md schema

A friend buy a MD and I "sacrifice" and "dissect" it. The schematic like this kit type "MD toy". Sorry can't post all the manual (pdf 411 K), because the attachment of the forum is very limited in bytes.

The coil of the kit is concentric (I thing the schematic posted too). The TX coil had 15 cm diameter + 48 / - 15 turns wire 0.15 mm with compensation short loop 5 cm long and the receiver 7 cm diameter 48 turns wire 0.15 mm.
