Training Resources

This information is provided for amateur radio operators (stations) interested in learning more about traffic handling. Along with good on-air practices, you need to understand the radiogram format used when moving traffic, special words that are used during traffic nets, and how to properly log your traffic handling.

While traffic can move over various modes, including digital and Morse code (CW), this information will focus on moving traffic using your voice, such as over single side band (SSB) or FM.

The primary objective of the NTS and the methods and protocols described here is to facilitate transmission of formally written messages from origin to destination so that it arrives exactly as it was written, word for word, letter for letter, space for space, regardless of what mode (voice, CW, digital…) is used. Stations involved in the NTS have a responsibility to promptly relay messages, deliver messages, and service undeliverable messages back. These stations also interface with the public and served agencies, and we expect these stations to represent amateur radio well.

It is highly recommend to listen to a few traffic net sessions to better understand this information before jumping in. You may also want to review the information here in pieces, as trying to comprehend all of it at once can be quite a bit to take on. If you are able to participate in a traffic net that offers training, use the information on this site to help you start off, and seek guidance and feedback from those on the traffic net as you build your skills.
