I once worked with a electron nerd who heavily modified a CB radio to trigger the flashing white emergency vehicle (RELCO or RADAR-Light) traffic intersection lights. He succeeded and even connected it to a linear amp, tripping dozens of lights in the town. It cause a major accident at one large intersection. He spent time in jail for that caper. He also made an FM bug that spewed a heavy harmonic onto the police band, interfering with a TAC channel and also built a 60 watt AM transmitter on the 7mHz shortwave band playing music all the time. It involved the FCC and he received jail time under work-release pgm. for several months for that as well. He was quite smart and insightful, but socially retarded, lacking common sense!
