Saguaro National
Traffic System (NTS)
Nightly Net

SAGUARO NTS NIGHTLY NET:
The Saguaro NTS Net meets EVERY NIGHT on ham radio at 6:30 P.M. (1830 hrs MST). Due to issues with the EAARS Mt. Lemmon repeater, on June 1, 2020, the net moved to N7OEM at 146.880 with a PL Tone of 110.9 (Pima County OEM COMM). If the 146.88 is being used at NET time, we will move to 145.250, PL Tone of 156.7. Join us and learn and participate in NTS messaging. Training tidbits are offered nightly and we are happy to help. Our purpose is to relay radiogram message traffic within the United States (and outside the U.S. wherever Third Party Traffic is permitted). The Saguaro NTS Net meets to enable hams with any level of amateur radio license to participate.

WHAT IS THE NATIONAL TRAFFIC SYSTEM?
The National Traffic System of messaging began over 100 years ago with the formation of the American Radio Relay League in 1915, a proud tradition that continues today. Our intention is for this site to be a helpful resource to all ham radio operators interested in handling message traffic.

WHAT IS A RADIOGRAM MESSAGE?
Radiogram messages are the heart of the National Traffic System (NTS). Remember the telegraph messages of old? Radiogram messages are 25 words or less, and range from birthday and holiday greetings to simple messages to keep in touch. These messages can go to anyone, whether or not they are a ham (amateur radio operator). Radiogram messages are relayed on radio nets and sent digitally by hams all over the United States and can be sent to other countries (wherever Third Party Traffic is permitted). In times of an emergency, hams handle Health & Welfare message traffic to and from disaster areas.

ARIZONA TRAFFIC & EMERGENCY NET (ATEN):
The Saguaro NTS Net is an affiliate of the Arizona Traffic & Emergency Net (ATEN), an HF voice net which meets nightly on 3986 kHz (80 meters) at 5:30 P.M. (MST) as of October 15. Saguaro NTS members relay traffic to and from the ATEN, and also connect with other wide-area HF nets. Saguaro participants also utilize CW, Pactor and other modes to relay traffic into and out of Arizona.

SAGUARO NTS NET HISTORY:
Max, KI7TIG, is net manager since April 2019. Past net managers include: Byron, AA7BM; Pink, K7ILA; Bill, KC7ZZ; and Greg, W9GRG (former KC5ZGG). Pink, K7ILA, and Bill, KC7ZZ, started the Saguaro NTS Net in June 2009 during Field Day (a national ham radio weekend). Many thanks to the Radio Society of Tucson (Randy, KF0X, in particular) for encouraging us to start the net on the K7RST repeater atop Mt. Lemmon. We moved to the EAARS network in 2010 to reach a wider geographic area. Due to issues with the EAARS repeater on Mt. Lemmon, the net moved to N7OEM on June 1, 2020. Alternate is -145.250 (156.7).
