Hi everybody I'm new one
Firstly you must know that i don't know enough english
I'm trying build a simple oscillator and every time i'm fail.I'm very stubborn about this situation.
For example below oscillator circuit is very popular in simple rf tranmitters but i couldn't work it i don't know why
C1=1 uF
L1=3 mH
Transistor is NPN
R1=100 KΩ
C2= doesn't matter?only for feedback, isn't it?
Acording to my calculation oscillation must be about 3 KHz and if i add a headphone between emiter and negative side of power source i must hear the sound but no sound.Where is the wrong?
