PURPOSE OF THIS MANUAL
Whenever the Authors have attended a class on the NTS, the instructor
managed to "lose" 90% of his students in the first ten minutes. They
simply go into too much detail. The NTS is not a difficult service to
understand. There are, unfortunately, a lot of little details concerning the
Radiogram forms. Most instructors get side-tracked by these details. They drone
on and on about details and their students feel overwhelmed. The students seldom
become involved in the NTS. They have been led to feel that there is too much to
absorb.
We have addressed the need to keep it simple. A definite attempt has been
made to apply the KISS (Keep It Simple, Stupid!) principle to the main text of
this manual.. Some of the manual contents were left in Outline format so that
different concepts and statement relationships can be very clearly understood. A
set of Appendixes furnish the details on various topics . . . not the main text.
The purpose of this manual is to provide a simple teaching tool for you to
use in learning about the National Traffic System (NTS)
PREFACE
by John Freeman, KB8ZDX
The National Traffic System (NTS) seems, to a lot of operators, to be this
big, huge, complex operation that is very difficult to understand. Some of you
may feel that you have to be an Extra with 20 years experience as a Ham to get
involved in NTS because its all done on the HF bands and they use a language . .
. so different that you need 20 years of just listening to understand it. WRONG!!
After going over this material, you will understand that it is not
complicated or difficult to be involved in the NTS. Its' members are operators
just like yourself. You do not have to hold an Extra, Advanced, or
General License. There is a place for everyone in the NTS. These materials are
designed to teach you not only how to get involved, but how to be effective once
you do get involved.
This subject will be broken down simply.As you go through the manual, it
will become more complex only because we put most of the details at the end. If
you start at the beginning and work your way through, you will have absorbed
enough simple background information to make sense out of the rest.
The most important part of the NTS and this manual, is the part that the
authors cannot include.That part is you. This manual means nothing unless you
use it to improve yourself and your operating skills. We welcome the opportunity
to help you do that.
NATIONAL TRAFFIC SYSTEM (NTS) TRAINING
MANUAL
PART ONE
I. What is NTS?
- The NTS is a relay messaging system developed for content accuracy.
Whatever message is sent by way of the NTS, is received exactly as it
was originated. There is no margin for error.
- The National Traffic System consists of ARRL affiliated and independent
amateur radio networks ('nets') which pass non-commercial messages on behalf of
third parties as a public service. That's it in a nutshell.
- NTS has been in operation since 1949. It was established by the ARRL in
response to membership demand. It carries on a tradition of message relaying,
established by Hiram Percy Maxim when he founded the ARRL for the purpose of
handling message traffic in 1914.
II. Traffic - What is it?
- NTS messages are formalized utilizing the "RADIOGRAM" format.
- Once a message has been formalized and entered into the NTS it is called "Traffic".
- Non-formalized messages relayed over Amateur Radio frequencies are not
"traffic" as defined within the NTS.
NTS messages may be sent to, or by, anyone.You do not have to be a ham to
initiate or recieve a message. A licensed ham must, of course, handle the transmission
of the traffic.
III. THE MYSTERIOUS RADIOGRAM

NOTICE!!!
Explanations of this simple form have probably stopped
more people from participating in the NTS than anything else. -- It is just a
piece of paper! -- This is not a confusing IRS tax form! -- It's
simple! -- If you can remember your name and callsign, know what you want to
say, and who you want to send it to, you are already 3/4 done with this form. --
No Mysticism or Rocket Science is involved.
THE FOUR PARTS OF A RADIOGRAM
and the basics of what to do with each one of them. This is dealing with the
very top of the Radiogram form.You should have a copy of the Radiogram in front
of you. This won't make much sense without it.
.
- Preamble
The top part of the form, with all the little boxes, is called the
Preamble. The different parts of the preamble are highlighted below. Look for
the heading on the Radiogram form and read the description for that area.
- Message Number
This is the number assigned by the first Amateur putting the traffic
into NTS. It never changes, no matter how many other operators handle the
message.
- The message has to have a number. If you are originating the
message, you can put any number in this box.What number it is does not matter.
