Anybody know anything about broadcasting pirate TV signals?

You can transmit a signal about 1 inch just using the output off of your vcr or cable line, but I'm not sure how you might amplify it sufficiently to be watched in the next house over. If I'm not wrong, TV signals take up some enourmous bandwidth, which means that you need a specialized RF amp to TX. But it can and has been done by some of the 'revolutionaries' like Abbie Hoffman.

Here is a detailed PDF document on a TV transmitter kit.
Ramsey electronics (http://www.ramseyelectronics.com/sitepages/pdf/hmanuals/tv6E.pdf)
If you don't wish to build one, there are quite a few pre-built transmitters however your looking at a bit of money to set a decent one up.
You can make modifications to some existing radio equipment, also wireless CCTV cameras can be used in conjunction with a linear amplifier.
However with TV transmissions, you will need a primary sound and vision carrier. In Australia the primary sound is 5.5Mhz above the vision carrier.
Also with home TV another big concern is the limited range, you will need a fairly decent output in wattage to broadcast large distances.
What are your requirements for the pirate TV setup? And what are we looking at here, a cheap setup to Tx to your friends house over the road or something on a larger scale to swamp the town?

I recall helping a fellow ham set up an Amateur Television station on a field day. Although I didn't get to do much of the technical work, it didn't seem much more difficult than setting up a regular station.
I do remember one thing: the equipment is expensive.

it's imposible to have a pirate channel on cable TV, the only way you can have a pirate tv station is on an antenna tv..Or so i was told.

You are correct (antenna). Just like radio, tv's have a side carrier frequency as well. Slow scan your tv sometimes and you will find interlaced images.

It IS possible to setup a pirate satelite broadcast...

What's to stop you from injecting a signal back into the cable system?

That's what I though.
We have done it in school, but I was unsure about a 'real' commercial distribution system.

lifejunkie would you be able to post more information about how you injected the signal at your school?

It was really simple.
I made an RF amp 6 MHZ wide, tuned around CH 3.
Just hooked a vcr to it and fed the output directly into the cable line going to the tv.
During the video announcements, the last day of my senior year, we blasted the "killing in the name of" video over their signal.
It looked like shit, but is was recognizable and the audio was good.
I'm not sure how the video distribution systems was setup, we just got lucky.
It must of been setup quite wrong, because I'm fairly sure the lines are supposed to have some form of independence or isolation.

The reason is, the TV is receiving 2 signals. You are not injecting the signal in place of the source, but rather trying to compete against it from a remote location.
I really wouldn't recommend doing this as receiving an RF source directly in to the transmit finals from the other output device will result in equipment failure.
Transmitters are built for transmitting, and when you connect it to the cable to transmit your signal, you will get a signal injected in to your TX finals.
This will cook the RF amplifier you are using to broadcast. It's the same as connecting 2 CB radios with a piece of coax cable and transmitting on both at once.
If i didn't make much sense explaining that, it's because over the last few days i have driven miles across the state, gone to a funeral then driven home and i'm sleep deprived amongst other things.

In reply to BBB I am looking to "swamp the town" This interest is purely academic... at the moment. I would like to know if transmitting in the AM band is possible, if you get me, one of the things I am looking to do is bounce the signal off the atmosphere. Also any info on satallite piracy would be cool. More technical specs and sources of equipment would be cool. I would like to be able to tune in on a specific frequency and over ride it within a mile or so of my broadcast. I have seen devices that do this on a small scale with FM radio.

There are dozens of ways to do this. If you want to "swamp" a TV signal transmitted via the air, you could overpower their signal. The effectivness of this depends on a few factors.
The distance from your location to the real transmitter. The further away from it the more you will "swamp" the surrounding TVs.
Also the more TX power, then the stronger your signal. A high db gain omnidirectional aerial and a low SWR will help get that power out there.
Remember it needs to support the primary sound and vision carrier at the frequency you want. This setup won't "take over" the entire airways, just swamp the surrounding area.
Another way would be, most TV transmitters have some kind of uplink, whether it be Gigahertz, Microwave or Sattellite. Usually the transmitter is on a mountain or tall building, and it is linked to the TV station via an uplink.
You could find the uplink frequency, then set up your equipment near the TV transmitter and overide it from there. This would then be rebroadcasted through the tower.
For a transmitter you could modify a color CCTV camera, the type that you "tune in" to a normal television. Then run it through an amplifier.

It's not really done with frequencies in the TV range.

"Overiding" requires more power and closer proximity to the audience then the source. Thats why most pirate stations choose their own clear frequency, and gather an audience from there.

How much would it cost to buy a kit(minus antenna) to broadcast pirate TV in about a 2km square area?
Or, could I get plans to build a cable interjecting one? Becuase I know on cable, channel 41 is not used.

Hi everybody i'm an idiot.
I disguise Pornstarguru.com links pretending it's related to Radio Free America.

I would be interested in learning how to broadcast over a range of about 10-15 killometers if possible. their is a huge commercially used antenna about 4-5 killometers away from my home. I want to blanket my town with my signal so I can broadcast whatever i want. But how would I go about this? How much money would I be looking at? just curious is all....

How might one go about doign this?
what, out of all the people on this site, no one is willing to give information on sattelite pirating? interesting.
you could rent a satalight for $500 per hour bu that was a long time ago so i dont know now maybe you could use one to do some pirate

this thing about cable you wouldn't be able to do it i think ok the only thing i could think of (iam only learning)is i have a dish that i point at the foxtel sat and get free foxtel with a foxtel decoder. what you could do is find where the nearst sat is to you. find some that works for what ever cable you want and knows how there stas work and get some info from them.then trans to the sat you would have to hack some thing a long the way and you be in big shit if you got court. i know fuck all so don't say i suck just thinking aloud
