Components List:
R1, R2 = 10K Ohm (1/4 W)
R3 = 47 Ohm (1/4 W)
C1, C2 = 1nF
C3 = 4,7uF/16V
C4, C7, C8 = 0~45pF trimmer
C5, C6 = 10pF
C9 = 100nF
T1, T2 = 2N2219
ANT = Simple dipole l/2.
MIC IN = Microphone dynamic or other type music source like mp3 player/ PC/Smart phone
Inductor (L) specifications:
L1 = 4 turns, 7mm diameter *
L3 = 3 turns, 7mm diameter *
L4 = 5 turns, 7mm diameter *
L2 = RFC (resistance 1 M Ohm with wrapped around her inductor of enough coils from fine isolated wire. Scratch of utmost inductor and you stick in utmost the resistance making thus a parallel L-r circuit.)
Use 4 more 2N 2219 Transistors in parallel connection with T2
