Colorado Traffic Net

About the Colorado Traffic Net

The Colorado Traffic Net (CTN) is a directed VHF net that meets every evening between 7:00 and 7:25 PM local mountain time to handle formal National Traffic System (NTS) messages called “traffic” into, out of, and within the State of Colorado.

The NTS is an organized network of amateur radio operators for the purpose of relaying messages. The NTS is most useful during emergencies when telecommunications infrastructure such as cell phone and land line telephone are inoperative. The CTN is an officially recognized NTS net which is sponsored by The American Radio Relay League (ARRL).

Handling traffic efficiently and accurately requires practice. Therefore, the NTS commonly practices with routine messages such as greetings, congratulations, and license renewal reminders in order to hone the skills of its operators. We welcome and invite anyone and everyone to be involved!