What numbering sequence you use doesn't matter.
- If you are receiving the message, you must use the number
given to you by the sender.
- DON'T say the words "my number 001". DO say "Message
Number Zero, Zero, One". Note: there is no such number as "Ohh".
- Precedence
This tells the importance, or how urgent the traffic is.
- 99% of all traffic is listed as "Routine." Put an "R"
here.
- Don't worry about this right now. There is a more detailed discussion of
this further on in the manual.
- Handling Instructions
This is just an Optional set of specific instructions dealing with
methods of delivery.
- Most of the time, this area is ignored. Don't worry about it!
- We will do some details later on. See Attachment "A" at the end
of this document.
- Station of Origin
This is the Call-Sign of the Amateur who first put the traffic into the
NTS system
- Check
This is a count of the number of words in the text area of the form,
(the area with all the little horizontal lines).
- This does not include anything in the preamble, address and
signature.
- Note: When you use the word "X-Ray" to indicate punctuation,
it counts as a word.When you use the word "Break" it is a courtesy
to the receiving operator and it does not count as a word.
- DON'T say "Check 25, Station of Origin KB8ZDX". It is bad form
to say the headings. DO say "25, KB8ZDX". Please note that
whatever your call is or the proper information received is what will go in
these spots, please do not take "25, KB8ZDX" literally (thanks!).
- Place of Origin
This is the City and State of the party who initiated the
traffic, not the Station of Origin location.
Explained: If you are initiating a message for someone
in Bozoville, Montana and you live in Ohio, then Bozoville, Montana would be the
Place of origin.. Your callsign would be the Station of origin.
- Time Filed
This is the UTC or ZULU time the traffic is placed into NTS system,
not the time written.
- You could have written the message last week. What is important here is the
time you actually put it into the NTS
- .Many NTS operators ignore this field on the form for Routine traffic.
- Date
This is the date the traffic is first placed into NTS system.
- DON'T say "12/4" for date. DO say "December 4".
You do not have to use the year. If the person taking your message
doesn't know what year it is, perhaps you should find someone else?
.
- Address
This is the address of the individual to whom the traffic is supposed to
be delivered. It goes under the word "TO" on the form.
.
- Text
- Keep it all brief and to-the-point
- DON'T say "ARL figure 61". DO say "ARL sixty one".
(More on this "ARL" stuff later.)
- 25 words or less (if possible)
- May contain ARRL Numbered Radiograms (i.e. "ARL One") Attachment "C"
lists all of these
- Use "X-Ray" in place of periods, commas."X-Ray" counts
as a word.
- DON'T send "period" at the end of sentences. DO send "X-Ray"
in place of punctuation.
- DON'T say "End of message" after text. DO say "Break"
after giving the text of the traffic.
.
- Signature
This can be a single name, a name and callsign, or a name and title.
Just enough information to enable the receiver to identify the sender. The
Originating amateur should provide enough information that a reply can be sent.
- DON'T say "Signature or Signed "John". DO say "John".
(NOTE: Amazingly, on the ARRL Form, FSD-244, RADIOGRAM there is no mention
of this fourth part of the form! [It's there ... just in invisible ink] Put it
anywhere you want.)
.
- OK, You are done . . . NOW WHAT?
- Say, "End . . . No More."
That's all there is to filling out a basic NTS Routine message on a
Radiogram form. It really is simple when you don't get bogged down in all the
fine little details right away. Go over this a few times and actually fill out a
blank form while you are doing it.
To get used to how it feels to actually put your voice to it, go to Appendix
"C" where you will find a message all written out. Just read it out
loud several times.
Sending Procedures
- The biggest mistake that all newcomers make is sending too fast. Those
who seem to be aware of this fact go too far in the opposite direction and sendtoo
slow. Listen to the sending pace of the experienced operators and try to
emulate what they do.
- DON'T just keep going from one end of the message to the other. DO
pause between each section to allow the receiver to "Break" if
necessary for fills. (A "fill" means a repeat of a certain
section.) DO send it clearly and slowly, but not dragging it out. Practice
writing your own message down as you send it. This will give you an idea how
fast you can reasonably expect someone else to copy it down.
