Making an AM radio receiver with your own provides so much fun and knowledge in the filed of electronics. The circuit shown below is an AM radio receiver with three transistors. The circuit is using three BC548 transistors and few other parts. You can also find other AM receiver circuits

   


in this website using ICs like Simple AM Radio Circuit Using TA7642 IC, AM Radio Receiver with MK484 IC etc but if you cant find these ICs in your local electronics shop than this circuit will work for you. The performance of the circuit is same as the circuits using AM radio ICs. The coil L1 is equal to 80 turns of 30 s.w.g enameled wire wound on 10mm diameter and 45mm long ferrite rod. You can also try other MW radio coils you have in spare..
