- 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!
