The FCC found this device was not certified under Part 15, and *could not* be
certified, as its *intended purpose* was to interfere with the licensed police
radar service.

Yes indeed. RMR obeyed the ruling, too. They took that particular model off
the market.

Then, they redesigned the case, changed a few electronic parts, gave it a new
model name and number...and went right on selling it. AFAIK, the FCC hasn't
caught up with them yet.

Its purpose is to intentionally interfere with a licensed radio service. And,
more fundamentally, to allow motorists to intentionally violate the law without
risk of prosecution.

Only problem is, the @#$%^&*ing things don't work. They assume that the cop
can't tell that a vehicle which spits "23 mph" or "360 mph" on their radar,
while passing everyone else on the Interstate, is using a jammer. There may be
some dumb cops out there, but they're generally not THAT dumb. Most people who
plug these toys also don't realize that a cop does not have to write down a
specific speed on your ticket. He or she can legally write "in excess of
insert speed limit here," assuming that is an accurate account of what
happened...rendering any false reading because of a jammer irrelevant.

According to the car magazines which regularly test such so-called jammers,
they only work at such close range (if they work at all) that by the time they
emit their interfering signal, the cop has already measured your speed. The
only radar and laser jammers which really work, you can't afford, and you would
be jailed immediately and forever if you had one...they belong to the military.

Many jurisdictions have invoked "interference with a police officer" statutes
to arrest and jail motorists attempting to use jammers.
