I own a diy oscillator mounted by me. I use it for testing any kind of crystal. It's based on BD137 transistor. The problem, is that only covers a distance of 1,5 meters away, What I need is just any schematics just one transistor oscillator with the modulator included, with a coverage bigger than 4 meters, and no more than 10. I need it for sending Mp3 music to any near AM tube radio, or add a modulator source to the one I already have. The simplest the better.
Thanks a lot.
