5 parça malzemeden oluşan en basit ve ucuz radyo devresi oldukca ilk devre şık ahşap ve pleksiglas ile kasa yapılmış bence çıkışının amplifikatör ile kuvvetlendirilmesi gerekli
iki farklı fm radyo devresi var
FM Crystal Radios ?
I have heard, even from a physicist, that it is impossible to build FM crystal radios. On the other hand some experimenters claim that they have built them.
L – 4 turns #18 copper or silver wire, 12mm inside diameter, tapped at 2.5 turns
Ant – 7 inches of #18 bare copper wire
C1 – 18 pf ceramic capacitor
C2 – 50 pf air variable capacitor
D – 1N34 diode or rock crystal
R – 150K resistor
