Hello everyone.
I assemble with slight changes project Miner-4 from pulsdetektor.de
The case is in the form demo, for testing.
Here is a photo of the first battery calibration.

I have a problem with making the appropriate coil.
Interested in electrical parameters and dimensions, shape of the flat coil.
I've heard different things, optimal inductance at 300-350 uH, resistance of 2-3 Ohm, diameter 28cm, wire 0.5-0.75mm2.
But this coil is impossible to perform, not for that resistance or cable size.
I also saw a pdf file with the coil from pulsdetektor.de to Orion similar to miner-4 detector.
I checked what is possible have coil inductance, it is much higher than 350uH, I think that there is almost 1mH.
it's not too much?
So if anyone knows anything about the coil to Miner-4 please help.

Best Regards
Artur from Poland

I find this.
L= 1193 µH
R= 2,3 Ohm
diameter(outer coil)= 28 cm / 40 turns
diameter(inner coil)= 11 cm / 30 turns
sectional area(PVC-Insulated Cu.-flexible wire)= 0,38 mm˛
You can also use 0,5mm˛.
