Below is a crib from the Island Packet mailing list I monitor, and my
response: WeatherFAX basics by Mike Trautman, K9MLT I've been exploring the WeatherFax system because I would like to get these valuable weather graphics and photos while far from shore on my sailboat, Island Princess. We sailors can't do anything about the weather, but knowing what is coming and having some indication how bad it is, and how long it will last can make a sailing voyage much more pleasant for captian and crew. Hams and Marine SSB users have radios that work well with this system, but it's also possilbe to utilize this great resource with an inexpensive Single Side Band receiver and a laptop computer's sound card input! Some of the graphics availabe include: Surface analysis, Wind/Wave forcasts, Cyclone/Storm, High Wind/Waves, Wave period/direction, and Photographic satelite images. You can view currwnr examples of these graphics on the Internet at the New Orleans site: http://weather.noaa.gov/fax/gulf.shtml Here's the main NOAA URL for WeatherFax, also called WeFax or RadioFax http://www.nws.noaa.gov/om/marine/radiofax.htm The frequencies of the U.S. stations broadcasting WeatherFax are listed toward the bottom of the URL. Scroll down to see them. I've been dialing in to broadcasts from Boston and New Orleans. Example: New Orleans - New Orleans (NMG) 4317.9, 8503.9, 12789.9, 17146.4(12,18Z) kHz IMPORTANT! - The frequency is for USB and the actual tuning on my reciever is the listed frequency minus 1.9 Hz, Therefore New Orlean's 4317.9 comes in on 4316.0 USB. From Central Illinois, I've been getting good reception on 17m and 20m during the day and mediocre reception on 40m and 80m at night. The schedule starts at 00:00/12:00 for New Orleans (CST) and 01:00/13:00 for Boston (CST). It can take 30 minutes for the larger files to transmit. The software I've been using is SeaTTY. It's a free download at: http://www.dxsoft.com/seatty.htm They ask for a $35 registration fee if you like the software. Which I plan on doing. There are other sources for software (and hardware) listed on the main NOAA site. I use a 1/8" male/male stereo plug, from the earphone jack of my Yeasu FD857d transceiver directly to the Mic jack on my laptop. So far I haven't seen any particular effect from changing the record volume in Windows. It took me some experimentation to realize I did not need my TNC in the loop at all. The manufacturers do not make this option clear while describing their product. I think you could use any receiver that can receive Single Side Band broadcasts. A fancy Ham rig is not needed. Note: for about $250 you can buy a dedicated "WeatherFax" receiver that will connect to your computer, or even direct to a printer and eliminate some hardware. For non Hams and boaters who don't have Marine SSB aboard, a "YachtBoy" SSB portable receiver, with a good external antenna would probably do the job, . Tip: The software allows you to fine "tune" the frequency even when AFC is turned on. You can move the red vertical lines so one lines up with the peak in the spectrum display and improve the resulting graphic's sharpness a bit. I'm NEW to this technology, so don't take my word as gospel. But do check out the technology if you would like your own weather information out where the Weather Channel doesn't reach! Happy Sailing! Mike Trautman, K9MLT s/v Island Princess, Island Packet, 27/9 Sarasota, FL Listees, this is very timely for me, as we're just about to get our HF radio gear, going with the Icom M-802 and the MMSI antenna. We already have a satellite picture capture hardware setup - which allows us to see ~1/hour 45* downlook picture from a satellite overhead. That, of course, will give us a very good representation of what's around us, covering lots of ground. However, there's no intelligence along with that - just a great ability to (if we record them) make a visual track of what any particular weather system is doing. For intelligence, our supplier, Steve Bowden, of Sea Tech Systems, has recommended Xaxero WeatherFax 2000 - USB, a dedicated program. No doubt there are lots of bells and whistles in this $199 program - but not having used any, let alone this and the referred one, I can't speak to the merits of either. Is there anyone here who's used the Xax, and can give me a reason to spend that vs the shareware Mike recommends? Thanks.

