National Traffic System

ARRL NTX Section Traffic Manager:
Aaron M Hulett, K8AMH

The National Traffic System (NTS) is a network of amateur radio operators who move information during disasters and other emergencies. General messages offering well wishes also move through the NTS to help test the system and to help amateur radio operators build traffic handling skills. While the NTS is primarily set up to serve the United States and Canada, it is possible to move traffic internationally through the NTS.

When all else fails, there’s amateur radio.

The relay in American Radio Relay League

When areas are hit by large-scale events, such as hurricanes, earthquakes, landslides, or technology failures that impact electricity or communications, amateur radio operators can set up equipment in the affected area to restore communications. Whether that’s by throwing antenna wire into trees, setting up generators, or bringing in a portable repeater, amateur radio allows for communicating across town, across the country, and around the world.

The National Traffic System is an ARRL-sponsored program which provides an organized method for moving messages related to the event. Called traffic, these messages can provide information critical for saving lives or property, as well as inquiring about the health or welfare of those affected. Messages are composed using the radiogram format, and these radiograms are moved, or relayed, into and out of the affected area. This is the Relay in American Radio Relay League: traffic is relayed from one location to another.
