Tracking Down the Channel Hog
Raj A. Narayan
I figure this newsgroup is the best possible forum to get some advice
on this subject.
In the Toledo area, we have a channel hog who hangs out on channel 19
and does nothing but broadcast inane chatter for the purpose of annoying
everyone. Naturally, on 19, we're listening for traffic conditions, so
we lose a lot by just switching channels to avoid this jerk. If you live
around this area, you'll recognize this dude because he closes every
transmission with, "you know what I mean."
While I don't believe in vigilante justice, I do wonder if anyone has
any experience with the equipment required to track someone like this
down. If we broadcast his license number or (if he's stationary), home
address, I think he would probably consider getting off the air. Any
thoughts on this?
Naturally, ignoring these jerks is the best you can do, but I'll suffice
to say that he is persistent enough that when he's on the air, no one
else can even get a transmission through. I'd hate to think what would
happen in an emergency.
Thanks.

Ah....another radio Rambo lives and breathes. Although there is
direction finding equipment available, I have had very good success
with finding trouble makers by just using a good mobile radio setup.
The Radio must have an RF gain control, and it helps if your mobile is
not directional. Just by talking to some locals, you should be able to
get a good idea of where abouts his signal is the strongest. Start in
this area, and set your RF gain so his signal is about a 9..or 5 if
it's not strong enough for a 9 yet.
Take of in one direction. Shortly you should see either an increase or
decrease in his signal. Increase means you're getting closer. If it
starts to fade in awhile, then a 90 degree turn is in order, watching
the meter again for gain/loss.
It's important to keep adjusting the RF gain to a constant when you
change directions, removing your memory from the equation. (nothing
like forgetting where you started)
As you approach, and his signal gets stronger, eventually you will
reach a point where you can no longer keep his signal below full
strength. At this point, look to the sky for the Ariel....and if there
are more than one in the area, removing the coax from your radio will
allow you to pull up near the culprits house with near 100%
verification.
Remember to do all of this covert, do not announce your intentions...
I have wreaked havoc on "signal tracers" when they tell me they're
going to find me...by either turning my beam, going to my standby, or
increasing/decreasing my power.......

A well-placed pin in the coax will do wonders. If that doesn't provide lasting
results, the next step is to combine a long piece of heavy rope and a
grappling hook.

Here it is,
From my previous post last three months, about how to make your own
tracking antenna. (I noticed that Copper Electronics has dropped the
good old Gold Line Signal Hunter antenna from their catalog and online
catalog. Does anyone know who still sells it?)

Amor Powers' Famous CB DF Loop Recipe:
1. 28 inches of #10 insulated copper wire
formed into a circle.
2. Solder a 30pf trimmer variable capacitor
between the two ends of the 28 inch wire loop.
3. 10 inches of #10 insulated copper wire formed into
a circle.
4. Solder coax inner conductor to one end
and the shield to the other end of the 10 inch loop.
5. Tape the two loops together onto a 2 foot section
of 3/4 inch PVC pipe, forming a big loop with a
little loop in the center of it. It should look
something like a big lollipop when you are finished.
6. Hook up the coax to your receiver and tune the
trimmer capacitor for max signal on a local
weak station.
7. Note: there is no metal contact between the
large loop and the small loop, only electro-
magnetic coupling.

you can track the idiot down yourself by watching your RF meter on your radio,
it's a game called cat and mouse or fox hunt and it's better done with a group
of your friends with radios. When you do find him, there are several things
you could do, either bring his address to the attention of the FCC.
OR.....Broadcast or threaten to broadcast his address OR....(my personal
favorite,) sneak on his property under cover of darkness and shove a safety
pin through his coax(make sure you get the center conductor too) and then clip
off the ends so it can't be seen. His SWR will skyrocket! If he notices the
SWR, he'll have some down time trying to find the "short" in his system. If
he doesn't notice his SWR...He'll burn up the finals in his radio and you'll
have PEACE at Last....

YOU BE CAREFULL TOO!!!
There was a guy who put 120vac on his metal grabage can to prevent the
neighbor's dog from thrahsing it. Another neighbor's little girl put her
bicycle on it and she got electricuted. She died and he spend 15 years in
jail.
Thanks for listening,

In the past I have built units that have been inexpensive and worked
pretty well. They consisted of a 1kc audio oscillator, usually rc type
twin t or phase shift, based on a single NPN transistor (2n2222), which
was coupled thru a capacitor to a reverse biased cheap diode (1n4002),
which was part of a resonant circuit of an rf oscillator (2n2222) that
had its center frequency on the offender's monitor frequency, followed
by a buffer amplifer (2n2222) to reduce antenna loading effects on
oscillator frequency and to increase radiated output power. The audio
(1kc tone) would cause the diode's capacitance to change, causing the
oscillator to frequency modulate at 1kc. The deviation depended on the
variation in the diode's capacitance, but I could usually get at least
70 or 80 KC. (that's 7 or 8 cb channels). As the signal is swept thru
the if passband at an audio rate, it sounds like an AM tone is being
placed on that channel, but when the person changes channels, he finds
the same tone there also. It is possible to wipe out his entire
receiver, all 40+ channels, with the right choice of diode to use for
the FM'ing.
The above method is good for plugging ears, but has no effect on
someone who transmits to purposely 'jam' the frequency, or in the case
of someone on the west side of Chicago, who broadcasts tape recorded
obsenities using an endless loop tape, jumping from channel to channel
randomly and never even trying to listen....
I believe I have a better solution. It consists of a simple broadband
amplifier and simple diode detector, and a simple 1 or 2 transistor
(2n2222 again) FM transmitter tuned to TV channel 2, 4, 5, or whatever
low-band TV channel is popular in your area. When the offender keys up,
the signal is detected by the diode detector which triggers a cmos
schmitt trigger that turns on the power to the TV transmitter. The
offender's audio is detected by the same diode detector, buffered by a
2n2222 and used to apply an audio frequency voltage variation on a
reverse biased diode again. The reverse biased diode FM modulates
(actually overmodulates) the TV transmitter that was just turned on by
the schmitt trigger ckt. The overmodulated TV transmitter wipes out that
TV channel for all of his neighbors and they hear him talking so they
know who it is causing the problem. The beauty of this is that there is
no TVI until the offender broadcasts and no transmissions that could be
hunted down or drain the battery power when the offender is not
broadcasting. The neighbors and subsequent FCC complaints will have
more of an effect on shutting down the station than jamming his receiver
would.
What we have created is a simple 'transverter' that receives only local
strong signals on the CB band and rebroadcasts them on the television
frequency, and it only happens when that local transmitter is keyed....
So as far as the neighbors and even the offender are concerned, the
problem simply HAS to be in his equipment!
Not that I would ever really USE any of these terrible things of course!
Thanks for listening,

oooooh. :-Q Vicious.
The little wideband FM tone TX is very similar to the ones deployed
successfully upon local targets around here... Although I personally
would know nothing about their deployment.

Here's one other idea on how to rid the Citizen's Band of a "Channelmaster" or
"Channelmistress" who likes to stir up trouble on the airwaves: once you track
the bastard(s) down, let them know that you're going to publish their name,
home address, and place of employment on the Internet if they don't settle
down. I've found this particular tactic works quite well to squelch CB trolls
who have no life other than to raise H & D on 11 meters every night.

Sounds like a "most excellent" solution!

#12,
I tried to respond by email without luck. I'm up north by the state line
about 50 miles north of Chicago. Like to discuss you ideas.

Is is possible to track someone down.. if they live in the city...
that'll be hard.
A cheap directional finder can be made. Check old CB Radio books.
