2. What is the National Traffic System? The National Traffic System or NTS is a system that organizes Amateur Radio Operators for the purpose of providing timely and reliable movement of third-party message traffic from origin to destination as a free public service to the amateur community and the general public Our goals are efficiency and accuracy

3. Goal 1: Efficiency Efficient net operation Participants Maintain proper net discipline Proper pace for radiogram transmission Conditions Ability of the receiving station (know your stations!)‏ NCS Sending stations off frequency to move traffic in parallel (know your stations!)‏ Prioritizing traffic based on quantity

4. Goal 2: Accuracy Never change a message in transit for any reason! If you feel that corrections are necessary, add an op note instead. Follow proper net procedure, and use proper voicing techniques to help ensure accurate copy.

5. History of the National Traffic System The National Traffic system (NTS) has its roots in the earliest days of Amateur Radio The American Radio Relay League (ARRL) was founded in 1914 by Hiram Percy Maxim to facilitate the relay of radiogram message traffic The ARRL organized amateurs as Official Relay Stations The ORS appointment still used today in the ARRL Field Organization

22. Station of Origin Call sign of first station to place message on air Example: If W8ZZ calls W8IHX on the phone and asks the later to originate the message, the Station of Origin is “W8IHX.”

24. Check The number of words or groups in the text Does not include address or signature Mixed groups, such as “6TH” or “FSD212” count as one word The “X-ray” (“X”), used in place of a period, counts as one word The word count is preceded by “ARL” when ARRL Numbered Radiograms are present in the text Telephone numbers with area code count as 3 words

26. Place of Origin This is the location of the individual whose name appears in the “Signature” portion of the message It is not the location of the station that places the message on-air

28. Time Filed Four figure time group in UTC (GMT)‏ Example: 2330Z Never use local time Indicates the time the message was drafted or the time the event occurred This is optional

30. Date Filed Always expressed as a three-letter month and day Examples: “JUN 10” or “JUL 4” Always read on phone as full month name Examples “June One Zero” or “July Four” Must reflect date in UTC (e.g. new day starts at 7 PM EST or 8 PM EDT)‏

32. Address Should be as complete as possible Include telephone number In some cases, it may be abbreviated When an agency has a direct liaison on air: “NWS-DTX” for National Weather Service “MSP-EMD” for Michigan State Police EOC When addressed to a radio amateur active on a net e.g. WC8EOC for State E.O.C.

34. The portion of the message containing the preceding service information is called the Preamble

35. The Text Try to limit to 25 words or less for routine messages Keep as brief as possible for official traffic Avoid difficult or confusing language Utilize the “X” for a period. Never end a radiogram text with an X Always convert the “X” to a period when delivering traffic in writing.

37. The Signature The name of the individual or agency originating the message. May include additional data, such as address or telephone number, title, etc.

39. Op Note Conveys additional information to relay or delivery stations Two kinds of op notes Address op note, after name /address / phone number Signature op note, after the signature

40. Example of a Routine Message

41. ARL Texts Common message texts designated by a code to speed transmission of traffic Example: ARL One = “Everyone safe here please don’t worry” ARL numbers are always spelled out

42. Routine Message with ARL Numbers

43. Radiogram Form Record Keeping REC'D Record call sign, net, date, and time of receipt SENT Record call sign, net, date, and time of relay THIS RADIO MESSAGE WAS RECEIVED AT Record your contact information when providing paper delivery by US Mail or by hand

44. Record Keeping Example

45. Voicing on phone nets It is important that you use pro-words properly to ensure correct copy Once you begin transmitting a message, every word you say should be either part of the written message or a pro-word. Traffic handling is a formal procedure and is not an informal conversation. NTS MPG has all the details on voicing and pro-words. Basic pro-words are on the next slide.

46. Voicing on phone nets (cont'd)‏ Basic pro-words Number Figures I spell Initials Mixed Group Amateur Call Break I say again

47. Voicing Example

48. Book Traffic Groups together messages with similar contents for convenience Eliminates the need to repeat the same information multiple times “Basic Book” has the same text for every message in the book, with varying message numbers and recipients Other permutations are less common but are perfectly legitimate

49. Net Operations NTS Traffic nets are formal, directed nets. The Net Control Station is in charge. Be sure to follow instructions from NCS accurately to the best of your ability.

50. Delivery Confirmed delivery (preferred)‏ Telephone By hand Unconfirmed delivery Voice mail or answering machine U.S. Mail Service originating station if they requested confirmation, or if delivery was unsuccessful or unconfirmed
