#103 coil windings:

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

L21 ... 30 turns

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

The winding L21 has 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

#207A: 1.7 μH - 3.7 μH
