INTRODUCTION TO PACKET RADIO - PART 12 - by Larry Kenney, WB9LOZ

The National Traffic System, known as NTS, is the ARRL sponsored Amateur
Radio message handling network.  Packet radio is now playing a very
important part in the network, so let's take a look at the system and
give you some tips on handling NTS traffic by packet.

Handling third party traffic is the oldest tradition in amateur radio.
Nationwide, the National Traffic System has hundreds of local and section
nets meeting daily in order to facilitate the delivery and origination of
such messages.  More and more of this traffic is being originated, relayed,
and delivered on packet.  If you enjoy traffic handling, you can easily get
involved in NTS via packet.  If you're on packet but know nothing about
NTS, this part of the series will get you off to a good start.  At the end
you'll also find some references for further information on NTS.

Local packet BBSs have to be checked daily for traffic that needs to be
delivered or relayed.  When you check into your local BBS, enter the LT
command, meaning "List Traffic".  The BBS will sort and display a list of
all NTS traffic awaiting delivery.  It'll look similar to this example:

 MSG# STAT SIZE TO     FROM   @BBS   DATE/TIME SUBJECT
 7893 T     486 60625  KB6ZYZ NTSIL  1227/0712 QTC1 CHICAGO, IL 312-267
 7802 T     320 06234  K6TP   NTSCT  1227/0655 QTC1 NEW HAVEN, CT
 7854 T     588 93432  KA4YEA        1227/0625 QTC1 CRESTON, CA 93432
 7839 T     412 94114  KK3K          1227/0311 QTC1 SAN FRANCISCO 415-821
 7781 T     298 94015  W1KPL         1226/2356 QTC1 DALY CITY, CA 415-992

You might see traffic that is being relayed by your local BBS to some other
part of the country as well as traffic for your local area. The "Subject"
or "Title" column of the listing will show the destination of the traffic.
If you see a message that is within your local area, help out and deliver
it.

RECEIVING A MESSAGE: To take a message off of the Bulletin Board for
telephone delivery, or for relay to a local NTS net, enter R followed by
the message number.  Using the list above, R 7839 would send you the
message from KK3K for San Francisco.  You'll find the message in a special
NTS RADIOGRAM format, with a preamble, address, telephone number, text and
signature, ready for delivery.  After the message has been saved to your
printer or disk, the message should be erased from the BBS.  You use the KT
command, which means "Kill Traffic", followed by the message number.  In
this case you would enter KT 7839 to erase the message you took from the
BBS.  This prevents the message from being delivered again by someone else.

DELIVERING OR RELAYING A MESSAGE: Once you have received the NTS Radiogram,
it should, of course, be handled expeditiously.  If it's for your immediate
area, you should deliver the message by telephone.  If you took the message
for delivery to the local traffic net, you should make an effort to see
that it gets relayed as quickly as possible.

SENDING MESSAGES: Any amateur can originate a message on behalf of another
individual, whether the person is a licensed amateur or not.  It is the
responsibility of the originating amateur, however, to see that the message
is in proper form before it's transmitted.  A special format is used for
NTS traffic so that the messages are compatible across the entire network.
Each message should contain the following components in the order given:
number, precedence, handling instructions (optional), the station of
origin, check, place of origin, time filed, date, address, telephone
number, text and signature.

When the message is ready to be entered into your local BBS, you must use
the ST command, which means "Send Traffic", followed by the zip code of the
destination city, then @ NTS followed by the two letter state abbreviation.
The form used is ST ZIPCODE @ NTSxx.  A message being sent to Boston, MA
02109 would be entered as follows:  ST 02109 @ NTSMA and a message for Iowa
City, IA 52245 would be entered as ST 52245 @ NTSIA.  The message SUBJECT
or TITLE should contain "QTC 1" followed by the destination city and state
and the telephone area code and exchange, if available.  See the examples
in the listing above.  Only one NTS message should be included in each
packet message.  The actual radiogram should be included entirely within
the TEXT of the packet message, including all of the components listed
above.  End the message with the usual Control-Z.

IN TIME OF EMERGENCY: The National Traffic System functions on a daily
basis as a public service for both your fellow hams and the general public.
It serves another function as well.  The NTS provides a well oiled and
trained national system of experienced traffic handlers able to handle
large volumes of third party traffic accurately and efficiently during
disasters.  At least that is the goal.

REFERENCE MATERIAL:  The ARRL booklet "An Introduction to Operating an
Amateur Radio Station" offers detailed information on handling and
preparing NTS Radiograms.  The file "HOWTO.NTS" gives a complete rundown
on how to prepare and send an NTS message on packet.  Check your local BBS
files section for it.  You should also find several other files such as
"DELIVERY.NTS" and "WHATIS.NTS" that will provide you with a wealth of
information.  Check them out if you want to get involved.  Your help will
be welcome!