- How a "Fill" works. If a receiving operator misses
copying part of a message, he/she can request that you repeat part of it by
breaking back to you during one of your pauses and saying, "Break....fill
from [last word of a string that he got ] to [the next word that he got]".
Just back up and give him the part he missed by saying "Fill . . . [give
him what he missed] pauseand go on with your message.
When and Where to send a "Radiogram"
- Local Traffic (In-town/county), send it:
- During a Net on your local repeater
- Anytime on the repeater or via local telephone
- Out of town or county traffic
- During any Net on your local repeater ask for a station who may take "traffic"
for the area it needs to go into.
- Check with your Local Net Manager or Emergency Coordinator for stations who
take relays oftraffic for other areas and countys.
- Long distances within same state
- During a Net on your local repeater, see if there are any relay stations to
the HF Nets operating within the state that can pass to a "Higher Net"
- If you have the privileges, check in to one of the state wide nets and pass
traffic to a station who is local to the intended receiver
- Check with your Local Net Manager or Emergency Coordinator to find who is
the Local Liaison for HF Nets if you do not have the privileges or the
equipment. (A Liason is an operator who has agreed to help pass NTS traffic for
others.)
- Out of State or Country
- Pass it to an NTS Net that you have the privileges for
- Pass your traffic to the Local Liaison via repeater or telephone
- If the message is going out of the Country, check to ensure that the US has
a third party agreement with the country it is going to. If not sure, check
with your Emergency Coordinator or your local Net liaison.
IV. METHODS OF PASSING "TRAFFIC"
RADIOGRAMS may be passed via any means available to an Amateur Radio
Operator . . .voice, phone. Repeaters, simplex, VHF, UHF, HF, as long as you
have the privileges to operate on a frequency, you can pass messages there.You
may use:
- Phone (Voice) anywhere it is legal for you
to operate.
- CW. NTS messages can be passed using CW on VHF, UHF, HF, any frequency
that the operator is authorized to use
- Packet. VHF and HF are the most common.
Packet can be the ideal means of passing formalized message traffic in certain
circumstances. It is especially useful when a "secure" method is
necessary to safeguard the privacy of disaster victims. It is also very handy
whenever a "hard copy" is needed for record keeping.
Packet BBSs provide a looser structure for getting messages from the sender
to the area of destination. This looseness has its advantages and disadvantages.
An advantage is that participants can have more flexible schedules - one does
not have to set aside a specific time for a regularly scheduled net. A
disadvantage is that the sender, does not know if there is a human-receiver on
the other end that will deliver the message. For the system to work efficiently,
each BBS should have someone (or some group) responsible for delivering NTS
messages.
- RTTY/AMTOR. HF is the most common.
Another digital mode(s) available for passing of traffic
Traffic NetsThere are specific times, days
of the week and a variety of frequencies available for formal "Traffic Nets".
Check with your local Net Manager, Emergency Coordinator or Net Liaison to find
out when and where they meet. The ARRL Net Directory is a good source of
information. We have also included several Appendices at the end of this manual
which are lists of various nets at different levels.
During a Club Net, ARES Net, District Net, etc. is the perfect time to pass
some traffic, even if just for practice. You can usually locate someone who
will receive the traffic and will also work with you on your technique.
Don't worry about getting everything perfect. Practice makes us all better.
If you listen to an NTS net for ten minutes, you will hear some of the
old-timers make some blunders. It's no big deal! The most important part is to
listen to how the traffic is handled and passed, then practice what you know is
correct out of what you hear. People who are involved in the NTS nets welcome
newcomers. Just tell them you are new to the system and they will coach you. Of
course, there is always the net "Grump". Don't worry about him.
If you never learn any more than this about the
Radiogram, you will do just fine passing traffic in the NTS with what you have
learned so far. By the time you compose and send 10 or 12 messages, the
Radiogram form, these simple procedures, and what to say, will be permanently
imprinted on your brain.
We will now go into a little more depth and examine some of the finer
points.
