I thought some of the more technically inclined here might find this interesting. i know it is only a simple circuit but this is my very first attempt at home brewing an electronics project from only a schematic. let's see if any of our tech heads here can guess what it is or what it is for. some of the tech specs are the 2 coils are 6 turns of #22 solid copper 1/4 inch diameter and the 2 caps are 4-34pf variable the transistor is an NTE23 / Toshiba 2sc2498. the parts were scrapped out of old electronics that people discarded over the years.
