- HIGHWAY RADAR JAMMING
-
- Most drivers wanting to make better time on the open road will arm
- themselves with an expensive radar detector. However this device will not work
- against a gun type radar unit in which the radar signal is not present until
- the cop has you car in his sights and pull the trigger. Then it is too late to
- slow down.
- A better method is to continously jam any signal with a radar signal of your
- own. I have tested this idea with the cooperation of a local cop and found that
- his unit reads random numbers when your car approached him. It is suprisingly
- easy to make a low power radar transmitter. A nifty little semiconductor
- called a Gunn diode will generate microwaves when supplied with 5 to 10 vdc and
- enclosed in the correct size cavity (resonator). An 8 to 3 terminal regulator
- can be used to get this voltage from a car's system. However the correct
- construction and tuning of the cavity is difficult without good microwave
- measurement equipment. Police radars commonly operate on the K band at 22 ghz.
- or more often on the X band at 10.525 ghz. Most microwave intruder alarms and
- motion detectors (mounted over automatic doors in supermarkets, etc.) contain a
- Gunn type transmitter/receiver combination that transmits about 10 milliwatts
- at 10.525 ghz. These units work perfectly as jammers. If you can't get one
- locally write to Microwave Associates in Burlington, Mass. and ask for info on
- "Gunnplexers" for ham radio use. When you get the unit it may be mounted in a
- plastic box on the dash or in a weatherproof enclosure behind the plastic
- grille. Switch on the power when on the open highway. The unit will not jam
- radar to the side of behind the car so don't go speeding past the radar trap.
- An interesting phenomena you will notice is that drivers in front of you who
- are using detectors will hit their brakes as you approach large metal signs or
- bridges. Your signal is bouncing off these objects and triggering their
- detectors.
- Have fun... Ben Piper
