I built an oscilator myself.Well, it's working on medium waves. But it can transmit up to one mile.I found the project in an old book.

I dont know the name.The book is REALLY old.It is actually a whole transmitter.
Here is the schematic:Schematic
I'm from Bulgaria, Thats why I built it.In Bulgaria There is a limit of transmitting up to three miles without having a license.I have the oscilator from here but I can transmit only up to half a mile.

Hmmmm, that makes two of us I guess. What's the name of the book you got this from (it does seem quite old as it uses vacuum tubes)

Yes, I know.And it's a schematic without having any values.You can change them according the kilohertzs you want your transmitter to transmit.
Sorry for the bad description.

Are you sure you mean half a mile, because, that's like 800 m, about 300 m more than 0.5 km. Do you amplify your transmitter? If yes, how much?

The AM Transmitter posted here? I can't hear it outside my apartment. Also, what distance in meters do you transmit.

That's the law.
If it stays inside your house and doesn't bother anyone else,
then it's legal. If your neighbor can hear it, you need a license.
