If you had to use CW to save someone's life, would that person die?

If the Titanic and California had been so equipped, the California could probably have gotten there before the Titanic sank. The GPS-based emergency system doesn't go to sleep like the California's CW operator did. Oh, you mean he didn't hear the automatic annunciator they had in use in those days? Mechanical and clunky, but it worked. The only thing the GPS-based system does is give you an exact location - it doesn't notify anyone of anything. Plain old radio does that, the same as it did back then. If radio had not existed, the next passing ship would have rescued any survivors. That's the way it was for centuries before the invention of radio. The way it usually was in the centuries before radio (just ask the crew of the Nuestra Senora de Atocha) was that when the ship sank the people on her died. (The Atocha's crew were all hardened sailors, yet only 3 crew members - out of 265 people aboard - clung to the wreckage long enough to be rescued.) There were often survivors in lifeboats waiting to be picked up in the shipping lanes. Well-equipped lifeboats could survive for weeks in calm waters as did the ejected sailors of "Bounty" fame. 1) There weren't enough lifeboats in the Titanic. 2) They weren't "equipped". 3) The crew of the bounty were sailors used to pulling oars for hours at a time. The passengers of the Titanic - those who were allowed to get to the lifeboats - were pampered women and children, not used to, or able to, row a heavy wooden lifeboat anywhere. 4) People who are wet and in their night clothes - most of those who made it to the lifeboats - don't survive very long in sub-Arctic climes. But it's nice to reminisce about what happened, even if it never did. |

Passing ships rescue survivors. -- 73, Cecil, http://www.qsl.net/w5dxp |

"EPIRB - Emergency Position Indicating Radio Beacons, or EPIRBs, are used when a ship is in distress, to emit a radio signal marking the ship's location." GPS systems are receivers. Transmitters that use GPS-derived data aren't GPS-based systems, they're transmitter-based systems. No transmitter, no notification. No GPS, notification is a little less accurate, that's all. If radio had not existed, the next passing ship would have rescued any survivors.

(The Atocha's crew were all hardened sailors, yet only 3 crew members - out of 265 people aboard - clung to the wreckage long enough to be rescued.) Yes, that's what I said. Passing ships rescue survivors. Or, in this case, ships that were part of the same flotilla (they didn't have to have any luck in being in the area) only managed to rescue about 1% of the survivors. If they had waited for "passing ships", their grandchildren would have been too old for rescue. Most shipwreck survivors who are rescued aren't rescued by ships that just happen to be passing, they're rescued by ships that knew about the wreck and responded. (Before radio, most shipwreck survivors weren't rescued.) |

Can you prove that assertion? :-) Most shipwreck survivors who are rescued aren't rescued by ships that just happen to be passing, they're rescued by ships that knew about the wreck and responded. (Before radio, most shipwreck survivors weren't rescued.) All that is true. If one was away from the shipping lanes, one was SOL or USCWAP. However, if one was in the shipping lanes with a flare, one at least had a chance of being rescued. According to my nephew, one of our ancestors was rescued in such a manner. Presumably, if that had not happened, neither he nor I would exist. -- 73, Cecil http://www.qsl.net/w5dxp |

Notification isn't made by GPS. We had radio-based notification systems long before we had the GPS. If one was away from the shipping lanes, one was SOL or USCWAP. However, if one was in the shipping lanes with a flare, one at least had a chance of being rescued. Once flares had been invented. We've been sailing the seas for at least 4,000 years, over 3,500 of them without radios, flares or other means of communications to ships or land installations we couldn't already see. |

Your assertion that transmitting GPS coordinates is not a GPS-based system is obviously ridiculous and hopefully just a bad joke. Better luck next time. -- 73, Cecil http://www.qsl.net/w5dxp |
