Handling traffic in amateur radio means relaying messages from station to station. Before cheap phone calls, this was a way to send messages from one person to another over very long distances. The American Radio Relay League considers this a large part of the ham radio tradition. This skill is still useful for emergency communications.

These relayed messages included a preamble, or the information needed to track the message, and a check, or a count of the number of words or word equivalents in the text portion of the message.
