circuit diagram for phone jammer - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

Many of us who read and respond to these forums work in the communications industry. We've invested time and
effort in order to make universal communications possible and affordable. We believe that communications makes
understanding between individuals and cultures better.
Now you want someone to provide a circuit to negate
all that work.
If you are indeed a student, you need to tell your professor that jammers are antisocial and

I beg to differ. I work in the hospitality industry and i find mobile phones a pest. The are
loud noisey one way conversations, not to mention the potential ramifications of using them while driving a car.
Phone jammers have become a neccacary part of life. If ppl could use the phones in the correct way, and not annoy
others, then it would not be an issue. what happended to the old days when you could eat in peace or watch a movie
without some obsurd ring tone blaring out. you may work in the communication industry, but try looking outside
your own self centered egotistical view of mobile phones. They are good and very helpful, but have become an ever
annoying part of society... i say jammers for all... If you cant turn your pyhone off in a plane/cinema/hospital/restaraunt/church
etc..., you dont deserve to own it!

If you are annoyed by someone's improper use of a cell phone, *ASK THEM TO STOP*!
Oh, you're too shy/scared/inarticulate to do it, and must resort to jamming not only the person with the cell
phone, but others nearby? Sorry, that's cowardly.
But direct contact is the only way that people will learn
about the bothersome nature of their activities.
Or perhaps they're PAYING GUESTS who are annoying you as
an employee, but your management says not to bother them. In that case, you need to decide if paying guests make
your life supplying those guests with services so miserable that you should change jobs?
"necessary"? Do annoying conversations rise to the level of endangering persons or property? Jamming can stop or
delay contact with emergency personnel - and that does endanger persons or property.
I don't idolize
misusers of cellphones - indeed, I don't own one, and have never worked for a cellular company. But cell phones
indisputedly improve public safety. "Jammers for all" - you would claim for yourself the unilateral right to halt
others' communications, even without talking with them directly. Nope, still doesn't fly: the attitude that you
can affect other people with impunity by jamming is at least as arrogant as that of the users who affect you with
Do it the right way - talk with those who offend you. Your problem is a human relationships
problem, not a technical one.

Obviously neither side has completely considered the opposite opinion.
For those opposed to cell jammers,
concider this. A study found that about half of all middle school students make a habit of carrying on
conversations in class. Someone mentioned that it should be as simple as asking them to stop. Wrong. In this case
it is not an option. Due to Columbine no teacher is allowed to even ask a student to turn off a cell phone. The
reason being, in the case of an emergency, it would be necessary to use it. This is perfectly acceptible. However,
what if it were possible to temporarily susspend a conversation. The key term is temporarily.
For those in
favor of cell jammers, concider this. The cell phone industry is a multi million dollar industry. We live in a
capitalist society, and while cell phones are becoming increasingly annoying and dangerous, it is not possible to
simply limit that industry.

At my daughter's
graduation ceremony there was a guy yakking to his friend on a cell phone near us. My wife asked him to please
move away and he told her to go somewhere else. Then I stepped in and told him to turn the thing off and show some
respect. He got in my face and told me to shut the f*** up......then he shoved me, so I punched him in the face
I WILL NOT TOLERATE THAT KIND OF RUDE BEHAVIOR....so I am going to buy a cell phone
jammer.......until these people learn some common courtesy.....not very popular these days, I know. If you can't
behave like civilized people, you forfiet your right to use a cell phone.
I don't know what to call this guy in
PC-speak, but he was a Puerto Rican..............thanks to the multiculturalists for forcing us to accept all
aspects, good or bad, of other cultures; a fast-track to making the USA a third-world country.

please think wide , open your mind.
A lot of terroristic attacks are performed with
explosives triggered by cellular phones. A cell jammer will put you on safe side because nothing will be possible
to trigger anylonger....
I have made 3 of them and they work fine within 30 to 50 meters.

Jamming mobile phones is standard practice in the UK following
terrorist attacks. Its also commonplace in secure areas such as prisons, government buildings and in places of
Jammers are required in these cases to prevent loss of data or simply because the underclass do
not know when mobile phones are inappropriate (e.g. in a Church).
Some health clubs and so on use them
And because the underclass tend to react violently to requests to speak more quietly (they all shout,
presumably from years of shouting to get their views across), its best to resort to subterfuge. Its not cowardly
at all. People get stabbed and shot for this kind of thing all the time.

You can buy yhem pre-made on many web-sites. Noone here knows how to

I think that everybody
that has posted negatively on this thread knows how do to a jammer.
There are two issues here:
do not like the idea of jammer being developped for general use, and therefore are unwilling to contribute.
Some do not like the attitude of people comming and asking for complete design schematic without even
contributing to the discussion, specificly when the request comes from students, in which situation doing such a
project would be considered as cheating and deserve the absolute zero as a mark.
I am from the second
group, and therefore even if I can see some ways to perform this task (probably not the cheapest one), I will stay
