Yeah, what is going on with all of these people trying to 'jam' radio signals? I would not waste my time thinking about how to do it or even if I did know, I wouldn't tell anyone. It is illegal, and in most cases immoral, so please find another project!
Here are the requested Schematics you have been searching for. In no way am I imposing that you should actually use these schematics to build and more importantly use one of these jammers. I am only providing schematics at a request. Please be aware that these are very Illegal Indeed and there are rigourous fines if you are held accountable. I'm submiting these for educational purposes only. **broken link removed**
