We had the same problem with a local years ago. The guy would broadcast his scanner over the CB local channel hours every day. Thinking that the FCC would be responsible caretakers of the spectrum and enforce the rules behind a situation like this on CB is silly. You would have better luck with the local police or zoning board and complain about interference. When none of that works, Radio Shack sold a simple solution in a small paper back book called "Communications Projects"
In this book a wide band RF transmitter using a transistor, capacitor, resistor, and coil wound on a straw are described. The stock circuit can be enhanced in ways that I will not fully disclose other then to say 60 cycle hum is beneficial here. The device was planted at the offenders location and effectively blocked his ability to receive anything between standard broadcast AM and about 400 MHz. It was allowed to run until the person actually moved 6 months later.
