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!

Yes , before this was public from Abdou in PDK-3 head .

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.

Yes it is this, i know very well.
The half schematic that you attached had been posted from me to an answer to Esteban.
It is the basic receiver of the DCH85...

I do not have Iconos, the POT in the picture and the additional COIL caught me attention, only those who have Iconas can tell for what is this . :)

from what i understand of the dch scheme it is a fm receiver and a circuit with a coil stimulated by the ci 555 and nothing much..
