Butler Oscillator.


Popular and effective overtone oscillator !
The Butler oscillator.
Tested on a breadboard .
Frequency stability is acceptable with this unshielded circuit.
The warm up drift in range of 100 - 200 Hz.then after it was stable with
slight drift of 2 to 3 Hz.
No neutralized inductance use in parallel with the crystal.
