I see no reason to try and jam the entire band. Just put together a
simple FM transmitter and as someone earlier suggested, transmit a
squeal or something equally irritating over whatever station they're
listening to. As M->P suggested, that will be far easier to accomplish
technically. If you need schematics for a simple FM transmitter that's
very easy to build, yet very effective I can help you there. I've
built and used several on this design. In fact, there's a drag strip
in GA using a transmitter I built off of this schematic using it to
transmit race stats so people can listen in their cars and with head
sets so they can hear over the loud car exhaust. Also got the board
foil design and component layout making it super simple to build if
you want to go the professional route.

You will only get yourself in more trouble by jamming their radio.
They can come over and beat you up if/when they find out who is jamming.
You can go to jail or pay heavy fines when the authorities discover you,
and they often need only a few seconds to pinpoint the source of an
offending radio transmission.

A much better alternative is to increase the sound isolation between you
and the neighbor.

Use some wooden planks to build a frame which covers the wall(s) to keep
the construction steady. Put sound isolating material in the frame, use
heave cloth type of materials, like heavy old type mattrasses (not foam
plastic), different types of mats, wool blankets, etc.

Fiber board is also good, combined with thick layers of heavy textiles on
both sides.
Put heavy mats on your floor if the sound comes from there.
Build an inner ceiling if the sound comes from up above.

After soundproofing your apartment, or parts of it, you can use your own
sound source to create a low volume but masking effect which means you
hear a lot less from your neighbors because you have your own favorite
music running day and night.


Another alternative is to talk to them and tell them to stop disturbing
you. That will work if they are actually trying to make you do that.
There are lots of religious people who are actively trying to make their
neighbors strong minded so they can come to God or something like that.

A problem with that approach is that they will probably only be
encouraged by that and start other manipulations to force you to become
even stronger. So you will end up with your brain filled up by the holy
wrath, or the holy spirit, just like their brains.

I can't speak for others, but no amount of money would convince me
to sell out my own ethics so easily.

I suggest you involve your local police. There are likely noise
ordinances in your area which your noisy neighbor may be in violation
of.

I thought the person already had a transmitter

Oops... didn't read all the way down, now did I.

The person said the PO was 5 watts. That sounds like a home
brew unit. I used to own a 50 watt exciter. It was
responsible for generating the FM frequency, modulating it,
and amplifying it to 50 watts where it was originally
designed to feed a 5000 watt commercial transmitter. It made
a pretty decent little pirate radio station. I built a
J-pole antenna out of some wire and PVC tubing and I got
about a 5 mile radius with full quieting. Called the station
WEED, muhahwahahahah.

How or where do i obtain the schematic and cb layout ??

Hehehe. The little unit I was describing is good for about a mile
radius with a properly tuned vertical dipole. I've used one in a
convoy so everyone in the group could listen to the same jams on the
trip.

Let me run to my office (where it happens to be), grab it and scan it
then I'll stick it on one of my web servers and post a URL.

What's the power input to the final and what final amp ?

 

[Me]

What's the power input to the final and what final amp ?

9 vdc keeps it legal, but it'll take considerably more.
As far as the final... ugh... IIRC the final was a 2N3096, but I'm not
sure now. It's been quite a few years since I did anything with that
print. Will post when I've got it up.

Hmm that 2N3096 is just a little what, 500 mw max ?

IIRC what I had had a single stud mounted MRF 315. 4 watts
input, 40 something out on a 28 volt Vcc.

Don't recall now. Was thinking the 2N3906 would handle 1.5 W, but my
books are at the office... and that may not have been the final
anyway. I just don't remember. I do recall that heat dissipation, not
max VCEO was the limiting factor on the power output and hence input
voltage. Will post when I have it.

The nice thing about this little gadget is that it can be built on a
board the same size as the 9v battery driving it making for a very
compact unit and it'll still make a mile with a decent antenna.
Actually, I've got plans for much smaller transmitters designed for
use as "bugs" that aren't much larger than the 2032 button cells that
drive them although the range is considerably less. I've never
bothered to assemble one though. This sort of thing would be just an
experimental toy to me as I have no real use for such.

I've seen those things in -kit- form. Some with stereo
output. 9 volts keeps the power under the legal limit but
crank it up to 15 and it doubles. I set up one for a guy who
had a drive-in restaurant. He had a 50's theme and wanted to
broadcast 50's music for the drive in customers. Worked
pretty decent once I found a spot that had no other local
stations.

Ya, exactly the same thing I did for the drag strip. This wasn't a kit
though. I don't recall who did the circuit design or where I got it
from but it was just a schematic and description. I did the board foil
design for it on a computer several years ago and built a few.

Last board I did was a little deal that sensed which of two
assembly lines were down and then paged the right group of
Millwrights to come fix it. It was just something to sense
motion or the lack of it, then drive a two channel paging
radio and some Motorola Page Boy pagers. Oh and I
re-crystaled the pagers to match the channels on the radio.
As far as I know that system is still being used today. I
deployed it over 10 years ago.

Before that I built a DTMF generator box to phreak phones
with. Copied it from a real working Black Box. Ripped off
everything I needed from Radio Shack. Board, etch pen, acid,
741 op amps, everything even the case and touch tone pad.
I ended up destroying it when my Greek buddy got popped by
the FBI. While he had the original black box, he taped his
girlfriend's back in Greece phone number on a reel to reel
tape recorder. Then to call her, he would just hold the
phone up to the speaker. Couldn't use a little portable
recorder, too much wow and flutter to reproduce a steady
enough pair of tones. The FBI never knew about what I had
built, just the tape.

Legal on the FM band is about 30 nanowatts.