IV. SOME MORE ADVANCED STUFF
THE NTS STRUCTURE - How it works
Reminder: The NTS is made up of several associated, yet totally separate
Nets held on various levels.
- Local Nets. This is the Lowest level NTS
Net.These Nets usually meet on local repeaters and are the first level of the
NTS system. This is where traffic will be passed between cities, counties and
sometimes within Districts or multi county areas. If the traffic needs to go any
further or to the next step, it may be passed on to an operator who will take it
to the next level Net, the Section Net.
- Handling of Local MessagesThese are usually
within your own county, city or within reach of your local repeater. If you
receive the message, follow the delivery instructions to the party intended. If
it is out of your area for phone delivery or you are the originating Amateur,
try to find a station on the repeater who can deliver the message and send the
traffic to that station. You will find repeaters to be excellent resources for
passing NTS traffic locally. Try during a Club Net or an ARES/RACES Net on the
repeater if there is not an official NTS Traffic Net held on your local
repeater, this is usually an excellent time to catch someone in the area where
the traffic needs to go.
- Section Nets. A Section is an area
designated by the ARRL (Amateur Radio Relay League). Each Section will have a,
or several, NTS Nets established for the purpose of transferring this traffic or
messages. This traffic is normally stays within that Section and is received by
stations in the area where it is intended to go. If the message is to go to the
next level Net, it is usually received by a designated operator to relay to the
Region Nets.
- Handling of Section MessagesThese are to be
delivered within the ARRL designated Section. This usually means that the best
way of delivering it would be to go to one of the Section/State NTS Traffic Nets
that are in place. These are found on HF usually, but a few are found on wide
coverage repeaters. If you do not have the ability or privileges to transmit the
traffic yourself to the HF Net, ask your Emergency Coordinator who the NTS
liaison is within your county and deliver the traffic to that operator for relay
to the Section Net.
- Region Nets . These Nets cover a much
larger area. A representative from each section takes the messages to this Net
that are intended for parties outside of the Section but within the Region.
Traffic intended for parties outside of the Region will be passed on to
operators designated to take them to the next level Net which is the Area Net.
- Handling of Region MessagesThese are
intended for a party within an ARRL designated Region The traffic will usually
start off in a Section Net and be transmitted to the Region Net by the operator
with that responsibility. Follow the same procedures as the Section Messages.
- Area Nets. This is the top level Net of
the NTS.It covers the available world. Representatives from each Region will
bring traffic to these Nets to be passed around the designated Area or into
other Areas. Each of these Nets has one basic item in common; each will have an
appointed Manager to oversee the operation of each level. These will all be
covered in greater detail later in this material
- Handling of Area MessagesThese are intended
for a party within one of the designated ARRL Areas. Normally it will be passed
from Local to Section to Region to Area Net until it gets delivered to the
intended party, regardless of where they are. The procedure on your end is the
same, you introduce the traffic by the best means you have available. If you can
take it to the Section Net, do so yourself. If you do not have the privileges,
utilize the procedures drawn out above for the other Nets.
- Handling of Out-of-U.S. (Country) Traffic.
Remember to verify that the U.S. and the receiving country have a Third Party
Agreement. A Third Party Agreement means that the U.S. and the other country
have a legal agreement allowing U.S. Amateurs to pass traffic into that country.
Another Simplified Summary of the NTS
Structure
To make sure that you understand this structure, we are going to explain it
another way. The United States and Canada are divided into three Areas: Eastern
Area, Central Area, and Western Area. Inside each of those three Areas there are
a total of twelve smaller Regions. Inside each of those Regions is an unknown
number of Locales.
Picture in your mind, two funnels ... with the big ends put together.These
two funnels now represent the NTS System. The flow of traffic is always from one
of the small ends to the other small end. The small ends are the Local Nets.
Your message may rattle around in the funnel assembly for a while, but with
enought movement it will eventually reach the other small end.
HOT TIP: If you are sending a message
out-of-state or country, when you list your traffic with a net, list it as:"One...
through ...for [ State of destination].If someone is on the net who can
skip one or more of the normal steps of progression, they will pick up your
message and get it through quicker. This just cuts out a number of "middle
men".
