My last attempt at building a simple oscillator did not go so well. After doing research on harmonic electronic oscillators, I finally came across one that seemed relatively simple (not a whole lot of parts) and that had an easily computed resonance frequency, the Clapp oscillator. I have encountered two problems. Fist, all diagrams I've found of Clapp oscillators don't have much more detail than the following I found on Wikipedia: https://en.wikipedia.org/wiki/Clapp_oscillator which says that it has no direct-current biasing network shown. What should this added network look like? My other problem (or rather question) has to do with the transistor used. It appears to be some sort of field-effect transistor. Can another kind of transistor be used, like a 2N2222? Thanks.
