and between XTAL and earth there is a diode.
Can you see it now? 😊

Based on your incorrect assumption there are 11 diodes between ground and the following components in the diagram

D1
C1
X1
C3
C5
C6
Key
R3
D2
D3
Audio pin 2

Do you see how wrong you are now?  ;)

Those are ground symbols.

Look at component D2’s symbol: a triangle with a bar across the pointy end of the triangle. THAT is a diode symbol.

Christ, the post has become tiresome!

Yeh it's not a diode we get that.

I think the idea WAS to insert one for some reason?

Anyway, single device running flat out getting so hot it needs a heatsink.

There are way better designs.

Simple = compromised.

Osc-buff-class E PA, would use far less current.

You’ve made my day! 🤣

Glad you got religion but the OP doesn't need to be misled into putting QRP's useless diode in series with the crystal.  I will credit QRP for having a high loss notch filter to assist in ignoring correct information.

Agree but the OP built it, can have fun running it and find out how short the life of the 2222 is then build something better. I would be more concerned that the crystal frequency will put the thing in the crowded Amateur 40 meter band. It should be padded to pull it below 7 MHz and be easier to hear at a distance.

To me it's not tiresome if the OP succeeds in having fun without QRP's bad information. If it was a _varactor_ diode then I would concede QRP might know something useful.  ;)
