You need two of this circuits to create a duplex communication.
Duplex circuit adjustment: connect those 2 circuits thru a cable and inject a sinusoidal signal at 1KHz and 5Vef voltage into one circuit, the others circuit input must be shortcircuited. Adjust P1 for a minimum value at K2, then increase signal frequency to 10kHz and adjust C5 for a minimum value on K2. Repeat this operation for the other circuit.
