WINLINK 2000 And Other Options
2
What is WINLINK 2000? ● A system of sending and receiving email over Amateur Radio ● HF – used widely by campers, boaters, missionaries ● VHF/UHF + up – growing use for ARES and disaster communications Was used in Katrina Disaster and others ● A BIG controversy!
3
WINLINK Architecture Central Message Server (CMS) The Central Message Servers are the hub of WINLINK. There are three of them around the world, mirrored to each other via the Internet. They provide mail routing and other important functions.
4
Winlink Architecture (2) Central Message Server (CMS) PMBO or RMS The Participating Mailbox (PMBO), or 'Radio Message Server' provides local or regional mail routing. It can communicate to the CMS via the Internet, or in an emergency, via HF radio and another PMBO.
5
Winlink Architecture (3) Central Message Server (CMS) PMBO or RMS TELPACTELPAC TELPAC is normally used as a gateway between radio stations and the PMBO. It can also be built directly into the PMBO, so stations using radio can connect directly to the PMBO.
6
WinLink Architecture (4) Central Message Server (CMS) PMBO or RMS TELPACTELPAC PACLINK PACLINK provides a way to tie existing email clients into WINLINK. A PACLINK node can be connected to an existing email network, and will forward email to and from the PMBO. PACLINK is normally connected via radio, either PACTOR on HF or PACKET radio, 802.11 or DSTAR on VHF/UHF.
7
WinLink Architecture(5) Central Message Server (CMS) PMBO or RMS TELPACTELPAC PACLINK AIRMAIL AIRMAIL is a standalone email client. Normally it is used on HF to connect to a remote TELPAC gateway. It can also be used on VHF with a packet TNC.
8
Recommended Equipment ● VHF/UHF – 9600 baud packet radio PC's, TNC's and radios for AIRMAIL portables PC's, TNC's and radios for PACLINK servers PC with Internet connection for TELPAC -or- PC with Internet connection for TELPAC and local PMBO or RMS (Emergency PMBO) ● Without Internet connection, PMBO can route mail to all local PACLINK or AIRMAIL clients DSTAR and 802.11 networks are being used

Winlink 2000 Digital Messaging for ARES ® By Steve Waterman, K4CJX (help from Loring Kutchins, W3QA) Winlink 2000 Network Administrator, Winlink 2000 Development Team LORING A KUTCHINS revised January 20, 2005 “Our primary mission is to provide Global digital communications for the benefit, safety and well-being of the user community, anywhere, anytime, anyplace.”
11
In addition to our individual ARES® users, we stand by our Commitment to our community Government and Civil Agencies :
12
To Supply De facto e-mail: using their existing e-mail programs, on their own computers in their own offices, with no additional invasive software, seamlessly, transparently, from user-to-user. from inside their own County or around the world from inside a disaster area, and without normal e-mail servers or Internet links. This is the purpose of Winlink 2000 E-mail via Amateur Radio
13
Normal E-mail requires an internet connection Between Agencies Between an Agency and the Field Between an Agency to multi-points Between Agencies and anywhere! Agency Focus on Emergency digital communications
14
Agency Focus If a community “Last Mile” internet link is broken, or the agency e-mail server is down, e-mail cannot flow. “What the ????” “Critical Medical & Tactical Info sent!” X
15
The “last mile” is an important concept in Emergency Communications. The “last mile” is the path across an area where conventional communications have been disrupted or overloaded by an incident.
16
Unfortunately, in today’s World, we cannot predict the frequency, size, nature or location of our disaster areas! We be must prepared, Globally. Local? Regional? Global?
17
Winlink 2000 is primarily a donated, dependable, transparent, back-up E-mail system that bridges any distance. Radio
18
For the end user it must: ● look like e-mail and use familiar software like Outlook ● have an address book and a spell-checker ● allow multiple recipients (to:, cc:) ● send multiple attachments ● be able to use tactical email addresses ● and NOT add to the stress or learning curve when in an emergency situation
19
System Requirements: It must work on multiple computers on a LAN without additional desktop software, and not invade security, be automated, use available and future digital radio modes, interface with commercial communications systems like telephone, cellular telephone, the Internet, etc., have speed, performance and accuracy, and immediately deliver emergency traffic seamlessly, end- to-end.
