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...

Help!

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!
