The ARRL’s National Traffic System The backbone for ARES messages
National Traffic System Handling Formal Messages ➔ Outline ➢ Formal Messages — what and why ➢ How to format an NTS message ➢ ARRL Radiogram Numbers ➢ Handling Traffic on nets ➢ National Traffic System Structure ➢ Digital Message Handling ➢ Exercise to re-enforce learning Emergency Communications Workshop 2
Formal Written vs. Tactical Messages ➔ ➔ Most emergency traffic is tactical Formal written traffic is important for: ➢ ➢ A record of what has happened — Ability to track Use when relays are required in order to keep messages intact Use of radiogram unless other formats such as ICS-213 or agency formats are required Emergency Communications Workshop 3 3
Third Party Traffic Rules ➔ Permissible Addressees of Third-Party Traffic ➢ ➢ ➢ ➔ U. S. Hams Anyone in the U. S. A. or territories Eligible Station control operators in other countries Anyone in a country with which US has a Third-Party Agreement But not to any country forbidden for 2 -party communications (none at this time) Permissible contents in international radiograms ➢ ➢ ➢ Plain language Of a technical nature or of a personal character Unimportance (non-compete with state PTT’s) Emergency Communications Workshop 4 4

ARRL Numbered Radiograms ➔ Which would you rather send (or receive) at either 13 wpm or reading slow enough to write longhand? ➢ ARL 11 … BT ARL FIFTY ONE Boston's First Night ARL SIXTY New Years Eve or ➢ ➢ ➢ ➔ 37 … BT Greetings by Amateur radio. This message is sent as a free public service by ham radio operators at Boston's First Night. Am having a wonderful time. Wishing you the best of everything on New Year's Eve The “Check” starts with ARL to indicate “ARL 11” for body above (rather than 37) Number is spelled out: “ARL FIFTY ONE” Emergency Communications Workshop 11 11
ARRL Numbered Radiograms (cont. ) ➔ ➔ ➔ ➔ ➔ ARL ONE: Everyone safe here. Please don't worry. ARL TWO: Coming home as soon as possible. ARL THREE: Am in ___________hospital. Receiving excellent care and recovering fine. ARL FOUR: Only slight property damage here. Do not be concerned about disaster reports. ARL SEVEN: Please reply by Amateur Radio through the amateur delivering this message. This is a free public service. [If reply Required, add Handling HXE ] ARL FIFTY SIX: Congratulations on your _____ a most worthy and deserved achievement. * ARL SIXTY FOUR: Arrived safely at _______.

NTS Instructor “Assisted” Exercise ➔ ➔ ➔ Betty M Public wants to send a message to John Q Public on when she will be arriving to meet up with her husband. The text she wants to write is “Arriving 7 PM Dec 24. Looking forward to seeing you soon. Love, Betty M Public” Let’s take a look at how the message header is formatted and how the text affects important items such as the check in the message header and review some of the references discussed in this presentation. Emergency Communications Workshop 14 14
Handling Traffic on Nets ➔ ➔ Follow Net Control Station (NCS) instructions (Simon says) When called to do so: ➢ ➢ ➢ ➔ Check in (with/without) list any traffic you have claim traffic you can deliver give/take (on or off frequency) clear Be precise; Avoid banter; spell as needed but no more, always using ITU phonetics Emergency Communications Workshop 15 15
Pro-Words ➔ ➔ ➔ ➔ Figure – single numeral follows Figures – several numerals follow Letter Group – usually an abbreviation (EOC) Mixed Group – letters and numerals (12 A) Amateur Call – special type of mixed group I Spell – phonetic spelling follows I Say Again – repeat of previous word Emergency Communications Workshop 16 16
Pro-Words (2) ➔ ➔ ➔ Correction – I’m going to correct something End – end of message More – additional message(s) follow No more – no additional messages Say Again – request from recipient to repeat ➢ ➢ ➢ Word after Word before All after All before Between Emergency Communications Workshop 17 17
If Check Doesn’t Match ➔ ➔ ➔ Clarify special items, e. g. , email address is 5 words Read message at reading speed stopping after every 5 words so recipients can identify where count is off or read every fifth word Note discrepancy in count in optional Operator’s Notes Emergency Communications Workshop 18 18
Important Hint Problem: Reading the message too fast when sending is the primary error stations make. If you get many requests for fills or count clarifications, you are speaking too fast. Solution: Physically trace each letter as you send the message. Emergency Communications Workshop 19 19
Radiogram: “Properly Serviced” ➔ ➔ For a message to be “properly serviced” and thus traceable, record how it traveled. This may be in your traffic log or on an actual Radiogram for each message. Received from another station ➢ ➢ ➔ If relaying to another station ➢ ➔ Sent To: Station, date, time relayed If delivering hard-copy to addressee, ➢ ➔ For all messages except those originated, record Received From: Station, date, time received from. Received At: Your call, phone, name address Send Reply to sender or Service message to Originator Emergency Communications Workshop 20 20
IMPORTANT ➔ Goal is to get the message through intact! ➔ From the ARRL NTS Methods and Practices Guidelines – MPG. Do what the trained receiving operator expects and confusion and errors will be minimized Emergency Communications Workshop 21 21
