RX circuits of the Minelab Explorer II

Andy_F , Nice Work So-Far on the schematic !!!!!!! Are you sure about the TL072 "Dual-JFET low noise opamps" because you have a question mark on the schematic???? The numbers must be scratched off of your detector !!! Minelab as usual ......Anyway , if you get some free time also post "just the TX Oscillator circuit" of the Explorer II . Thank-You and welcome to this Great Forum !!............Eugene

Hi, Eugene.

... because you have a question mark on the schematic????

Question marks stand there, where not absolutely authentically.

The numbers must be scratched off of your detector !!! Minelab as usual ..

Yes, but there is an indirect information.

....Anyway , if you get some free time also post "just the TX Oscillator circuit" of the Explorer II .

TX circuit is known for a long time, is the bridge on 4 MOSFET. It is not interesting.
Operating signals of switches of RX circuit are more interesting.

RXcircuit

can you show signal on oscilloscope from many RX test point of each 4 channel ? tank

What for oscillograms are necessary to the expert? The expert should know all .
