[net.auto] Radar Detector Test

heliotis (12/02/82)

I'd like to point out that more and more states are banning POSESSION of
radar detectors, so be careful.

	If someone gives you a hard time about having a radar detector,
	just pull out the Communications Act of 1934 which says you have
	the right to receive any radio transmissions (i.e. radar) which 
	you damn well please.

	Although technically this doesn't really apply (for some stupid
	technicality somewhere), it should serve to hassle the cop enough
	that he might just let you go.  This is how a friend of mine
	treats cops who hassle him about carrying a police scanner (which 
	he does have a license for, although many cops don't think that's
	good enough).

	I haven't heard about any states banning these things recently,
	in fact, I've heard the ban was declared unconstitutional in a
	few states.  I 'spose they'll never figure it out one way or the
	other...

   Someone told me that the cops now have radar guns that can mark your speed 
very accurately from a short distance with a very short burst. If this is true
it will make all radar detectors obsolete, because by the time your detector
informs you of the cop's gun, he will already have pegged you. Does anyone 
know if this is fact or fiction? I would really like to know before deciding
to lay out $100's for a detector.
   If this technology does exist, how long will it be before the average
local yokel can afford to buy one?

I understand too that there are now radar guns that emit a very
short burst.  However, you have a pretty good shot at
detecting them while the cop is in the process of clocking
the car a mile ahead of you.  Also, I doubt that all the
radar units in the US will be replaced in the next few years.

I have also heard about using radar guns at short bursts.  However, I
heard that the guns have to be "on" between the short bursts, and that
even between bursts they emit a low level of radiation that can be
picked up by the superhet detectors.  Can anyone confirm this?

	There are two types of radar guns which use a "short burst"
	method.  First, there are the so-called "pulse" guns, which,
	rather than send out a continuous "beam" of radar, send out
	a pulse, read it back in, send another, read it back, etc.
	This radar, while harder to detect than "normal" radar, is 
	still fairly easily detected if you have a decent (i.e. superhet)
	detector.

	The other gun is one which is made by Kustom Signals.  It has 
	all sorts of nifty modes on it, like pulse, ambush, etc., and
	is (or was a year ago) the best gun on the market.  The main 
	thing this gun has going for it is its "processing time", the 
	time it takes the gun to figure out how fast you're going.
	Since most guns send out three or four "beams" and read them
	all back in and then decide how fast you're going, you have the
	following advantages:

		1) If you alter your speed during the time
		the gun is processing this stuff you won't 
		get caught, because it can't figure out how 
		fast you're going.

		2) You should have no trouble detecting the
		radar and slowing down in time.

		3) You get about 2 seconds to slow down.
	
	The problem (for us) with the Kustom Signals gun is that instead
	of taking about 2 seconds to perform the multiple readings and
	calculations, it does everything in about 0.8 seconds.  Thus, if
	you don't hit your brakes as soon as you detect the radar, you
	just got yourself a ticket (chances are you'll get one anyway).

	However, there is one plus to this situation.  The gun (model
	K-55, I believe) lists for about $3500.  Thus most police 
	departments won't have many, if they have any at all.

	I've written this info down from memory, but for those who
	like sources, check the Car and Driver radar detector report
	from last year (not last month's).

I thought it was just me. Cut out the repeats!

\I'd/ like to point out that under the provisions of the Communications
Act of 1934, which governs radio, tv, radar, etc., ANYONE can recive
ANY electromagnetic radiation the choose.  This makes radar detectors and
satellite TV receivers legal, at least on the federal level.  I understand
that in at least one state a federal court has ruled their
anti-radar-detector-posession law invalid for basically this reason, as well
as that one about federal laws taking precedence over state, and even the
interstate commerce act!
