What is the National Traffic System (NTS)? The “RELAY” in American Radio Relay League (ARRL) Started in 1915 as the formal ARRL system to relay messages around the country Transmit & Receive Modes: Voice, CW, Digital NTS and Amateur Radio Emergency Services (ARES) Requirements to join: Any level Ham license & interest ARRL Field Organization Appointments: Official Relay Station (ORS), Digital Relay Station (DRS) & Section Traffic Manager (STM).
Advantages of NTS Messaging Wireless! Send them from anywhere. Use a little HT or a big base station Standard Format Accountability NTS Nets meet daily Speed (digipeater vs. email) When all else fails Fun, good practice & helpful!
NTS Hierarchy and Modes US and Canada organized into Area, Region, and Local Nets 3 Areas 12 Regions Traffic Flow: TCC Area Nets Region Nets Section/ Local Nets Area Nets HF Phone, CW, Digital VHF/UHF Phone, HF Phone, CW, Digital Region Nets Section / Local Nets

Station of Origin: Call sign of station who put the message into NTS format; If N2GS prepares message 1207 for a fellow ham, then puts it onto an NTS packet BBS for relay to Vermont, the originator is. N2GS. If WB2W prepares message 23 for his non-ham neighbor then gives it to N2GS to relay to any NTS net, the originator is. WB2W. 5. Check: The word count in body text only (do not count the address or signature); precede with “ARL” if any of the ARL numbered texts are used (i.e., ARL7). 6.

Signature: There is no “Signature” field, just write-in below text; Name & call sign of author – include phone number if not a ham or if not known on an NTS net.
Radiogram Form Detail (6 of 6) Austin AK2US 7/2/03 2112 EDT REC’D: Call sign from whom you received the message and date & time of receipt. Time may be either your local time (EST/EDT) or Zulu time. Make sure date agrees with time (Zulu is 5 hours ahead of EST – can cause date to roll forward). SENT: Call sign you sent or passed the message to, or to whom you delivered it, with date & time. Also good to note delivery method for your own reference (i.e., via phone or left on Tom’s voicemail). Always leave your call back number if message was left on voicemail!
ARL Numbered Texts Purpose & How Counted ARL Numbered Texts replace common phrases in message body text (i.e., Happy Birthday, Greetings by amateur radio, etc.) Use of ARL texts reduce total message word count – faster and more consistent transmission of text Translated before delivery of message to addressee ARL text numbers are always spelled-out in words (i.e., ARL SEVEN or ARL FORTY SIX) Message word count (check) is written as “ARL#” (i.e., ARL4 or ARL15) to alert operators that message includes at least one ARL numbered text.
ARL Numbered Texts (Examples) ARL FORTY SIX Greetings on your birthday and best wishes for many more to come. ARL FORTY SEVEN Your message to delivered UTC ARL FIFTY Greetings by amateur radio. ARL FIFTY ONE Greetings by amateur radio. This message is sent as a free public service by ham radio operators at . Am having a wonderful time. ARL SIXTY SEVEN Your message number undeliverable because of . Please advise.
How to Deliver an NTS Message Preferred delivery is via telephone. Okay to leave on voicemail or answering machine IF you are comfortable you reached the right person. Radiogram postcard if cannot reach by phone. Service originating station to inform if cannot deliver or if they requested confirmation.
Record Keeping & Reporting (PSHR) Use a log sheet to keep track of your messages Use a PSHR log sheet to tally monthly points for Public Service Honor Roll Report message count (originated, sent, received & delivered) to STM monthly Report PSHR totals to STM STM Dave Struebel WB2FTX [email protected])

Advantages of NTS Digital Available 24/7, 365 days a year Error Free Frequency, Time, Propagation Agile Faster Able to respond and adapt quicker to urgent needs like disaster messages Multiple redundant routing paths NTSD exists at and incorporates all levels of traditional NTS from TCC, through Area, Region, Section and Local .
Not to Replace Traditional NTS Complementary system Trained operators always needed for origination and delivery of messages
Digital Mode History RTTY- After WWII, 5 level Baudot code, mechanical teletypewriters, paper tape storage. Noisy Signals subject to selective fading and drop out errors. Equipment relatively available via surplus route Some units as big as a sub-compact car AMTOR- Still 5 bit code, but with limited error correction. Burst mode-requires fast transmit/receive switching
FCC Authorizes ASCII- late 70's 7 bit code- with some error detection HF Packet- 300 baud, Long bursts, error correcting but needing large signal to noise ratio to properly decode Net result- Many retries, slows down transfer rate
First integrated system- APLINK (Amtor/Packet Link) Bulletin Board System incorporating Amtor on HF with transfer of data to VHF Packet Highly successful but suffers from selective fading With 5 bit encoding- only capital letters. No compression No file transfer
Classic Winlink- Win 3.11/Win 95 Win 98, 2000, XP Modules for AMTOR, CLOVER, PACTOR 1,2, and 3 Along with VHF Packet Scanner function allowing multiple auto calls varying in time, frequency, mode, based upon propagation. Multiple forwarding paths With SCS proprietary modem for Pactor 2 and 3 allows automatic frequency control, automatic power level control Compressed and binary transfer of data
Winlink 2000 (aka WL2K) Developed by Winlink Classic Programmers in late 1990's Uses Pactor 1, 2, and 3 Forwarding via Internet Not widely adopted by NTSD due to concerns with Internet availability due disaster scenario NTSD prefers to forward via RFIndependent of any infrastructure
Autocall
NTSD and Pactor HF NTSD Operates almost exclusively in the automatic control sub-bands 3.585 - 3.600 MHz 7.100 - 7.105 MHz 10.140 - 10.150 MHz 14.095 - 14.0995 MHz 14.1005 - 14.1120 MHz Using Pactor 1, 2, and very limited use of Pactor 3. Pactor 2 and 3 are proprietary modes . All pactor connects start out at Pactor 1 and then shift up to higher speed if the equipment at both ends is compatible. Bandwidth for Pactor 1 and 2 is 500 Hz. pactor 3 will expand its bandwidth up to 2.4 KHz at highest speeds.
