Question about choosing a mobile phone jammer circuit

Probably about as effective as the published plans on how to crack encoded cable or satellite TV ;-)

Since you "don't want to hear about legal issues etc.; I gladly accept responsibility for illicit use of such a device", good riddance... enjoy your time busting rock ;-)

An otherwise normal friend of mine is positively unbalanced on the topic of public use of cell phones. He spent $300.00 for an illegal handheld jammer which apparently consists of a black box and a button. My phone blows right through it which I gleefully demonstrate to him at every opportunity.

There are a number of plans here:

Can someone comment on the potential effectiveness of these, so that I can choose which one to build? I'm interested in a range of just a few meters, so that I can block the rude bastards yakking loudly on the bus that I have to take every day. I'm located in Canada, so I'm assuming that frequency ranges are the same as used in the US. Please, I don't want to hear about legal issues etc.; I gladly accept responsibility for illicit use of such a device.

The OP has no balls. He wouldn't dare tell two people on the bus to quiet down... he might get hurt. Such a wimp.

This comes under the heading of requests like: "Can you get my microwave to work with the door open?"

I agree with what another poster said about the OP being unlikely to "accept responsibility".

Can't we all just get along?

Take a hike down to the drug store and buy a pair of earplugs. They're effective, they're legal, they work on other intrusions, they won't get you beat up when the big guy catches you interfering with the call to his dealer. mike

Actually, you aren't likely to take responsibility.

You plan to do something illegal. You are hoping you won't get caught.

It doesn't matter that you are interfering with someone else's legal right.

It doesn't matter that you could end up interfering with an emergency call.

It doesn't matter that you likely don't have the ability to build something that won't interfere with other radio services.

It doesn't matter that you think just because someone is talking on the phone that it's somehow different from two people on the bus "yakking" away. WOuld you tell them to keep quiet? Not likely, because you'd either think it's impolite, or simply because they aren't on a phone it's less obnoxious to you than someone on a phone.

None of this matters because you think it's okay to break the law for your own convenience.

If you were willing to take responsibility, it wouldn't be to knock out someone specific, it would be about something quite general, and you'd break a law to make the point, at which point you'd be quite willing to pay the fine and/or go to jail for the cause.

Another option is noise-cancelling headphones. Go to work in totally silent bliss. Manufactured by Sennhelser, Bose, Creative and Sony.

As for the illegal stuff, who hasn't smoked pot, driven over the speed limit, driven while intoxicated, not paid their due taxes, not handed in money found and so forth.

It's been my observation that governments tend to impose the largest fines for offenders they can't catch.

Cheers.

OK, I should have been more specific: I'm willing to take responsibility for the risk of being caught. The risk is, for me, acceptable, given the potential benefit to me of a working device.

As for interfering with other services, I said I need a very short range, just a few meters. I can easily see if it's interfering with anything else by whether I'm interfering with the bus radio.

I don't see what made most of the responders to waste their time posting here, given that they very well know their comments will not be heeded, as is clear from my original post.
