During disasters or other emergencies, radiograms are used to communicate information vital to saving lives and property, or to inquire about the health or welfare of a disaster victim, often called 'health and wlfare trafic'. AND for a anyone affected by or in a disaster area to get the word out to family that they are safe. This is one of the things we are talking about when we say “When All Else Fails” – amateur radio is there! Amateur Radio operators practice these skills every year at field day or even our weekly nets. Remember hearing ‘Does anyone have any formal traffic to deliver or originate via the National Traffic System?’
The NTS was started in 1915 by the newly formed ARRL, as a method of using amateur radio to pass emergency and non-emergnecy messages. The NTS uses a standardized format that maintains accuracy, accountability uniformity and daily nets to pass messages to and from stations around the globe. The NTS uses ALL modes to communicate, Voice, CW, and Digital modes on any band used by amateur radio. Interested in becoming an NTS operator? No restrictions - ANY class of license and have an interest is all thats required.
