From the left:
1. Common base
2. Common collector
3. Common emitter
Theres a significant difference in how fast these three specifik designs grow in amplitude. They will however, all three start by them self eventually, and increase the amplitude until they reach a certain level. If you don't want to wait for it, induce noise by shaking the phone.
I tried to make the three amplitudes range in the same area.
The input- and output impedance, to- and from the resonance circuits, effects the frequency due to the nonlinear limitting component in the circuits. Therefore the better separation between the resonance circuit (higher impedance) and the nonlinear component (the transistor) the more precise the frequency, but the lower the loop gain, and therefore the startup time.
