And there in lies the rub.

Every time something is proposed to make them do their
job correctly and legally, they throw their hands up, "But
we can't do our job!" and the assorted unions step in to
block it as well.

The "management" gets involved and finds new creative ways
to distort laws to their own purposes to "protect their own."

This is all very interesting but can anyone please answer my original
question? IE how they work and how it can be legal? Lenny

OK, the answer... 1. They don't typically work, and 2. they are not
legal.

In theory one could build a jammer circuit, that would work with one
specific brand/mdel of radar gun, however such a system may not work
with other brands or models, and as well any attempt would violate
federal law absolutely and many states also have prohibitions against
such devices.


"in theory",one could build a channelized EW(electronic warfare) suite such
as military aircraft use,and it would work with all known radarguns.
Cost would be prohibitive,though. Just fitting one to your vehicle would be
a real Project.

BTW,I wonder if a broadband whitenoise type of jammer would work,burying
the radargun's signal in the noise.
You'd need substantial power and have to cover each band used for radar
speed guns.it could be triggered by the first radar pulse and xmit long
enough for you to pass the patrol car or to slow to posted speed after
being alerted.

Still highly illegal,though.

then there was that guy who made a "stealth" car,faceted like the F-117.
no radar return,no speed measurement. :-)
