schematics wanted - "jamming device"
 

Help!

I am looking for schematics for circuits to "jam" TV and CB reception.
I am interested in "jamming" reception on my property only, so the "jamming
device" needs to be really low power - only capable of "jamming" an area about
half the size of a 'small' city block.

I read about a circuit that transmits white noise from something like 25Mhz to
something like 30Mhz - effectively "jamming" reception. Any pointers?

I also read of a circuit that used a crystal detector and would only "jam"
after detecting a transmission! Anyone have any info on this?

The closest I have found so far is a reference on Google (dejanews) to
"s_jam.jpg", but there are no pictures there, so I cannot see the schematic.

Any information, schematics, or pointers to web sites would be greatly
appreciated!

I'd never suggest intentional jamming. Of course, if you happen to have a
gasoline powered lawnmower and a 9 foot section of bell wire happened to
land on the spark plug (stripped end on the plug) and the other end on some
insulator such as a clothes line ... :) That would take out quite a bit of
spectrum around 27 MHz (likely 4 MHz either side) for reception for a few
blocks. :)

Not recommended, of course.

A picture and text will be posted on alt.binaries.radio.pictures
Look for "Jammer"

Not of my authoring. I just saved it for future use.

Just remember what goes around comes around. You
jam somebody else, then they find out who and do
the same to you. Its people like you that made 11m
the mess that it is. If you don't like what's
going on on the air then report it to the FCC
field office, or now more recently to your local
police. The local PD now has the power to
investigates cases of illegal CB operations and
take action against the operators.

Tell me......Just what is it that you and many of your
amateur buddies do on this newsgroup with much
regularity? Can't those activities be considered. jamming
via a keyboard?

Leland,
I posted asking for a low-power CB jammer schematic - actually here is a quote:

capable of "jamming" an area about

Your reply to me asking about a device capable of only jamming signals on my
own property is WHAT GOES AROUND COMES AROUND?
What does this mean? That after I jam myself I might get mad at myself and jam
myself?
I am willing to take that chance!

Thanks for your insightful advice though Leland!

I would much rather have someone jam me than pin my coax. I like to think that
other people feel the same way.
To me trying to jam someone instead of potentially costing them a lot of money
in repairs is actually being rather nice.

Plus he missed the fact that the post he was replying to was asking how to jam
CB signals on my own property! I am afraid under these circumstances his
veiled threat 'what goes around comes around' holds no water - as I happen to
know that I will not retaliate against myself.

ASSuming for a second that I did not know myself as well as I do and I in fact
did end up jamming myself back as a sort of revenge - it wouldn't really
irritate me as I had started it in the first place and deserved to be jammed by
myself.
I mean - what goes around comes around, right Leland?

I doubt if they would see it the same way. Have you heard how p*ss*d off
CBers can get at being "keyed over" or jammed? You also suggest TV
blocking... have you ever had to deal with a woman who has had to miss her
favourite soap opera?

I don't get it... are you actually trying to block signals from your own
receivers?
You would be blocking signals with another, stronger signal... so you are
making the receivers useless while it is on.
I fail to see the point... unless, although you own the property, someone
else is involved in some way. If it involves a second person in any way,
they could decide to either report it or do the same back to you.

There is another problem. To be sure to block signals fully, you need to
create a signal stronger than any being received. You cannot fully block
signals in a selected area without some signal going beyond that area. The
signal cannot just travel so far, then stop dead... although the CB DX rule
seems to suggest that someone thought they could.
Unless you have plenty of land around the area being blocked, you could
easily interfere with people outside that area being blocked.

LMAO.

It means Lelnad is a troubled, individual that

Lelnad is full of off-topic advice,...threats, too.

That kind of "jamming" requires the insertion of
the
keyboard in the victim's mouth, or using it to
bust the fingers
thus precluding the victim from typing. 8-) Other
wise it doesn't
do a darn thing.

Radio waves don't stop at property lines, or
country borders etc. To do what you want with any
degree of success without jamming somebody else by
accident requires a rather elaborate antenna
system, and RF power control, that I seriously
doubt anybody has, or can afford, outside of a
major government agency.

You my be willing to take a chance but I doubt
that you're going to be successful in keeping the
jamming signal totally confined to your property.
And that's where the problem starts, and the point
I want to make. People along side of your
property, or driving by, may experience the
effects of your jamming and take action in kind
against you. Also don't forget that when the skip
is in it doesn't take much power to span miles
across country. Major government agencies have
tried to jam signals from the likes of VOA etc in
Cuba, the old USSR etc. The side effects have been
that countries adjacent to the ones doing the
jamming also experienced jamming to their local
signals as well. So if you're going to jam. well
you had better be willing to take the heat from
the unintentional jamming that will occur as well.
And of course jamming isn't legal either.

Thanks for your insightful advice though Leland!

Just some points for you to think about is all.

Leland,
Well, I certainly wouldn't want to cause an international incident!

Thanks for the info.

It means

The little twisted figure, dressed in his flowing
black robe, hood pulled low hiding his Trollish
features from the assembled multitude, clutching
the well worn cross around his neck, feeling
embolden by it presence, with his hatred winning
out over reason, and pointed his tiny twisted
finger at the innocent victim tied to the pole in
the middle of the wood pile and cried out for all
the world to hear;

"I pronounce you an evil Witch just because I said
so! Burn! Witch! Burn!"

The crowd stirs, and people whisper that somehow,
somewhere, this madman, this self appointed
apostle, a trollish monster disguised in the robes
of virtue, with delusions of Witches everywhere he
looks, must be stopped before he has a chance to
exercise his demented version of hate, presented
as justice to the uninformed, by denouncing others
in the local community, that cross his path, to
satisfy his insane thirst for more victims at any
cost.

9. Show evidence to back up that claim, which you got from the same, sad
source as the "Brummy" claim. Post under one of your other names, if it
makes you feel better about your "killfile".

That source would be the person who claimed that I posted messages from my
home (Peak District), then London, followed by Birmingham, before returning
home to post again... all within 3 or 4 hours.

Moped that site was made by Brainbuster, do a little searching of the web
