What is the National Traffic System (NTS)?
Answer: An ARRL-organized network of nets for passing formal written messages across the country
The NTS is a network of local, section, region, and area nets organized by the ARRL to relay formal written traffic (Radiograms) across the country.
What is a Radiogram in the context of the National Traffic System?
Answer: A formatted message with a preamble, address, text, and signature used for formal NTS traffic
A Radiogram is the standardized ARRL message form with numbered preamble, precedence, station of origin, check, address, and text used in the NTS.
What does the precedence 'EMERGENCY' mean on an NTS Radiogram?
Answer: The message has the highest priority and concerns immediate threat to life or property
EMERGENCY precedence indicates a message involving immediate danger to life or property and must be handled and delivered before all other traffic.
What is the 'check' field in an NTS Radiogram?
Answer: The word count of the message text, used to verify accurate copy
The check is the number of words in the message text and lets the receiving operator verify that the complete message text was received without omissions.
Which net type in the NTS hierarchy handles traffic within a single ARRL section?
Answer: Section net
Section nets gather traffic from local nets within an ARRL section and relay outgoing traffic to the region level while distributing incoming traffic to local nets.
What is 'welfare' traffic in emergency communications?
Answer: Messages inquiring about the health and safety of individuals in a disaster area
Welfare traffic conveys information about the health and safety of individuals in or near a disaster area and is typically third-highest in NTS precedence after EMERGENCY and PRIORITY.
