[net.followup] radar detectors

Firstly, this is my first attempt to reply on the net, so if I
screw up any (helpful) advice will be appriciated.

I have a "micronta" (sp?) xk radar detector which suffers the same problems
common with most cheap fuzz busters.  Stray noise etc often gives me cause
to hit the breaks, (covering one's own ar**)!

Well, over the years I've seen two different techniques described
to "alter" the readings of radar speed monitoring equipment.

The simplest involved mounting a good-sized loudspeaker on the bumper,
with a rubber sheet mounted across the opening.  You were then 
supposed to glue some foil strips onto the sheet, and run a very
low frequency tone through the loudspeaker.

The other technique used a small, bizarre antenna-like contraption that
would be mounted on the car.  You were supposed to run a signal
into this beastie as well.  It supposedly had elements to cause problems
for both K and X band radar.

I've never seen either of these techniques actually tried, nor
do I have any practical experience with any other techniques.  
Out here in California, radar traps are not the same sort of
problem that they are back east.  While radar *is* used from
time to time here, you only rarely see organized speed traps of
the sort typical in the east.  Also, unmarked vehicles may *not*
be used to ticket traffic violators in California (at least
in Los Angeles and on the freeways throughout the state). 
Even more significant is the fact that the Highway Patrol
(our "state police") may not use radar on California freeways.
It turns out that they have been authorized to do so for years,
but the California legislature, mindful of public opinion on this
issue, has consistently refused to allocate funds for the purchase
of radar equipment for the Patrol.

All of which makes me very glad I don't have to try to live in
California.

It turns out that the use of radar on freeways in California and the use of
radar on a street that has not had an engineering and traffic survey done
within the previous five years constitutes a "speed trap".(Also included in
the speed trap definition is the timing of a vehicle between two fixed
points).  Speed traps as just defined are not legal in California.

Presumably the purpose of this law was to require police to actually observe
a vehicle for some time rather than simply relying on a single instantaneous
reading of speed for the purposes of determining unsafe driving.

I suggest that one place a whirlygig of corner reflectors spinning
away from the radar site -- air pressure of motion is enough to drive
this.  The corner reflector is much more efficient a relfector than
your hood, the down doppler of the rotation will take 10-20 mph off
your speed, believable without being too gross.  Besides, it makes a
pretty hood ornament.

And how do you arrange for the corner reflector to spin only AWAY from
the radar site?  what spins one way on one side spins the other on the
other side.  You would have to have the corner reflector cowled in a 
hemisphere which was radar-opaque that aerodynamically convinced the
reflector's open side to spin rearward on the car.  

Note: for smokeys on your rear, you want the device spinning toward
the smokey, likewise to the rear of your car.  Remember, the best
speed traps hit the cars after they pass the measurement smokey
who targets up the tail pipe, and another smokey makes the collar
a quarter mile down.  These use  pulse guns.
