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

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

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.

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

Why should you get involved?

Great public service opportunity Great training opportunity for ARES/RACES Great opportunity to earn wallpaper

Public Service Honor Roll (PSHR) Certificates are available for repeated qualification (12

months straight or 18 months out of 24) See your callsign in QST every month you qualify

Net certificates ORS Appointment STM Appointment

Lots of fun and camaraderie

Many stations begin with number “1” at beginning of each year or month.

Allows easy reference to message in the event of service or delivery problem

Precedence

Indicates importance of message to originator (or served agency)

Provides guidance for Net Operators

Precedence (cont'd)

Four Categories

Emergency: Life or Death – always spelled out!

Priority: Time sensitive – abbreviated “P”

Welfare: Information pertaining to the well being of an individual in a disaster area – abbreviated “W”

Routine: Casual greeting or routine public service message – abbreviated “R”

Handling Instructions (HX) Optionally provide instructions to delivering

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.”

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 preceeded by “ARL”

when ARRL Numbered Radiograms are present in the text

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

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

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)

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.

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

Preamble

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.

The Signature

The name of the individual or agency originating the message.

May include additional data, such as address or telephone number, title, etc.

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

Example of a Routine Message

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

ARL Numbered RadiogramsFSD-3

Routine Message with ARL Numbers

Radiogram Form Record Keeping

REC'D Record callsign, net, date, and time of receipt

SENT Record callsign, 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

Record Keeping Example

Voicing on phone nets It is important that you use prowords 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 proword. Traffic handling is a formal procedure and is not an informal conversation.

NTS MPG has all the details on voicing and prowords. Basic prowords are on the next slide.

Voicing on phone nets (cont'd) Basic prowords

Number Figures I spell Initials Mixed Group Amateur Call Break I say again

Voicing Example

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

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.

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

Delivery (cont'd)

You are representing all Ham Radio operators Make the call Identifying yourself

Non-Hams Hams

The Message Radiogram vs. Telegram

Hardly ever bad news Example: “My name is Nick and I'm a ham radio

operator. I have a radiogram message of greeting for David Smith from Steve Jones in Dallas, Texas. May I please speak with David?”

Reporting

Station Activity Report (SAR)

Mandatory for stations with ORS appointment Appreciated from any station handling traffic Use a log sheet to keep track of your messages Originated,

Received, Sent, & Delivered Public Service Honor Roll (PSHR)

Keep another log sheet with tally of number of net checkins, total time of participation in nets and other public service activities (planned and unplanned)

Report SAR and PSHR totals to STM and SMSTM = Nick Castellano, N2QZ (n2qz@arrl.net)SM = Pete Cecere, N2YJZ (n2yjz@arrl.org)

International Third Party Traffic

You may handle international third party traffic as long as the US has signed an official third-party traffic agreement with that particular country, or the third party is a licensed amateur. http://www.arrl.org/FandES/field/regulations/io/3rdparty.html

The traffic must be noncommercial and of a personal, unimportant nature.

During an emergency, the US State Department will often work out a special temporary agreement with the country involved. But in normal times, never handle traffic without first making sure it is legally permitted.

How can you get involved?

You do not need to make a big time commitment

Start by just checking in to the local nets Casual checkins are OK up to the section level Learn the basic checkin procedures Maybe take some traffic for delivery or originate a

piece Substitute for a missing liaison or NCS Regularly filling one assignment would be a big

help to the system

Getting your Feet Wet

All NTS nets are for training Local VHF nets are specifically intended for training

Do not be afraid to make mistakes. You will receive tips and guidance from more experienced operators, which will help you learn how to do it.

“Anything that's worth doing, is worth doing poorly.” http://www.desktop-meditation.com/new_page_114.htm

Please help!

We need help at every level of NTS from local nets to TCC

Phone operators are needed! CW operators are needed! Digital operators are needed! Personal training is available
