Simple AM FM SW MW booster Circuit

Today Free Circuit Diagrams 4U is going to give you a very useful schema diagram in some countries we can see some radio signals are poor so this is the best answer .Here We have used very common Transistor MPF102 use470uH Coil for short wave and use20uH for L1.You can run this schema with 9V






Note: 
          # Dont supply over 9V 
         # Build this schema on a PCB 
         # You can use  NTE 451 or 2N4406 instead of MPF 102
