Full resonance. By a small shift around the resonance of the receiver, the phase of the received signal is also determined. It must be obtained so that it corresponds to the medium of adjustment of the signal of the balance of the ground. This is easily done with a sample with a piece of ferrite. It really takes time. Then the resistors determining the discrimination are selected. It is possible to put a potentiometer to adjust the discrimination. The coils are with electrostatic screen, OO or DD type.

Yes, there is a connection. It's hard to see.Comment

It is good to connect 100 nanofarad capacitors to the receiver input after the 6.8 kilohm resistors. It works better. This is done in the improved version.Comment

I'm an adult now. I see poorly. But my brain still works. Don't be angry with me that everything is poorly drawn.Comment
