Jamming a jammer is a very bad idea. Any kind of jamming can result
in arrest, prosecution, heavy fines, loss of equipment, and heavy
prison time.
Contact your area ARRL Region Manager and advise him of the problem.
Get tape recordings of the jamming. Identify and photograph the
person and his transmitting location.
In some states, legislation has been passed that allows local police
to arrest jammers. Check with your local police department.

It is best to exhaust all possibilities before taking things into your own hands.
That said, a HV transformer (Neon Sign transformer) with a 1" Spark Gap
will lessen his entertainment by providing a 20 to 60 dB over S9 signal
on his receiver.
This will also tend to stop his CB communications also.
The closer tot he offending station, the better. I am sure some of his neighbors will be glad to assist.
One lead to a metal screen, 1" spark gap between another lead to ground. Condensed version: Jacob's Ladder.
A Local TV repairman introduced this concept to the CB Community back in
the 70s. I think he used a flyback transformer.
I know you probably won't be able to implement this for obvious reasons,
but it did the job in the unregulated 70s.

To take this 1 step further, you would need to have the following items:
1 - 12v battery
1 - small solar panel
1 - 12v Ford Ignition Coil (should be able to find in any car scrap
yard)
1 - sm 12v relay (input coil voltage 1.0v - 3.0v) (output contacts that can handle the momentary current draw from the batt to the ford coil)
2 - pieces of #18 ga solid wire (no jacket) (about 12" long)
What to do -
1] Attach 1 piece of the stiff wire straight up from the high voltage terminal (u might need to stuff part of an old ignition lead in there also to make it fit), straight up, attach the other piece of bare wire to a
close case ground screw, and run it parallel to the lead from the HV terminal. They should be approx 2" apart and will make a good Jacobs
Ladder.
2] Attach the 12v to the primary leads of the coil - make sure that you go through the relay output contacts. A simple series circuit.
3] Attach the leads from the solar panel (make them longer if you have to) to the input coil leads of the RELAY.
4] If you want you can mount everything on a piece of plywood approx 2 foot sq, except the solar panel.

Jam a Jammer? Do that and he wins. Simple tactic. Shoot the dogs, stringhim
up by the coax - if he lives jam him with his own antenna!

I would prefer to use a sling shot and shoot a thin wire over his antenna
and just ground it.

No more Mr. Nice Guy.......in
Simply take a set of pruners and cut the NEUTRAL wire to the house.
The resulting electrical fire will be rewarding, will stop the jamming and more than likely destroy the radio he is using.
Heavy motors will stall (refridge) and the smaller items will get over voltage.
If the line is underground, simply toss the dogs some stuffed toys soaked
in Ether or Chloroform, enter the yard and loosen the neutral connections
the
breaker panel....works good too.
This guy is a shitbag, treat him like one.
Send a $25.00 donation in his name with his return address to the Mormons
and Jehovah's Witnesses...
He'll be answering the door so much he wont have time to jam ya...

Theres obviously the sharp-shooter/marksman method!!meter
No, its not what you think. Someone grabs a decent rifle, and taking
very careful aim, can target the masts, and antennas of the offending
station and take them out. This will at least cost him some money in replacing the stuff. Although it's probably illegal to discharge a
firearm in city limits in some communities. :-) Oh well; it was just a thought!
Keep on the trail of recording the jams, also get a group of people
together and make sure you can triangulate everything down to his
location so that there is absolutely no disputing his jamming practices.
If indeed he is on the 10 meter bands then he potentially is operating completely illegally if he has no license, and if he does have a license
then there is the forfeiture issues along with hefty fines, and possible
jail times for the repeated infractions.
Then local authorities need to be notified as well, and you'll need to
see if there is any applicable local laws against the practice. The
local FCC field office needs to be kept abreast of all activity and
attempts to deal with the individual and the situation as a whole. More
than likely, at some point an FCC field office rep will be coming out to
pay the individual a very special visit. I hope it doesn't turn out to
be another Jack Garrison like case for you!

Coax.....why bother. If your going to cut anything, you cut the NEUTRAL wire to the house.

Well, just for starters, next time he keys up his radio it blows the
finals. Working into a dead short don't you know.. He automatically
figures it's something in his radio, of course, so he gets out his
backup and tries again. Blows the finals in that one also. Might take
three or four rigs before he figures out it's his coax and has to
replace it all. You know, that ole thing about a needle in a haystack, well..... coax in this case.

<SIGH> it REALLY doesn't work that way in real life. a shorted feedline
wont always blow the finals.A fairly smart operator will notice the signals are weaker, a lot of transmitters throttle back into high VSWR's.
AND..if the short is close to a 1/4 wave the part of the cable will actually load up just fine.You see (if you knew transmission line theory) it's NOT a "dead short"..but actually a complex transmission line. DC wise..yes..its a short..but then again SO ARE A LOT OF SHUNT FED ANTENNAS....Modern transmission line is SOLID core...look up Belden 9914 or LMR-400..can you push a straight pin thru that?
Try to learn some real theory.....you might be surprised.- Hide quoted text -
