I build one of this a few days ago and it was suprisingly good working. More than 100m. This one will oscillate from 48 to 96MHz and its amplitude is a bit low. And there is no impedance matching for an antenna.

because it will depend on the transistor you will use

I used a simple bc337, and the simulation was not far away from the real behavior
