TARC: Wide-Area Link System

This repeater system is a stable platform to be used in times of emergencies by Amateur Radio Operators. It is designed to support the same area that the National Weather Service and Salvation Army cover. At this time, the system covers about 50,000 square miles of eastern Oklahoma, the southern edge of Kansas and western Arkansas; The central hub repeater is in Tulsa. The system extends to the north and east, to Bartlesville and Ketchum and Decatur, AR. To the west the system has repeaters in Mannford, Ponca City, Stillwater and North Edmond. To the south and east there are repeaters at Mounds, Muskogee, Tahlequah, Cavenal Mountain near Poteau, Fort Smith, AR, McAlester, Blu Mountain near Enterprise and Daisy OK.

The TARC manages and controls the system from the gateway repeater in east Tulsa on 443.850 Mhz. In Tulsa, this repeater system can link with two VHF repeaters for local Nets. The systems primary use is for Weather Nets and wide area community support. A complete list of all the linked repeaters and their current status follows.

The system is open for use to all Amateur Operators at all times except during controlled nets, when traffic is directed through the Control Operator(s). TARC reserves the right to control this system and all systems linked to it.


PLEASE, NO LINKING OR VHF CROSSBAND LINKS TO THE UHF SYSTEM!

The use of base station, mobile radios or other systems, including Internet linking through nodes, EchoLink, IRLP etc, is NOT generally allowed on the UHF linked system. Prior consent of the Master Control Operator and club officers is required to do this. We need to have contact information for the appropriate people in order to have interfering signals better managed should such systems create problems.

Because there are so many repeaters involved, any potential interfering system, needs to be managed by a control operator who can disable it if needed.

Special events with EchoLink and other inter-working technologies can be allowed, we just need to have knowledge of such events/stations so that proper care of the system is possible.

It is strictly necessary to enforce the above restriction. During emergencies and general operation of the link system and the outlying repeater systems that are operated by other clubs and officers, they need to be able to use their equipment. These added systems must meet TARC’s Technical Standards to be allowed on the system. The reason for these requirements is to uphold the integrity of the system. Please contact Gregg Wonderly for Equipment and or Standards.

 


This system has been proven to work well with a 30-watt mobile radio and dual band 5/8 wave antenna. The rolling terrain in NE Oklahoma can create some fading of signal strength. Home stations have greater access to the system with taller antennas.

We would like to take this opportunity to give “a big thanks” to KJRH(channel 2) and KTUL (channel 8) for tower space to place our link system antennas.

If you or your club would like to link into the system, and/or your area is in a strategic location to provide beneficial coverage, please contact us for more information. Additional financial support for this project is also being sought to help expand the coverage area.
