I was wondering if anybody had a circuit design for a 10.7 MHz
transmitter with a 1 khz tone?
I know someone will say you don;t want this...as 10.7Mhz is a IF freq.
but that is exactly what I am looking for. I have a neighbour who
persist playing music at 3am at high volume..so a short burst burst of
this should make playing the music so loud less appealing.

That would work only if the music is coming from FM radio, of course.
And you might need a VERY strong signal, which is difficult because an
efficient antenna for 10 MHz is of the order of 15 metres long.

Indeed, and a far better/simpler solution is just to use a bench variable
frequency RF generator with a short piece of wire in the BNC output socket.
Works a treat. I used this method when we had some builders next door who
kept playing their radio on a really crap channel very load. Simply tuned
into the with the RF generator with the 1KHz tome turned on. Range over 20
yards blotted out their radio completely. We had a good giggle watching
them try to retune it. Eventually they changed station and so did I. After
a few goes round this loop they decided the radio was broken and switched
it off. Sweet victory.

Good Luck.

I had someone trying to bug me with loud heavy metal, so I set the
generator to the same frequency and retransmitted a C&W station. The
moron got so upset he smashed his radio. Problem was solved, till he
saved enough for a new radio. ;-)

About 1979, my Dad and I had a problem talking to each other on CB radio
over a distance of about a mile or so. There was a person with a high power
base about 5 miles away who intentionally interfered with us. We would
change channels and he would follow.

I got a CB crystal from Radio Shack and built an oscillator modulated by a
555 timer. Lots of good splatter. It was low power and had only a few inches
of antenna. When it was transmitting, I couldn't hear anything on CB except
for a 400 Hz whine.

I dropped it off in a field a couple of hundred feet from the perpetrator's
house. It transmitted for a week or more.

We never heard from him again.

I did something similar back in college. I was in a room living off
campus,
and the dude in the next room liked to play his TV loud at all hours.
I used an RF gen as you pointed out above. After a while the fellow
decided his TV was broken and gave it to me. End of problem... :>)))

You don't want this, because it will be illegal.

You can't tell the transmitter what receivers to affect, and even
if it was legitimate to bother the specific neighbor (not likely) it
sure isn't legitimate to bother the whole neighborhood.

And of course, you assume the music is via an FM radio, when it
could be all numbers of things, like MP3 players and CD players.

Since when has illegality been an off-limits topic in this ng?

and if the stereo is anything good, your little misery generator
will do nothing to it.

Did you ever see one of GE's early TV remote controls? It was AM
modulated with one of four tones, right above the AM broadcast band. I
graduated from High School in 1970, when those crappy pocket sized six
transistor radios were popular. I found one of the GE remotes in a pile
of junk donated to our ham radio club, with a TV that wasn't worth
fixing. I added a padder capacitor and retuned it to the only rock
station in the area. Every day for a week, I randomly punched the four
buttons, till no one even bothered to turn a radio on.

The remote = free.
The padder capacitor = free.
The silence = priceless.;-)

Well thanks to all for the input....Yes not legal...but nor is paying
the cops off so they don;t shutdown the extremely loud party at 3 am

If you are anything but a liar, you would take your evidence down to your
local DA and file a complaint!!!!!!
