False radar beams?

[Dschubba]

Back when I was in the radio inspector business, there was a court case challenging the legality of the police radars. It turned out they weren't licensed. The guy challenging their legality (who worked with us) was seriously told to pull his head in while the powers that be ran round writing licenses for the radars and fudging the issue date. The ticket that my colleague received was dropped- but he really put the cat amongst the pigeons.

This newspaper article did make me wonder if they are licensed to operate and basically cause interference on that radio frequency band.

Interesting post and it made me google for the radio spectrum laws. And I think I just found something interesting, someone please let me know if I'm reading this right. Relavent info posted below, T&C #5

2. General user radio licence

A general user radio licence is granted for the transmission of radio waves, by means of vehicular radar short range device radiocommunication transmitters, for the purposes of road vehicle collision mitigation and traffic safety applications, in accordance with the terms, conditions and restrictions of this notice.

3. Terms, conditions and restrictions

1. Except as otherwise provided in this notice, the frequencies and other emission characteristics are those prescribed in the Schedule to this notice.
2. Transmitters must conform to technical standards as prescribed in notices made under Regulation 32 (1) (b) of the Regulations.
3. Frequency use is on a shared basis and the chief executive does not accept liability under any circumstances for any loss or damage of any kind occasioned by the unavailability of frequencies, or interference to reception.
4. The chief executive reserves the right to require and ensure that any transmission pursuant to this general user radio licence changes frequency, reduces power, or ceases operation, where reasonable evidence is provided to the chief executive of harmful interference being caused to licensed services.

EDIT: I guess that applies if they are operating under a general user license. Anyone have the specifics for the Ka Band spectrum license?

meh....if I get a ka on the V1 I always do a brake check.....if I dont see a cop (you can tell by the strength of the signall) I carry on....I think its a good thing if they deem it a black spot, all good..and if they try and hide other coppers under the trap the good ol v1 will pick it up on the counter

Thats interesting Dangerous - I had wondered what the signal from tractors was for - seems a brilliant idea, and sad that NZ authorities have take the "Detectors are only used by hard core Speedsters approach".

If they played fair, I wouldn't need mine...

Na the tractors here don't have SWS what they have is speed sensing radar (K band)

It compares actual speed (radar) to the transmission speed to give the % of wheel slip

Ther's a really cool urban legend about a pair of cops busy speed trapping in Northern Scotland.

Sorry. Look here.
As for "auto release of a missile"...

the only thing it ever detected was falses along with those speed trailers that tell you how fast you are going.

The speed camera vans up this way are hiding their vans in the vicinity of those devices. Attempting to hide their systems in the radar beam.



It is interesting to note that a "drone" refers to a target that gets shot at and destroyed...

Hey I did say urban legend - its still quite a cool story though- sometihing for those drunken evenings around the fire..

I guess in wartime situations there could be some form of auto release - where alerting and firing would take too long. I guess thats how so many Afghan wedding parties get nuked...

Good point a 12g at 10m should do the trick
