"Lew Hodgett" wrote in message ink.net... A couple of questions. My only interest in HAM radio is to be able to get necessary weather forecasts and communicate with other sailors who happen to be in my net at the moment, when I'm at sea or in an anchorage. SNIP Given all of the above, what are my best options? Lew If the "other sailors who happen to be in my net" include Ham operators, then the answer is obvious, get a license. Otherwise Marine SSB offers various nets for cruisers. If you cruise the east coast/ Bahamas - there is the Cruiseheimers Net every morning at 8:30 local with much of the same information (and people) as on the Waterway Cruising Net (Hams at 7:45). You are free to listen to the Ham nets with out a license. In an emergency, you can do what you need to do. Many mariners will meet up on Cruisheimers (Marine SSB) and establish other smaller nets / get togethers on other Marine SSB channels. Sailmail (as well as other commercial services) is an excellent way to get PACTOR email and weather. Obviously, and decent HF receiver will get you access to the USCG WEFAX data. OCENS (and many others) provides software to get this HF data as well as download sat weather images (hardware obviously costs...images are free). OCENS also provides a highly optimized format of may of the standard weather charts for efficient download over cell phone or Sat Phone. VHF weather from NOAA in the US and various helpful people throughout the Bahamas. Herb Hilgenberg (http://www3.sympatico.ca/hehilgen/vax498.htm) on marine SSB is probably the best weather source available for mariners on the Atlantic. There is always information pertaining to the Bahamas / Bahamas crossing during season. Depending on where you are, Marine VHF is the means of communicating between boats with in VHF range of each other. Other than on HAM nets, I don't hear a lot of HAMs communicating boat-to-boat ---- Not that it doesn't happen, just not the regular local gab line. If traveling within 25 miles of the coast, a No-Code license will get you access to all the Hams / Ham repeaters along your route. I find this useful for local restaurant recommendations. You have many options if you have decided that you don't want to learn code. HF HAM is the only one you have opted out of. |

Well, if you just plan to run down the coast a ways and use sailmail or check in with the local nets you probably don't need to learn much. But if you are half way to Hawaii and the "eathers" are not right you need to know some about propagation in order to choose a good frequency. There are also several knobs on that black box that can either screw up your signal or make it clear so it is better to know what effect each has and how to use it. A good bit, if not the majority, of the tests these days is about safety and the rules that try to prevent the bands from becoming totally chaotic. Compared to 40 years ago when you pretty well had to know how to build a transmitter out of bailing wire and cow patties the technical part these days is laughable. The only hard part is memorizing the band frequencies. Ham radio is more than a utility. I realize that building boats on the scale that we are turns us into a sort of hermit but sitting out an off season in some foreign anchorage it can become a center of your social life. Granted my question was a little tongue in cheek, but it has been a slow day at the boat yard. (90+F tends to restrict your glass laying schedule). Along the same "time marches on" theme, it has been announced that the USN will cease using paper charts. Conversion to be complete in this decade. That one will be interestingG. Lew |

According to a book I read some time ago these little boxes (there were 4 of them originally and I guess this has not changed) were built to be bullet-proof. The code was written by IBM and every one of the 100,000 plus lines was verified more than once. The book said it was some of the most expensive code ever written. |

I wasn't trying to imply that the main computers which control the shuttle (which are 4x redundant) ran Windows! I know full well that those systems probably cost millions. But one has to consider that the laptops which the shuttle astronauts use are Windows based. My Northstar 961 chartplotter is based upon Windows NT. It's extremely stable. I built my first computer (SWTPC 6800) in 1974 from chips. I've spent 20+ years in the software industry of which 5 were spent in DEC's fault tolerant group where I implemented systems with 99.999% uptime. That group later went on to form Marathon Technolgies http://www.marathontechnologies.com/ which based their solutions on Windows platforms and provides 99.999% uptime. You'll find that the vast majority of crashes are caused by I/O system synchronization problems. The next time that you say "OK" to the fact that the drivers haven't been certified by MicroSoft, maybe you should realize that this may be a major contributor to the stability of your system. So yes, people can throw stones at Microsoft, but often they really don't understand many of the underlying issues. Please, let's not make this a religious war and go back to the topic at hand...FCC and code requirements. -- Geoff |

NASA's code has been used as a textbook example of how coding shouldn't be done. Computers and programming have evolved greatly since the most recent NASA (almost wrote NACA, since they are that old) OSs were built. Sometimes it's not so much how well the bear dances but that it dances at all. "Glenn Ashmore" wrote in news:Xk4Le.17506$Ie.6745@lakeread03: Who's running on a $100K computer?

Yes, space has special concerns, but it shouldn't take 10 or more years to develop a space-hardened computer. Yes, it's rocket science, but the problem isn't the technicians, but the bureaucrats. Current machines are TWENTY times faster, with hundreds of times more capacity.
