Henry mentioned something about radar jammers. I actually built one of these from plans I got through the mail, almost 20 years ago. It also had a interface that you could hook up to an Escort radar detector. You are correct, they are illegal from the perspective of the FCC. It also was very difficult to get the transmitter antenna as the people that sell them usually deal with other businesses that build radar guns, and dont normally sell them in single quantity.
The drawback to the jammer was that while the jammer worked in principal, it had a couple of flaws: 1) The transmitter antenna was expensive, maybe $250 each (20 years ago!). Ideally the jammer had two for each band, but it could be built with one, and another added later. I could only afford to buy one, so thats how I built it. 2) The Escort interface was buggy, and slow to activate the jammer. If you left it on all the time you would draw attention to yourself from your transmissions. There was a sort of standby mode for the Escort interface, but it was still not fast enough for my tastes. 3) For each band that came out, I think you needed to add another set of antenna. At the time only X band was popular, with K just coming out, so I only built it with X antenna. If you wanted both X and K, and two transmitters each, the resulting box started to become quite large and noticable. Even with just X, it was about 3 times larger than the original Escort detector. So while it sort of worked, it was not that practical. My box also kept breaking down, with various resisters and capaciters blowing. I gave up on it after a few months. It was an interesting project at the time.
