A radar detector and a radar jammer??
I was shown a "new" jamming system with two black bars that mount in the grille. It is supposed to defeat the police radar. My question is if you are the only car in a 20mph school zone, and they radar you and the gun does not show a speed, wouldn't you be interfering or obstructing in some way? Cops, please feel free to express an opinion on this. |

Jamming a government radio service will land you in butt-slam federal prison. Jamming requires an active transmitter that sweeps back and forth across the chosen radar band at a sweep rate that translates into a fake MPH reading on the radar. No simple passive device will do the job except at very close range, 20-30 feet at best. The "jammer" you described sounds like a 100% scam. |

They said it sends out a signal. Two rectangular black bars. They were installing it on a new Mercedes SUV. Seemed totally illegal to actually defeat the radar or interfere with police equipment / frequencies. |

Then there's that pesky FCC Part 15, which makes it illegal to use an active jammer in any state.
"47 C.F.R. 15.5b: Operation of an intentional, unintentional, or incidental radiator is subject to the conditions that no harmful interference is caused and that interference must be accepted that may be caused by the operation of an authorized radio station, by another intentional or unintentional radiator, by industrial, scientific and medical (ISM) equipment, or by an incidental radiator." Same reason cell phone jammers are also illegal. |

Non-commercial: Radar detectors are legal in most states except for Virginia, DC, and on military bases. You can't mount them on the windshield in Minnesota and California but can have them elsewhere.
Commercial: Illinois, New Jersey, and New York ban radar detectors in ALL commercial vehicles. Federal law bans them in all commercial vehicles over 10k lbs. Radar jammers: Illegal by federal law; $10k in fines and 1 year in prison. Laser jammers: Legal, though some states (California, Colorado, Illinois, Minnesota, Oklahoma, South Carolina, Utah, Virginia, and DC) ban them. Canada: Radar detectors and laser jammers are illegal except in Alberta, BC, and Saskatchewan. Radar jammers are illegal. Mexico: If the federales want to pull you over - speeding or not - they will do so any how. Mike |

Sounds FCC non-compliant.
Big difference between monitoring spectrum and interfering with it. As far as legal/ethical goes... as long as no meaningful RF leaves your property, I think you are ethically ok, but still legally non-compliant with FCC regs. The RF signals from any police radar jammers would most definitely be leaving your property. |

Morally or legally, what right do "they" have to hit you with radar in the first place? Its only legal because a bunch of legislators says its okay for "them" to radar YOU and ME. "They" are no more morally or legally correct in using the radar gun than I would be in attempting to scramble the radar return signal. Im not a libertarian in any sense of the word, im just one of 350 million sheep who happen to tollerate this kind of intrusion into our lives to help keep State and County and Municipal funds rolling in.

There is no law that says YOU can't use a radar against THEM. 
ETA: you have every right to use a radar speed measuring device to measure their speed. I am not implying in any way that using your own speed measuring radar will have any effect on their speed measuring radar, because it won't. |

I think he's absolutely right. Any kind of radiation you get to hit me with, I should get to hit you with. |

I hate to break this to you but driving in a privilege not right, and therefore you are on their road so you play by their rules. And the reason the radar jammer is illegal is because it transmits a signal, which is illegal due to FCC regulations. You can chose not to drive, and walk, and then you won't need to worry about it. |

Jamming radar, all FCC interference issues aside, you are obstructing law enforcement activity. i.e., not that different than tripping an officer who is running after a mugger. What about flashing your brights to warn about a speed trap? No sir, I was just asking a fellow motorist to dim his brights. Quoted:
While I understand your point, your example is laughable. Granted mugging and speeding are wildly different, and tripping an officer involves actual physical intervention, and my example was of an officer chasing an identified criminal as opposed to looking for a crime that may or may not happen . . . yeah, well, shut up. 
Can you think of a better analogy? |

no, it is stupid. Do not install just on principal. Let alone all the FCC violations. I covered this. I have zero desire for a detector or jammer. Just was shocked this was available. They called it a radar jammer. oh I know, I am just stating in general to anyone that could be reading this thread and get a dumb idea. |

The dumbest part was the "transmitters" were like 4" long and maybe 3/8" square. They were very noticeable in a white Mercedes grille. |

I was hoping you are smarter than that.... you do realize the radar bounces back to the operator, right? Bounces off of what, exactly? IOW, your device pelts my car with radar, why shouldn't I be able to pelt your device with radar at a frequency(ies) of my choosing? |

You can use the exact same type of radar the LEO is using. What you CANNOT do is intentionally transmit harmful interference. The radar the LEOs use is registered with the FCC. Your jammer isn't, and interferes with the lawfully registered radar.

Cops, please feel free to express an opinion on this. You're forgetting that the RADAR readout is still only a confirmation of the visual speed estimate done by the officer. So jam away if you think it'll help you. Of course, there are laws against the jammers, so good luck with that |

Ethical, or legal? Either. Please discuss. I don't plan on owning either, but both are legal here I'm told.  Radar jammers are microwave transmitters and therefore require an operating license from the FCC. The state may not have a ban on them, just like most states do not ban radar detectors. But if you got pulled over by the cops and they find you using a jammer, your name will probably end up at the FCC and a very expensive visit to you might take place. |
