WebMay 24, 2002 · My contribution was to lift forward the Butler oscillator as an alternative the common Colpitts. A Buttler oscillator is not an alternative for most people since it requires special crystal (series resonance is rather unusual these days). Still, I'm very interested in how a precision oscillator is made (those in a rather large metal can). •••
