  • So I made one of these following the same schematic shown on the white board. It has the signal out in a weird spot. I was not able to see a signal there, just the input dc voltage, which makes sense as there is a direct path through the inductor to that "output" and the inductor acts as a dc short circuit. However, when I probed the emitter of the transistor I saw the expected signal.

    This diagram is consistent with other ones I've seen and even the one on the wikipedia page for Colpitts Oscillators. How could you not get a DC short circuit with that setup? I must be missing something.

No public wish lists :(
