Here is an interesting idea. A guy could use a 555 timer chip to make a
circuit that would literally key up in the guys face every time he keyed his rig, by connecting the trigger input on the timer chip to the signal from the s-meter , which is filtered dc. the amount of time it would key up for could be set by the timing interval of the chip . Now, we simply turn the sensitivity of the receiver down, and turn the power output down also on transmit. this means a 12- volt car battery could run this setup for a loooong time. The receive sensitivity is turned down until only strong local signals produce enough s-meter output to trigger the chip into keying the rig up. This ensures that it only keys on him, since you will place this somewhere near his residence. A friend of mine did this with great success, since he took a regular breaker box, and mounted it on a light pole near the guy's house, along with a bunch of other boxes that were on the pole already, and ran a 9-foot wire up the pole. It was quite a while before the power company discovered the 'superfluous" box on the back of the light pole, long after it had served its purpose well. the 12- volt car battery that ran it lasted over a month with this setup............. total cost ? it might have cost two or three dollars to make the circuit on a piece of perfboard...

I want to effectively "jam" CB reception on my property. The "jammer" would need to be low power and cover an area about as large as a 'small' city block. I have searched google, but I have only found references to schematics that were either posted to usenet as a picture (thus not saved in google archives), or located on web servers in domains that no longer exist. Any information would be appreciated! |
