   Speaking of radar jammers, in the 1980s they were all the rage, where we   
   built them ourselves, but we never put them in practice in cars. We also   
   used the Kodak IR chips to build our own distance sensors for parking.   
      
   In my Suzuki GT650EX I wired a two transistor speaker and microphone into   
   the two helmets for traveling on long trips with two people. They were the   
   big tophat transistors about the size of a quarter.   
      
   My how times have changed.   
      
   In the USA, radar jamming is illegal because you can't transmit on licensed   
   frequencies, but you can receive and decipher the signals on those   
   frequencies. The point is that it's "free speech", where any look at Nazi   
   Germany or any repressive regime shows how important radio freedom is.   
      
   Regarding AJL's point about pointing the gun down and Carlos' point about   
   reflection, if a huge semi is behind you and you're on a motorcycle, we've   
   always been told the gun will read the truck more likely than reading you.   
      
   AJL can expound on that, plus for those who don't know about the cosine, it   
   matters greatly the angle where the cop tries to be head on if possible.   
      
   Back to jamming, there are famous stories of people jamming on their daily   
   commute where the government spent weeks finding them so it's not easy.   
      
   As I recall, there were complaints from a local utility about an   
   unauthorized interference, and then when the FACC investigated, it happened   
   at the same commute time every day of the week except weekends. :)   
      
   We could dig up the story as it was infamous at the time it happened.