20
Why?
21
“Written documents impose their own kind of discipline” Albert Einstein Moving into the 21 st Century “I can’t work without a blackboard!”
22
Why? Traditional role of Amateur Radio support: ● Report health and welfare of affected public Voice communications among served agencies (EOC's, hospitals, shelters, and incident command.) ● Site tactical support – Incident Command, search and rescue, damage and storm reporting (SKYWARN). ● “Formal,” Structured written emergency traffic handling.
23
Why? Our traditional methods fail for complex message handling in today’s agency environment! ● Since the advent of e-mail: ● Need for delivering written procedures, lists, graphics, images, and Pre-defined, formatted, documents to multiple recipients! ● Multiple recipient e-mail with binary attachments is the de facto standard to carry written information. ● Hand-written message forms are seldom used, and are not transparent to normal operations! ● For complex messages, voice, Morse code, Radiograms, and traditional Packet radio won’t do… ● way too slow, translation required, inflexible, prone to error, no permanent record, not self-originating, not point-to-multipoint. ● doesn’t go end-to-end from user-to-user on their own computers in their own offices & no attachments and no automatic distribution..
24
Emergency Digital (written) Complex Communications For Community Agencies We can keep Agencies connected without an immediate Internet connection. With Telex? When was the last time an agency used Telex? With a Telegram? When was the last time they sent a Telegram? With a voice relayed NTS Radiogram or MarsGram? (could be an attachment) With W0RLI Packet “H-routing”? “HUH???” “Do what???” The accepted Global standard is now SMTP e-mail ! Bottom Line: Let’s make EmComm as easy & transparent as possible for those who need it during an emergency situation. Let’s not forget: It is their “party” and we want to be invited!
25
Why? The ARRL is now implementing a National Plan July, 2003: In cooperation with its partnership with Homeland Security, and at their recommendation, the ARRL Board has agreed to provide a nationwide digital system to enhance the communications capability of the Amateur Radio Emergency Service (ARES®). There are situations, the Board said, when ARES® "must have the capability to pass digital traffic across the nation quickly and accurately.” It must also be transparent, seamless,end-to-end, and take only minutes from origination to destination.

Second Telpac route is telnet to the K4CJX PMBO Outbound EOC PMBO D-Star route to external Internet gateway. Proposed ICOM D-Star (100,000 bps) I Alternate Internet via D-Star
45
So, What’s Next? Examine the option: what else is available for complex radio messaging? Does it provide end-to-end, transparent, multiple recipient de facto e-mail to the community Served Agencies desktops? Make a “yes/no” decision about Winlink 2000. If “yes,” then... –Learn to use Airmail, Telpac and Paclink. –Deploy local Telpac gateway(s). –Deploy mobile Paclink & fixed Paclink LANs in places where it will be of value during an emergency. –Deploy VHF/UHF new or existing links to bring it all together. –Deploy self-powered, mobile/fixed Airmail, long-range HF Stations. –Consider a non-public “hubbing” PMBO for the area Meanwhile…..
46
Devise a Plan! Insure that there is no duplication of efforts in your “last mile” coverage area. Set up an strategy for implementation with your local ARRL ARES® or RACES organization. Set up a time-line for each task. –Coordinate efforts with the Winlink 2000 Development Team, EC’s,SECs,DECs/SM, etc. –Ask other ARES® communities for assistance. –Set up personnel responsibilities with Time-lines! –Handle the finances. “How much will it actually cost”? Who should pay? –Involve and commit the end-user. They are the one’s to benefit! Implement the plan in stages. Test it, and Test it again. Provide a presentation and demo for your served agencies. Continue to promote your capabilities.
47
Winlink 2000 is a proven, existing, operational, dependable, redundant, secure, reliable Amateur radio e-mail messaging network that is being made available to the ARES® & RACES communities. (However, each community must put it in place.)
48
APRSLink ● Allows users to send and receive email through WINLINK via APRS ● Allows multi-line messages ● Notifies users when mail is waiting to be downloaded if requested
49
The Controversies ● HF WINLINK uses very expensive gear PACTOR III proprietary modem ● WINLINK relies on Internet connections Not so much anymore ● AUTOMATED stations cause QRM on HF ● Commercial SAILMAIL product available
