Sailmail/Winlink2000/Airmail Introduction The SailMail Association is a non-profit association of yacht owners that operates and maintains a network of private coast stations in the Maritime Mobile Radio Service. The Association provides radioprinter (e.g. Internet email) communications for its members on a cooperative basis, in order to meet the private business and operational needs of the members' yachts. The SailMail Association provides worldwide coverage through the operation of 16 stations in North America, Hawaii, Australia, Southeast Asia, South Africa and Europe. Sailmail uses the same Pactor technology as the ham radio system, and supports Pactor-1, Pactor-2 and Pactor-3 on all frequencies at all stations. Airmail can be configured for either ham or Sailmail operation, or both. With the addition of a Sailmail configuration file, the same copy of Airmail can provide service for both the ham radio and Sailmail systems. This allows Sailmail to be used for business-related messages which are not permitted on the ham bands, as well in countries where ham radio third-party traffic is not permitted. Winlink2000 (WL2K) is a new ham-radio MBO system introduced in late 1999 by Hans Kessler N8PGR, Vic Poor W5SMM, Rick Meuthing KN6KB and Steve Waterman K4CJX. WL2K is fully integrated with the Internet, and uses Internet message forwarding to make user messages available at any station which they normally connect with. The Winlink-2000 system provides worldwide coverage through the operation of 49 stations in North America, Hawaii, Australia, Southeast Asia, South Africa and Europe. Airmail software operates as a "smart client" for accessing both WL2K and Sailmail networks.

Operating Procedure for Airmail Terminal Program (HF Radio) • Posting message using HF Terminal program • Build email message and “Post” in Airmail Message Index (outbox) • Turn on HF Radio and modem • Open the Airmail “Propagation” program (View+Propagation) from Airmail Message Index window to determine what station/PMBO and frequency to connect to • Open Airmail “HF Terminal” program (Module+HF Terminal) from Airmail Message Index window and select station/PMBO and frequency • Listen to make sure frequency is clear, use headphones if engine is running • If frequency is clear hit green button in Terminal Program to send message • If transmit speed is dog slow (< 600 bps) give up and try either another frequency, another station or another time. 1400 bps to 3200 bps are good numbers to see. This is VERY important, don’t beat a dead horse - try later when conditions improve • “Send” message • Receiving message using HF Terminal program • Repeat steps 2 through 6 above • If receive speed is dog slow give up and try either another frequency, another station or another time • “Receive” message into Airmail Message Index (Inbox)
Email via Airmail Terminal Program (Sailmail & Winlink 2000 users) speed sending message Terminal program within Airmail sending an email through the HF radio
Operating Procedure for Airmail Telnet Client (Sailmail & Winlink 2000 users via Internet) • Posting message using Telnet Client program • Build email message and “Post” in Airmail Message Index (outbox) • Open Airmail Telnet Module (Module+Telnet Client) from Airmail Message Index window and choose Telnet Client Station/PMBO from pull-down list • Hit green button to send message • Receiving message using Telnet Client program • Open Airmail Telnet Module and choose Telnet Client Station/PMBO from pull-down list • Hit green button to receive message The Airmail Telnet Client can be used for sending/receiving email, receiving weather bulletins, receiving GRIB files, sending/receiving position reports. In other words, everything you can do in Airmail Terminal Client at 4,800 bps max can be done through Telnet Client at Internet speeds. We often cruise around an anchorage looking for an open WiFi connection to use
Email via Airmail Telnet Client (Sailmail & Winlink 2000 users) receiving message Note: When using Winlink 2000 Telnet Client, the rules of Amateur Radio do not apply since you are not going out over the HF airways. Business type transactions are allowed but only in Telnet
Example of Sending & Receiving Email We will email off for the text version of this web page so we know what to expect when we land in Opua, NZ. Airmail Telnet Client will be used but Airmail Terminal program would have also worked. The following steps apply for any email sent & received.

6. Send Email 7. Outbox shows Email was sent sending message 8. Receive Response receiving message Send and Receive Email using Telnet Client
9. Inbox shows Email was received 10. Read Text Webpage
Position Reporting • Lets folks at home share in your adventures. Gives them a map to track your progress • Do let folks at home know that the lack of an updated position should not be a cause for alarm • Remember that most position reports are removed if track is not kept current (more on alternatives later) • Position reports allow you to see other cruisers in your area • Don’t report if near sensitive areas like Somalia Coast, Gulf of Aden, Red Sea, Venezuela etc. • Don’t report if you don’t want people to know where you are (running from the Law, bill collectors, mother-in-law etc.)
Let’s find VA2BIC (Claude Gagnon & Carmen on SY-CORAIL IV) The Position Reporter web page within the Winlink 2000 system can be found here: http://www.winlink.org/aprs/aprs.htm
The Winlink 2000 Position Reporter (Ham users only, lookup VA2BIC in first column on left) There are over 6000 Winlink 2000 members and at any one time ~300 to 400 are sending in daily/weekly position reports. If the latest position report entered is over 7 days old, the call sign will not show up on the APRS look-up list until a new position report is entered. Click “View position reports for VA2BIC”

Weather GRIB (gridded binary) File Intro What is GRIB and why does it provide so much for so little? GRIB is a code form used by operational meteorological centers for storing and exchanging meteorological charts and other patterns of wind, sea state, temperature etc. The information is put into a compressed digital, binary format that enables high speed transmission and reception. It is useful to sailors for the efficient reception of charted information using GSM, GPRS, Satellite phones or HF radio to Internet link. GRIB files augment the information one gets from Weather Fax reports. Most common GRIB data shown is surface wind speed & direction, atmospheric pressure and surface temperature. Where does the data come from and what is it? A major source is the US NWS (Numerical Weather Prediction)model, the GFS (Global Forecasting System) which calculates how the weather is expected to develop, For this purpose it defines the atmosphere on a three dimensional grid of points. The lowest level of this model is at about 20 meters above ground (or sea level). This is at a height where the pressure is about 3 hPa (mb) lower than at the surface of the earth. From the forecast wind at this level and using algorithms embodying surface roughness and stability, the NWS derives a forecast at 10 meters. The forecast winds are also used to drive a wave model known as the MMAB Operational Wave Model (aka wwave3). NWS wind data in GRIB format are available, free, from at least two sources. Saildocs provide the wind at the 10 meter height above sea (or ground) level. Global Marine Networks (GMN) provides wind data from the output of wwave3.
