What creates output power? Voltage swing times current swing.
The 2N3866 will have almost the same output power as my 2N3904 transistor unless the supply voltage to it is increased. Then the output current will also be increased and the output power will be much higher.
The higher power FM transmitter will be very illegal in almost every country in the world:
1) It might cause radio and TV interference.
2) It might disrupt airplane to air traffic controllers communications and cause a crash.
3) It might interfere with police, ambulance and fire department communications.
