Yesterday, I tested Tetsuo Kogawa's Micro FM transmitter on a solderless breadboard, and had all sorts of difficulties with stray signals and wonky performance. Today, I rebuilt it on a chunk of single-sided copper PCB material, and it works much, much better. Check it out! Not at all bad for a $.12 transistor and a few caps and resistors.
