Description
AM transmiter 3 mHz
Coil L1 has 80 turns of 0.32 wire - with a tap from 20 turns. Coils L2; L3 are the same and have 20 turns of 0.6 wire.
All coils are wound on frames with a diameter of 12 mm.
Tr1 is wound on a ferrite ring with a diameter of 10 mm and a height of 5 mm. Twenty turns of folded and slightly twisted 0.25 wire. Winding is carried out evenly throughout the entire ring.
Tr2 is wound on the same ring and contains 18 turns of 0.32 wire folded in three.
Please note that Instead of images of transformers I used images of coils.
