repeater Group to view these pages.
Membership Donations
Anyone wishing to use the Private features of the repeaters are asked to
contribute for Full Membership at $25.00 per year to go to the telephone
interconnect and equipment fund and will be given an auto-dial slot with a
private user code list including IRLP Link Codes. More Info with an
on-line application for a Contributing Member with support fees can be
viewed at: www.kd4raa.net
on the bottom of the page.
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 another Repeater that is being used. *911 Emergency auto patch is available at any time.
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.
