One rather crude suggestion was made by my boss once....When you replace your radio, use some two sided razor blades as washers. You might not like the red stain in your car, but that guy will never think about his line of work again!

I installed an "auto page 4000" in my scirocco, and I've found it to work quite well. It has a four watt transmitter, and the smallest pager of simular systems. Cost was $120.00 for the xmitter, reciever, two resonant sensors, and installation parts. The unit automatically turns on every time you turn off the car. I have not yet found the limit of its effective range. It works over a several block distance, and into metal buildings quite well. Hopefully I will never hear the beeper go off when I do not expect it to. I can tell you that the system is great for some peace of mind when you are parked in a bad part of town. I don't know if the auto page is the best system, but it certainly works quite well, and has a good warranty. Keven Boyett tektronix!tekid!kevenb

If I had razor blades to protect my car stereo, I would be afraid that a thief might just decide to trash the entire car for vengance. Not afraid to listen to AM.

Personally, I like tarantulas and scorpions crawling around inside... But one I thought up a while ago might really be worth building. At least, I get a lot of satisfaction at imagining this thing going off for some crook... Take a cheap tape recorder, one of those .22 calibre blanks from stud setters, and one of those small CO2 cylinders from a pellet gun. When the regular car alarm goes off (or whatever), the tape recorder cuts on and that faithful standby, the 555 timer starts counting: "WARNING! WARNING! Cyanide gas will be released in exactly 10 seconds. 10...9...8...7...6...5...4...3...2...1." At one, fire the stud setter blank--electrically, or a solenoid, I don't care--and drive a pin into the CO2 cylinder. I think the hissing should really make the thief's day, don't you?
