The TDA is for CAP reception, we can use two rx coils TDA and DCH , or use TDA as stimulator for DCH, The question for master members is : the TDA cap reception alone without DCH coil can capture the phenomenon ???
the adventage for TDA rx alone is the immunization to the interf?rences .

I already sent you a message in your private box, but you did not reply.Originally posted by abdou2014 View PostI tried many configurations, like positioning the vhf oscillator in a way that it reacts only to non-ferrous metals a few centimeters from the antenna .... but I want to know which of these configurations you worked with ???

DCH 85 has special settings that I think not everyone can do.
The receiver circuit must be adapted to the transmitter part. You must have done it. Because your circuit was sensed from a distance of 60 meters.
