Also keeps those pesky UFO's in check:-)....
Hmmm..I though cars were better shielded than that. Article: http://www.guardian.co.uk/crime/arti...259138,00.html 73, Chip N1IR |

Article: http://www.guardian.co.uk/crime/arti...259138,00.html 73, Chip N1IR In the UK, we're not supposed to use 'unproved' commercial equipment in modern cars (although I think we can still use homebrew). This is supposedly to avoid the risk of interfering with the electronics (although I can't really think why 'approved' equipment should be better). It's all to do with being a part of the European Community, and the rule-making bureaucrats in Brussels. Obviously, the real solution to the problem would be to improve the immunity of the car electronics (which costs), but you now have a good reason to justify not doing this. In the UK, we pay a TV licence. There are detector vans which track down offenders. The obvious way was to look for the radiation of the local oscillator in the tuner. However, a radiating local oscillator is a 'bad thing' because it interferes with things. With modern sets, it's probably easier to look for the rubbish from the switch-mode power supplies (which is often worse when the set is in standby). It used to be said that the TV manufacturers were actually willing to improve their designs in order to reduce the radiation, but were pressured not to do so! I'm not sure how true any of this is. I've a sneaky feeling that costs again come into it somewhere. Cheers, Ian. -- |

What prevents the RF from also shutting down the engine in the Looney Van? The cops will be issued Looney Vans equipped with RF-proof 1956 Stromberg carburetors or what?? That would thrill the EPA and the EU envirofreaks no end . . Sometimes I wonder about these academics . . last month it was the University of Rhode Island . . Howard w3rv |

That would thrill the EPA and the EU envirofreaks no end . . Maybe you haven't noticed it, but government regularly exempts itself from the picky regulations that they impose on the general populace. It's not the carb that's the RF sensitive element, it's the Engine Control Computer which the zappers attempt to toast. That means that the ideal immune vehicle would be about pre-1980, with a Kettering ignition system. However, the 70's cars were notorious for trying to reduce exhaust emissions with pneumatics, thermal delays, and other non-electronic systems. Those systems created balky, stall-prone engines, so we need to move the date back to about 1970. Ed wb6wsn |

I can see it know. Cops are chasing some sleaze. He's going at great speed
in traffic, causing a danger to everyone. Cops let loose with their RF gun disabling sleaze's car, their own and fifteen others on the road. One of the innocents affected is a 98 pound woman that can't control her car without the power steering. She looses control causing a multicar pileup. Yep, sounds safer to me.
