The VR3 is the phase potentiometer. This potentiometer can be replaced by a 1K resistor, or must be set to a value of 1K. It works best as the detector.

Thank you. Now I understand it

Blue Max 4x6 Shooter DD (6.59 kHz)

TX = 0,52 mH = 1,7 OHMS
RX = 13,68 mH = 49,5 OHMS.

I've noticed that the inductance and resistance of the coil RX DD does not match that of a concentric coil. In contrast, the TX is very similar. Why?

I think Mr. CARL-NC can give us an answer.
