10 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 ) 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.

28 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.)

34 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.  Source:

66 Installation (Hardware Needed)

67 A Professional Installation Generally Includes:
Interface the radio to the HF-modem in the technically "best" fashion.   If there is an "accessory" jack available on the radio that includes the necessary signals, it should ALWAYS be used.  The use of the "Mic" jack should be avoided.  A HF-modem to SSB cable should be provided that has shields connected on both ends and that has ferrites installed on both ends. If the radio is capable of remote control (Icom M710, Icom M700pro, Icom M802, Icom M710RT, SGC SG-2000, SEA-235), provide the remote control cable.  If necessary for the PTC-IIe or PTC-IIex, provide and install a USB-serial adapter.  If necessary for the Icom M700pro, provide the CI-V or Icom OPC-478 level shifter for the pin jack.  See details in the Application Notes. Update the firmware in the SCS PTC modem to the latest version.  Upgrade the modem to include an electronic serial number (ESN) if necessary (old PTC-II and old PTC-IIe modems only). Install ferrites at both ends of all cables including the RS232 cable between the HF-modem and the PC, the remote control wire to the radio, the audio/PTT cable between the HF-modem and the radio, and the tuner control wire.  Install a Line Isolator (next to the tuner) in the coax from radio to tuner (for details see the SailMail Primer). Check and if necessary improve the ground system and the ground connection to the tuner.  (Do not compromise on this item.) Check and if necessary improve the routing of the antenna wire from the tuner to the backstay.  Make sure that the antenna wire has stand-offs supporting it at least 2 inches from any grounded wires or stanchions. Adjust the audio modulation levels on the modem using a directional power meter.   See the application note in the SailMail Primer on level setting for details. Evaluate the system for RF self-modulation problems. Evaluate the boat's other equipment (inverters, motors etc) for interference with the SSB.  Either install filters or inform the owner of what gear needs to be shut off before using SailMail (probably inverters). If the radio can not be remote controlled, then program the radio with the SailMail frequencies, including the appropriate mode. Provide a printed copy of the latest SailMail Primer , T&C's, and the SailMail FCC licenses. Provide a backup copy of the AirMail download from the SailMail website download page, on floppy disks. Test the system and demonstrate the use of the system to the customer. Source:
