@@AllElectronicsChannel Might have a lot to do, with the active device used. The ft of the transistor was not very high and it wasn't a good choice for a high frequency circuit. The Crystal was not tested before entering this circuit to see, if it would operate at other frequencies rather than just the fundamental which was 16 mhz.
Thanks!! The tap is more or less 1/3 from the cold end. The capacitor is calculated to the inductor at the output frequency. I think I used something like 6-20pf. In the description of the video I placed the link to my article, take a look! 😝

The crystal I have used obviously isn't an overtone type as I can only get it to oscillate at its specified frequency of 16mhz, nothing else.
It is hard.. I think it should resonate. Maybe it did not because its losses are too high.

WHY DID I NOT FIND THIS CHANNEL BEFORE!?! Fantastic! 👍😁
Thank you man!!! Let's grow it together!! 😁😁
The crystal oscillator Q is very high 👽
Thank you very much i did this circuit i works great. Please can you make a video on an RF amplifier for this circuit
I have video about amplifiers that may help. Take a look on the channel!
A pleasure to watch your videos, as always
What active device did you use in this project ?
That probably is a simple BF199. Any more modern BJT will do.. Even the common BC847
excellent video as always. very useful. what was the tap point on the top inductor and the value of the variable cap?
Thanks!! The tap is more or less 1/3 from the cold end. The capacitor is calculated to the inductor at the output frequency. I think I used something like 6-20pf.

Show us please, how you have calculated the values of the inductors in this circuit.
Thanks for the video, very interesting. I think I may need to watch it a few times to absorb the information.
Wow😯which💯 vídeo 👍✨🌟
Is it possible design a overtone XO without inductor?
I think no..
How much amplitude dose the crystal oscillator oscillate voltage ac pp?
I Don't remember exactly, you can see by the power on the spectrum in the video. I think something like 200mVpp
A thumbs up for you. I would have loved to see the actual oscillator waveform. I don't know why it's often not shown. Is it because of nonlinearity?
Thanks!! The timedomain waveform is not so useful for small signal RF.. what matter more is the viewpoint of output power and harmonics
@@AllElectronicsChannel Thanks
Great video
