Recently the FCC has been writing to the CEOs of electric utilities about
intereference experienced by individual amateurs and I believe last week I
saw a letter to some people about a baby monitor.

The letters are at http://www.arrl.org/news/enforcement_logs/

That's great. So now your friend has become a part of the problem
instead of part of the solution. That makes him no better than the guy
he's compaining about.

Actually, quite the opposite. None of the neighbors could get any
response
from the FCC. The offending CB'er was coming over the TV's and radios in
the neighborhood.


Commercial TV and radio receivers are notoriously susceptible to
strong signals well outside of their frequency range. The
manufacturers have taken too many shortcuts to provide decent
selectivity. So the FCC doesn't pay much attention to those
complaints.

But as soon as the hams in the area had a problem, they should have
been notifying the FCC. At that point, your neighbor was interfering
with a licensed service and they do pay attention to that. Admitedly,
their attention has been sporadic in the past, but in the last few
years they have gotten much more serious about tracking down operators
that are causing harmful interference, even if they are licensed. If
the event you described happened recently, there may have been a
better way. Keep that in mind if he gets back on the air.

Thanks for your 'help'!

Apparently you are a lawyer (or play one on usenet)?

You don't need to be a lawyer to know the law, nor a weatherman to know
which way the wind blows.

You will be interfering with an authorized radio service. That's illegal.

You will be transmitting (outside Part 15 limits) without a license.
That's illegal.

You will be putting on the air transmitting equipment that is neither
inspected-and-accepted nor type-accepted. That's illegal.

You do not own nor control the airwaves on your property. I could try to
list the things that are illegal even though you own the property they're
done on, except that I have a 10-Meg limit on my temporary file size.

I agree you probably won't get caught, but don't kid yourself about what
you're doing...

This one is tried and proven to be a winner. Start with some kind of mild
spark generator (large buzzer or mechanical bell). Isolate the device from
it's power source with a pair of chokes (and place in soundproof box). Feed
from the device(one lead to each side of spark gap or points) VIA 450Ohm
open ladder line to a dipole cut to the 11 Meter band and orient it in the
direction of the CB'ers antenna. This setup TRASHES AM and SSB RCVRS!!! I'ts
possible your neighbors might see some sparklies in their picture on the low
VHF channels. Want to make it REAL efficiant? take the CB radio you have and
put a COR on it's RCVR. Set it up without an antenna to his favorite
channel.When the COR closes it starts a time relay and transmits for about
10 minutes. Each time it hears the jerk it pops up and jams his RCVR.
This scheme will NOT work over 500 feet. If this guy lives next door or
behind you he IS game. He can not talk with someone ifhe can HEAR them to
begin with. Even the dumbest of animals will soon learn....Eddie

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!

Wieland,
I am not kidding myself. I never stated, asserted, proposed or implied that
jamming was legal.

I am very sorry that you completely misinterpreted my post.

I know that it jamming is illegal, okay Wieland?

Thanks for your help!

a friend made a jammer for a difficult person who caused a lot of
problems for the surrounding world. The jammer had photodiode, and
would only operate when dark, it transmitted only after a CB
transmission - for the next 20 minutes causing reception impossible
for this guy, and it was hidden in a nearby trea

So this bloke couldn't make 2-way communication and after some time
resigned to find a new house somewhere far away from this place

He had caused very much problems running high power and blocking
TV-and broadcast-reception, so it was a good idea to keep him from
activitating the CB or what ever band

It happened many years ago, but still it is told to amuse the friends