Is there anyone here who's used the Xax, and can give me a reason to spend that vs the shareware Mike recommends? I have a similar lashup on my own boat for weather fax. I use a Sony 2010 with a headphone wire to the mike input on my laptop and the SeaTTY software. I don't use any external antenna, just the attached whip and I can pull in either Hawaii or Alaska at different times of day. The fax picture is clear and can be drawn on etc on the computer screen. The whole works can be set up to work automatically so you don't have to get up to copy the weather. I can also copy NAVTEX and teletype with the same software. On the tall ship I command, I use a dedicated Furuno wefax machine and it is not nearly as easy. First of all I have no graphic of the signal and tuning the receiver is always a challenge. It runs through a complicated antenna system as well. When it is set to automatic I sometimes find it has gone through reams of paper with a lousy signal wasting expensive paper that is always in short supply at sea. In order that I don't have to rely on this system I am connecting my HF radio onboard to a laptop so I can have a similar setup as in my own boat. The SeaTTY software is a thing of beauty. The trick is the radio. You have to have a decent SW radio capable of SSB. The Sony 2010 is ideal. Gaz |

That is true but if you already have a decent SSB radio like the ICOM M-802 and a Pactor TNC for Winlink or Sailmail, you already have everything you need. The Airmail software does everthing automatically including setting the frequency and mode on the SSB. Fax images and NAVTEX broadcasts get saved to your laptop as they arrive. |

i'm in the middle of all this right now. i have an icom 706-mkiig, an
old laptop, etc, and have been prototyping a basic setup to do all of this, including airmail. i haven't gotten very far because i passed the written tests for "extra" but haven't taken the morse test yet, so i haven't been on HF. through a really dumb mistake i also hooked one of my deep cycle's up backwards and burned a diode in the icom (and another radio) and had to send it off to have the diode replaced, so i have been waiting a week or two on that and haven't been messing with the setup. i am prototyping this system in an old truck instead of a boat so that i can work on it more conveniently and get it all working, then later i'll move it over. i don't have a TNC and have been hopeful that i can use a soundmodem type of setup instead of a TNC. i haven't seen a bit of this work yet! i'm just full of hope and optimism! lol. the only thing i've actually done with the icom is use vhf/ufh and hear a satellite using a yagi antenna, that's it so far! i was in the middle of installing an icom antenna tuner and HF antenna on the truck when i made that battery mistake, so i haven't even heard anything on HF frequencies yet. i'm excited to get all of this working and gain some real experience using it, i will feel a lot safer knowing i have all of this available to me in addition to the usual radio equipment. you can never have too many radios! ![]() |

I got this reply (and my response) in the Island Packet group - anyone here
have experience like this?? To: "Island Packet Owners Discussion List" ; Subject: sailmail and airmail via JVCOMM32 (was) [islandpacket] WeatherFax Hi, Tim, and group: You might check out JVCOMM32 for wx fax and NAVTEX. If you do sailmail/airmail they have an add on for fax and NAVTEX also. JVCOMM32 can use the sound card or pactor modem and sailmail/airmail uses ONLY pactor modem... FriendShip IP35-077 Tim WB5SBF I have not yet visited nor explored the site, trusting in your experience and forebearance. Are you saying that this will do ham/SSB email by software, not PACTOR modem?? Thanks.

Best is to get Pactor III. Pactor III is so much faster than Pactor II, and only a couple of stations have Pactor I. Works great. Kelton s/v Isle Escape |

False alarm. I missed the "only" part, below.
I'm trying desperately not to have to lay out another boatbuckfifty just to get slow email, and thought I'd read that this SW would do the job. Meanwhile, my up-the-mast wifi isn't yet ready for prime time, still being bogged down in technicalities. More meanwhile, I'm just looking for more input on various wefax softwares, having decided to pass on the Xaxero for the moment.

I feel your pain but it's actually a good investment. If it weren't for my Pactor III TNC I would get almost no routine use of the SSB. The combination of SSB, Pactor and Airmail gives you offshore position reporting, automatic NAVTEX, automatic WEFAX, and EMAIL, all without an internet connection. |

The SeaTTY worked instantly. JVCOMM32 didn't have an email function.. I think the guy is saying that the Sailmail function needs a pactor modem. Gaz |
