Malo mi je bila interesantna tema pa sam zavirio da vidim o cemu se radi.
Uvek sam cenio neki rad tipa 'radi sam'. Malo sam googlovao jer me zanimalo pa sam nasao sledece ali posto nisam kompetentan po tom pitanju neznam koliko ce ti to pomoci ali evo sta sam nasao:
Schematic of single-turn BFO detector:
Battery:
B1=9 volt DC power source.
Capacitors:
C1, C14=22 Micro Farad
C2, C5, C6=0.0015 Micro Farad
C3=10 Micro Farad
C4=0.0036 Micro Farad
C7=47 Micro Farad
C8, C16, C17=0.27 Micro Farad
C9=0.01 Micro Farad
C10=330 Pico Farad
C11=660 Pico Farad
C12, C13, C15=0.1 Micro Farad
Resistors:
All resistors 1/4 watt.
R1, R8, R9, R12, R13=220 Ohms (red, red, brown, gold)
R2, R7, R10=2.2 K Ohms (red, red, red, gold)
R3, R4, R15=1 K Ohms (brown, black, red, gold)
R5= 4.7 K Ohms
R6= 270 Ohms
R11=470 Ohms
R14=100 Kilo Ohms
Headphone Jack:
J1= Headphone jack 1/4 or 1/8 inch
Inductors:
L1, L3= 4.7 mH, choke coil
L2= Broadcast band loopstick (adjustable)
L4= Search coil, a loop made of copper wire(1/4 inch) in 9 inch diameter, 1 inch gap between points A and B.
Transistors:
Q1,Q8= All 2N3638 or equivalent PNP transistors.
Others:
S.C.= Shielded Cable
