Hey Folks! Hope you are safe by now..
I was interested in crystal oscillators so I decided to build one myself. Soooo I built this Colpitts Crystal Oscillator on a breadboard using a Tuning Fork crystal oscillator (that's all I have for now) but when I measure the output voltage I get a constant value. Can anybody explain me why I'm not getting a sinusoidal waveform? I attached a picture of circuit just in case..

Thank you for you time!

Matt

 

Look at the comments here about tuning fork type xtals and considerations (bias network, xtal drive level)-
