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. 73 from Rochester, NY Jim "Limitedselection" wrote in message ...

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. -- Leland C.

"Spoken like a true jammer himself" 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? |

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? |

To me trying to jam someone instead of potentially costing them a lot of money in repairs is actually being rather nice. 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? 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. 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. 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. LMAO. Regards, Peter. |

Can't those activities be considered. jamming via a keyboard? 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. -- Leland C.

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. -- Leland C.

"Limitedselection" wrote in message . ... 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! 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 C.

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. -- Leland C.

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. Damn, that's one fast car I must own. |

He might be experiencing mental difficulties, or he may just need bigger shoes as they seem to be crushing his brain, in his little toe. /quote I passed the test and followed the link to the main page.
