Mobile phone jammers

[TheFaQQer]

All they would have to do is move 5 yards to the side and their call would be recieved. The thing will not shut down a street or a village or a town.

Do people remember that there used to be a perfectly good world to live in before nokia.

Phew - all they need to do is to keep moving all the time, just in case some inconsiderate tw@t has put their convenience ahead of the safety of others.

There is a good reason why jammers are illegal.

They are not illegal, please keep up.

They become illegal the moment you switch them on.

That is like saying guns become illegal when you shoot someone, cars are illegal when you run over someone, knifes are illegal when you stab someone.

WHS.

When some thug starts kicking your head in, and people around you can't call for help because of your jammer, you may start to feel that overhearing their conversations was a small price to pay.

And what about the guy in the next carriage who has a heart attack, and the train staff can't get an ambulance ready and waiting for him at the next station?

Sounds thoroughly selfish and irresponsible to me.

So what we really want is a short range jammer, where you just press a button to make the call drop, for only people within, say, a range of five feet.

That way, you won't block people calling for help when your head is being kicked in (perhaps by the thug whose call you caused to drop), and you won't interfere with the heart attack victim in the next carriage.

Sorted.

I did design once a jammer that worked by modulating the mains supply. You switch it on, and it causes an awful buzz from an loudspeakers connected to amps connected to the same supply. Quite useful when you live in shared accomodation for getting the guy who insists on playing Pink Floyd very very loudly as 3am.

Get the frequency right, and you could blow the speaker.

You'd need to find a frequency that Pink Floyd hadn't already tried.

If you are using it (as the OP suggests) on a train, then if you drop the call, then the propensity for them to just blame the train and redial is high.

In order for them to be truly effective, they need to be blocking signals constantly, which is where the situation becomes problematic. I've seen the conductor on a train have to use his mobile to ring the police to make sure they were there at the next station to arrest someone for assault, which if the calls are being blocked, is somewhat difficult to say the least.

Yea, some guy on the train decides to rip someone and the first thing I will do is switch on the jammer. At the same time jim on the next carriage drops from 10 years of bacon rolls. It's all my fault.

You sound like a man who is never responsible for anything wrong.

Just gimme one of those jammers! I promise to use it sensibly
