#101 coil windings:

L43 ... 70 turns (an inductance can be adjusted by the screw ferrite core in the range of 45 μH till 100 μH)

L51 ... 4 turns

L25 ... 4 turns

The windings L43 has been wound by the copper litz wire (6 thin insulated wires parallely) to improve a Q-factor:

Both the windings L51 and L25 have been wound by the copper wire with a diameter of 0.1 mm

How to determine number of the winding turns if you know the wanted inductance:

You can buy those coils with different inductances from me:

#101:    45 μH - 100 μH

#103:    45 μH - 100 μH

#116:  306 μH - 680 μH

#207:    1.7 μH - 3.7 μH
