NEED: Schematics for building a broad band frequency jammer (FM 88M-108M)

[filesiteguy]

Well...
Thanx all who tried to help me in any way
The whole "story" is:
The main problem is the guy I'm dealing with...He is a mentally ill
guy, that has been freed from a madhouse about 3 month ago. He lives
in his 14 room yard (yes, he sleeps there too) and has conflicts with

So, it is very simple. Figure out what station he's listening to,
setup a transmitter on that same frequency (this isn't hard), adjust
the power, so it goes for at least 100M, and broadcast intermittent
messages.

Tell him things like, "you need to go to sleeeeep...." Or maybe,
"they're coming! quick, shutoff the radio!"

If you have plans for something that would help me achieve my goal I
would like to hear of it. My electronics skills are advanced (I've
used to build and design "bugs" for many years, I own a good equipped
lab, enough that I could build a project.
I have some experience with rf broadcast circuits.
The proximity of the offending radio's location to my house is quite
near so I don't believe a transmitter with an overly large
power...something between 3-5W
will be enough...LOL....

Not to recommend that you break FCC rules, but you probably would get
minimum hassle using VCO. Note that 3-5W might get a few people you
don't want to get.

Get high-speed VCO that can cover your range, then drive the input
with another oscillator that causes the VCO to step sweep over FM
band. Or, instead, you can drive VCO with D/A whose input is PRNG.

But if you really want to get clever, get digital FM receiver chipset,
VCO, etc, and make a circuit that allows you to force your neighbor to
listen to the station you want him to listen to, by taking the output
from the tuner and regenerating it in a spread-spectrum fashion,
pausing at each allocated band just long enough to make your station
detectable. Of you use mic or line-out of computer with "disturbing
sounds on hard disk" to be replayed....

Or you could just knock on door and use oldest analog device known to
man - the mouth.

No, maybe it's not ok, but it may be very effective
(No offence ... I know that those are serious NGs, with serious
members, with lot of ethics and high morality... I feel like I'm
dealing with "alt.saints.xxx)

 

[Nina]

Thanx for the ideas, I'll try that right away


The second part, the analog "device" .... I've tried it several times
before, you can believe me that it's easier for me to ask him...if
only he has been a normal person...but he is - as mentioned before -
insane, mad. He never even answered to my request, and believe me,
I've been as polite as I could. Never tried to argue with him, or
trying to offend him. Just asked him to lower the receiver's volume so
we can rest for a while.
Now I have to close all my windows and use air condition 24/24...

I would like to build a broad band frequency jammer for the FM
broadcast band. I have neighbors that like to play that damn music too
loud all day long. I figure if they turn it load and their station
goes off the air for a while they might get the message. ;-) :-D
If they keep the volume at a respectful level they will be allowed to
listen to their music as they wish as long as I don't have to listen
to it at uncomfortable levels.
I know this is entirely illegal and don't care about it. This is war
(!!!)and I plan on winning.
If you have plans for something that would help me achieve my goal I
would like to hear of it. My electronics skills are advanced (I've
used to build and design "bugs" for many years, I own a good equipped

The proximity of the offending radio's location to my house is quite
near so I don't believe a transmitter with an overly large
power...something between 3-5W
will be enough...LOL....
I'm "jamming" this neighbour with a 5W transmitter, but have to change
the frequency MANUALLY as soon as he changes the station, so I cannot
figure out how to do it automatically...
I'll be VERY THANKFUL for your help and ideas
TIA

Wow people !!!
I'm feeling now as a killer !!! I'm breaking the laws !!! I'm not a
honest person !!! I'll go to HELL !!!
The police is near to my door with sophisticated devices - just to
catch a criminal...Ben Laden is a kid for me... what else ??????????
I've just asked for a simple idea or schematic - and I've been so
blamed I'm afraid to look in the mirror...
When I asked your help I did it AFTER trying all other options you
wrote, AFTER being polite, AFTER the involvement of the law...
Maybe my reqest sounds stupid or maybe I AM STUPID, but I'd like to
see any of you my friends in my situation, without resting time even
in holidays, withot any help. After suffering all day long without a
posibility to open a window in the house...I'm almost sure that if
anyone of you would be bothered day and night by a lunatic, without
any chance to get help from anyone, even from legal authorities -
you'll loose the "polite" word from your lexicon...
What I know is I won't sale my house, and I'll fight back.
Even it's not legal...

Sometimes what we ask for isn't what we really want.

Your real objective is not to build a transmitter, but rather, to stop
the noise, am I right?

Seems to me that if you were given two options, one of which could lead
to a hefty fine and possible prison time, and another that wouldn't,
you'd surely prefer the safe option. But maybe not.

