The National Traffic System (NTS) is an organized network of amateur radio operators sponsored by the American Radio Relay League for the purpose of relaying messages throughout the US. During normal times, these messages are routine greetings ("Happy birthday Aunt Mary") and keep the system well oiled and the operators trained so that everything works when needed. When there is an emergency or disaster NTS works closely with the Amateur Radio Emergency Service to provide emergency communications. The most common type of disaster-related messages are "health and welfare" inquiries and notifications into and out of the area affected by the disaster. In time of disaster, it is easy to expand the system by simply creating additional meeting times for the nets with high volume, or by setting up a specific "trunk line" between two points. The National Traffic System (NTS) is a structure that allows for rapid movement of traffic from origin to destination and training amateur operators to handle written traffic and participate in directed nets. These two objectives, which sometimes conflict with each other, are the underlying foundations of the NTS. NTS operates daily, even continuously with advanced digital links. The personnel consists of operators who participate for one or two periods a week, and some who are active daily. The National Traffic System is an organized effort to handle traffic in accordance with a plan which is easily understood, and employs modern methods of network traffic handling in general acceptance today. NTS is not intended as a deterrent or competition for the many independently-organized traffic networks. When necessitated by overload or lack of outlet for traffic, the facilities of such networks can function as alternate traffic routings where this is indicated in the best interest of efficient message relay and/or delivery. One of the most important features of NTS is the system concept. No NTS net is an independent entity which can conduct its activities without concern for or consideration of other NTS nets. Each net performs its function and only its function in the overall organization. If nets fail to perform their functions or perform functions intended for other nets, the overall system may be adversely affected. NTS is defined using geographic areas. The US is divided into areas that approximate time zones. Areas are divided into regions, and regions into sections that correspond to a state. Each of these subdivisions has nets for collecting and distributing traffic. A net is nothing more than a time of day and a radio frequency where the appropriate group of amateur operators can meet to send the messages on their way. The process of traffic passing is best explained by an example. Let's say that someone in Minnesota wants to send a birthday greeting to Aunt Mary in California. They telephone their local ham friend and give him the message.
Perhaps this sounds rather complex, but it really isn't. Each net uses the same procedure and operating techniques, so as novice operators gain experience they can "graduate" from section to region to area nets. Every message is placed into the same format. The operation is disciplined but not unduly complex. In times of great emergency or disaster this has been proven time and again the best way to handle the task of reliable message handling. Kentucky NTS Information
