- ighway radar jamming by The Jolly Roger
-
- Most drivers wanting to make better time on the open road will
- invest in one of those expensive radar detectors. However, this
- device will not work against a gun type radar unit in which the
- radar signal is not present until the cop has your car in his
- sights and pulls the trigger. Then it is TOO LATE for you to slow
- down. A better method is to continuously 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 my 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 the 5 to
- 10 volt DC and enclosed in the correct size cavity (resonater). An
- 8 to 3 terminal regulator can be used to get this voltage from a
- car's 12v 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 & banks, etc.) contain a Gunn type
- transmitter/receiver combination that transmits about 10 kilowatts
- at 10.525 ghz. These units work perfectly as jammers. If you
- cannot get one locally, write to Microwave Associates in
- Burlington, Massachusettes and ask them 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 weather-proff enclosure behind the
- PLASTIC grille. Switch on the power when on an open highway. The
- unit will not jam radar to the side or behind the car so don't go
- speeding past the radar trap. An interesting phenomena you will
- notice is that the drivers who are in front of you who are using
- detectors will hit their brakes as you approach large metal signs
- and bridges. Your signal is bouncing off of these objects and
- triggering their radar detectors! HAVE FUN!

- P.S. If you are interested in this sort of thing, get a copy of
- POPULAR COMMUNICATIONS. The ads in there tell you where you can
- get all kinds of info on all kinds of neat equipment for all kinds
- of neat things!