If you do succeed in building a suitable device, you must be sure he
never able to establish that you're behind it. These kind of people
often experience persecution mania at the best of times. You don't
want to be an obvious identifiable target for all those years of
suffering he believes he experienced through being persecuted by
others and have him believe that you're in league with the 'dark
forces' that have made his life a misery.

Here some options I would recommend:
1: Find an old grandpa with a HAM radio setup and old high power HF
amplifier. Pull a wire across your yard (dipole) and hook it up to the
antenna tuner and the amp. Then let the old man ragchew with his buddies on
the air while he is overdriving the hell out the amp. This will produce very
high rf and interference, will get picked up in this stereo speaker wires
and will make the loudest noize possible. The best part this is LEGAL and it
will jam his radio alltogether making it unusable even listening to a CD...
If someone shows up complaining about the interference, you say that we
got the amateur radio licence (that's why you need the grandpa) and thell
them to get the hell out!!! Then there is nothing that FCC can do either...

2: Wait before he turns the volume up as high as possible and then take
your transmitter and feed it with very high level of 30-60 Hz sine wave.
This will most likely blow his low frequency speakers out leaving him with
no stereo to listen to...

PS: Don't take all the blames from these fuckin "legal" people to personal.
Just think that they have no life...

Have Fun...

Or maybe - "Kill your family now - Satan commands it!"
Alternatively, play some music back in his direction.
Possibly with some near ultrasonics added.

Right, my real objective is not to build a transmitter, but rather, to
stop
the noise, you are right. So, I have 2 options: to continue hearing
the noise all day long, to be a prisoner in my own house (I wonder if
in prison the prisoners have to close their windows in their
cells...), or to go to a real prison to find it out....
It seems to me it's the same option, just changing the name.

Meantime, as I wrote, I'm using from time to time a mini-bug, very
effective...

 

[Squinch]

OK guys,
Thanx meantime for your responses.
Not getting much help...
I know it's illegal, I know it's dangerous, and I know that I can build a
huge wall between our houses....
But, I'm still interested to build this device, for reasons that I cannot
mention here...
If anyone wants to help me, please do, but I don't like conferences about my
skills, or legal advices etc.
TIA to anyone who actually tries to help

Do you have a schematic of your transmitter you could put up somewhere ?
That would help with varying the frequency.

[Rich Grise]

Well...
Thanx all who tried to help me in any way
The whole "story" is:
The main problem is the guy I'm dealing with...He is a mentally ill
guy, that has been freed from a madhouse about 3 month ago. He lives
in his 14 room yard (yes, he sleeps there too) and has conflicts with
all authorities, including police. He's arrested from time to time for
violence against his wife or children or neighbours, but released
after a few hours, as he is - as I said - insane, and the authorities
are powerless against him. He is really ill, but not stupid. He lowers
the volume between 14:00-16:00 and from 00:00 up to 06:00. Lower, not
closing...
Our windows are about 10m from his yeard, so you can imagine...
I've considered all the suggestions some of the members gave, as
others have said, jamming his radio could get me into serious
troubles, and changed my "jammer" with a 50-100mW module...It has
about the same effect.

If in fact, the man is ill, that exacerbates the disservice you'd
be doing both to him, his family, the neighbors, and yourself by
simply making jamming noises. That's the response of a spoiled 2-
year-old brat.

It's not your responsibility to help him with his mental problems,
but the adult thing to do on your part would be to be civilized
about it - if you can't talk to the guy in a civilized fashion,
find some neutral third party, maybe a clergyman or something.

If he's doing violence against his wife, sadly, it's her
responsibility to charge the guy with battery and make it stick -
it's irrelevant how sick a person is, they "should" still be
accountable for their actions.

And violating noise ordinances is actionable. If talking to
him is ineffective, then file a formal complaint, and if it
doesn't do any good, then file another, and keep it up
until "they" do something about it. If a couple of years
go by, and you have documentation of being blown off, then
go to the attorney general and sue the pants off of everyone
involved.

If it really comes to that, you might have to hire somebody
with credentials to come out with a sound level meter - but
document, document, document. Leave a paper trail.

Of course, don't do any of this crap if in fact you know
that you're wrong and are simply overreacting to normal
neighbor noise.

Good Luck!
Rich

Thanx a lot for the "compliments" Mr. Rich. You helped me a lot !!!

 

[Lady Chatterly]

The facts are, that's as close to a compliment as I'm about to dispense
to someone with a "****'em I'm gonna break the law and be even stupider
than the insane guy!" attitude.

Are you sure you are about to dispense to someone with a fuckem you
are gonna break the law and be even stupider than the insane guy?

Anyway, I've stopped to break the law...I haven't got much chance
break it, as the guy got the message very quick and stopped to nag for
three days...
....so I've been rehabilitated....Even I'll be a repentant if you
wish...

Wish you all - all the best
