I guess it is 1M3 made from 2 other resistors..

Hello Friends,
No…no…. not a secret modification, only lazy me…
I made a error in the colors from the 4k7 resistor. The one on the pcb is 47k !! look at the colors. Have not removed the wrong 47k but fixt a 1k on top of it. The near 22N cap is also wrong must be 10N (thanks Nakky).
Best regards.
Ap
one resistor 4k7 one resistor 47k look close......Attached Files

Please give me information produced coils for 36 or 45 cm smw
Total Rounds score and wire ....
With respect

ApBerg add those 2 caps to hear the differences in audio!
10nf beetwen C and E. 1uF beetwen B and "-".
You will be amazed! Simillar to "bell" at Garrett GTI2500!
Regards!

Answer is: maintain the same value of TX and RX inductance no matter of coil diameter. You can do some corrections according TX and RX resistance too.
So, buy L-meter and training how to use it.

HELLO IVCONIC AND FREINDS
I built the circuit SMW but found some disagreement in the revised schematic and PCB
1. Resistance is 1K, but the PCB schematic with 4.7K specified. Which is it correct??
2.MAX in this circuit does it do?
3. If I can instead of 33 micro farad capacitor Tantalum electrolyte to use?
4. LM7805 specified in the schematic, but PCB 7809. Which is it correct? 7805 or 7809? ZENER 4.7V and not the PCB Why??
5. Resistance is specified in the schematic but 3.9K is PCB 1.8K.
6. BC327 transistor in the schematic, but is in the PCB BC547. Which is it correct? BC547 or C327????
7. Lord, I instead of the BD180 transistor transistor BD140 to use??
8. The schematic 2.7K specified value for this resistance is 27K but the PCB amount specified. Which is it correct?? 27K or 2.7K????
9. I can instead of the IC LF347 IC TL074 USE(REPLACE) ?????
Please help me
With respect

Dear Ivconic WM6
please for god sake dont judge without prove.
i dont know whats wrong with me? have i send a virus? have i said bad words? i didnt make a cime only i asked for help nothing more
also nothing wrong with it your better than me on electronic fields//
so please friend i treat you all of you like real friends not online friends.
u must be the same????
best regrads
