With the help of this FM, many different stations can hear the sound without power. Meaning there is no need to provide any extra power inside this radio. But the longer the antenna of this radio, the clearer the sound will be. If the radio station is close, short antana will be done, but mostly long antlers will give good sound.
On this circuit, I have used a primary cuckoo and a secondary cuckoo. The primary cuckoo will be 1 meter long, And the secondary cuckoo will be two and a half meters long. The thickness of both cuckoos will be 32 - 33 AWG. One Capacitor will be 302pF and one diode will be 1N34A Germanium Diode, An aluminum stick and a female 3.5 audio Jack.
