Good PCB !!!!

[MartyJ1963]

Looking forward to the results Emersonpaz. Regards, Marty

[Emersonpaz]

does anyone know if there are any Aliexpress DD coils that can be used in SMW?

hello master Emersonpaz;
smw detector what stage are you at?
What should be the coil resistance, inductance and frequency values?

Best regards
Gurdal

Hello friend, I will follow according to Ivconic's specifications

The TX coil inductance can range from 1mH to 2.2mH and resistance from 2.5 to 3.5 ohms.
In the case of 1mH; the parallel capacitor is 474 + 473 in parallel.
In the case of 2.2mH; the parallel capacitor is 224.

RX = 160 windings, 0.27 mm wire
TX = 70-75 windings, 0.45 mm wire
In this case, the TX parallel capacitor is 220nF.

I'm missing some capacitors and the 100r trimpot I have to buy

What template are you using for the coil?

Hi all
Is there a coil inductance, resistance and frequency calculator all in one?

Hello Emersonpaz.
Do you know if this resistance is important, it does not appear in the diagram?
you can see it in the link in # 156
