= 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 any 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.
