Blue is probably 2 mega and black is 3 mega, only the input amplifier is on one transistor, in a wooden square a sample of the desired metal goes through the kennel to the antenna made on the board. Interesting solution Thanks Zachary !!!!!Although I was mistaken, I saw there are still transistors, the circuit is similar to the one in the DCH-85 that Morgan gave us!

I ask you to excuse me if I made a misunderstanding! Esteban's scheme of course ...... but Morgan gave it on the forum. There are a few differences in this scheme, replacing three parts with one stabilizer.

But will need change with value of R23 and R24 , correct value You will find with try .

The square wood inside the head "says" that this is an Iconos prototype and not a DCH....
Schematics are about the same but there are some small differences.
