Electronics Projects: Simple FM Walkie Talkie
Hero Banned Dec 3, How to Wind the speaker coil You may use a small audio transformer for the shown speaker transformer, or alternatively diahram it by winding around 70 cirvuit for the primary left sideand turns at the secondary speaker side. The circuit includes an auto tlakie as well as reset switch and produces very accurate and stable readings.
