I do not know if an On-Star operator can talk to an equipped vehicle at On-Stars initiative, but certainly we have the start of a system with a two-way radio with a satellite comms link. Why not -- they can eavesdrop on a selected vehicle, as was proven once when the cops asked them to do so to a vehicle involved in a kidnap. And now thwt I think of it, they can iniiate a conversation when they detect an airbag deployment. |

"Ever hear of Quiet Zone rulings?" Is that why air raid sirens aren`t tested Fridays at noon anymore? When life is at risk, quiet zones, like radio rules, don`t apply. Best regards, Richard Harrison, KB5WZI |

The rest you have to figure out. -- Drop the alphabet for email |

If an On-Star device, would be true two way, with GPS tracking, with either end of the link able to activate the system. One could broadcast a message to every active unit, either universally, or, based upon GPS tracking to every unit with prescribed geo coordinates. There already exists a somewhat similar system to broadcast weather alerts to a passive receiver, although not normally deployed in cars. Boaters already can have a Digital Selective Calling VHF radio in their boats by which a coast guard can issue warnings. Such a system is being mandated in the UK by a phase in process (e.g. new radios with the old paradigm cannot be marketed unless they have DSC.) And horror of horrors, one could alway investigate Broadband over Powerlines (BPL). Wouldn't that give us hams some gas. W3JT The issue of installing a proprietary receiving device inside automobiles, mandated by federal action, is one that is being given serious conversation. The one problem that appears to be an issue is the liability one. It will be a matter of time that someone will sue saying that the system scared them or distracted them and caused this or tat accident. -- Drop the alphabet for email |

Is a quiet zone a place like Placentia Ca. which had, for the railroad, become a manditory blow your full set of air horns long and loud right next to the bedroom windows every time you pass by no matter what time of day or night it is, and where the locals have passed an ordinance that says they're sick and tired of it? |

Here's a "heads up" for you, Ken. There are over ten FedGov agencies, several legal teams and the rail lines that are working with diligence on this, and similar, projects with the full intent of attempting to pull this off. While you sit on the sidelines and nay-say. If I had a dime for cheap comments like yours, I could fund this project out of petty cash. So goes the nature of those who do and those who comment about the doers. -- Drop the alphabet for email It may be a fine project which will produce the goods, but let's look at the way you've brought it he - you wanted help to get up a truck-mounted transmitted to over-ride all AM/FM communications in an area. You wanted to drive the truck at up to 70mph through a disaster/emergency area, for no adequately explained reason (the RF is going for a mile or two outside the area, so why drive the truck?). You got told why it's impractical as described. - you suddenly changed it to a loco mounted project. You struck gold on this one as there are people here who clearly have industry experience. You're not poo-poo'ing their skepticism, but certainly not fazed (may not be a bad thing....). Why not pour the funds into controlling all these uncontrolled level crossings instead of producing a 'box' to go on every loco that may drive through the US? - you are trying to get commercial advice in a Ham group - is this the right venue?? I'd have thought not, though it's certainly cheap. - having ten agencies etc etc on your side may get the project through, but is it the right solution to whichever problem it's attacking? - 'nay-sayers' are a pain-in-the-arse, agreed - no-one likes them! - but sometimes you need to hear the other side. Cheers. Ken |
