L43 ... 195 turns (an inductance can be adjusted by the screw ferrite core in the range of 306 ÁH till 680 ÁH)

L21 ... 2 turns

Both the windings L43 and L21 have been wound by the copper litz wire (3 thin insulated wires parallely) to improve a Q-factor.

This coil is great for tuning to 455 kHz with about a 220 pF capacitor in parallel with the main winding.

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