As the recent holder of a new speeding ticket, also from speed radar. I got
clocked at 69 in a 40mph zone on Lake Shore Drive in Chicago at 1 in the
morning. There was NOBODY else on the freeway. I wascurious as to the
frequencies used for X & K band radar.

Are these government frequencies? Does FCC Part 15a apply to a radar signal
generator (ie jammer)? I know that often cheap radar detectors will set off
one another becuase they usually have a local oscillator that I think
connects to an AM Super Heterodyne Receiver. My pink cloud project would be
to build a signal generator pegged to a radar detector to turn on when
radar signals are detected. However, I do not know the precise effects it
would have on Doppler radar (I would expect superposition of the signals),
but I do not know what the radar gun's filtering systems are.

If this is illegal, how good does a radar gun do. Getting a speeding
ticket, just makes me want to buy one even more now. However, I do not know
wht good it would do, depending on how fast you can *brake*.

PS: I wound up with the NEW ticket system where I am given 3 choices:
	A) Pay $50, Plead Guilty. Goes on Record.
	B) Pay $70, Plead Guilty. Doesn't go on record. Not eligible if
	   you have a ticket within last 12 months.
	C) Request Court Date.

		Well, I picked option B. (Sh*t!)
