i need to complet circuit

Without being able to read the values of the components in the schematic, hard to tell what frequency range it's intended for. I suspect not VLF, but MF or higher. Also, at a glance it looks like an IC manufacturer's canned circuit, except for that horizontally oriented E-field or possibly 1/4 wave (or so) antenna.

The right question to ask is not how to complete the circuit, but to ask why someone posting in an LRL form believes they need it when they admit they don't even know what the heck it is. In other words, this doesn't really have anything to do with technology, it's all about understanding how the human mind becomes deluded.

So I'll ask the question. Reza Vir, what makes you believe you need this circuit, when you don't even know what it is?

PS: if the circuit turns out to be a good VLF receiver, I might be interested in it myself-- but NOT because I believe it's any use for locating buried gold!

I believe that this circuit is a Wolf range and frequency selection
But this circuit is not visible
Do you have a quality main circuit?

I've never lived anywhere that I had any need to detect wolves; however their howls are in the frequency range of human audible hearing and I still have good hearing even at my age.

I also have quality main circuits for many things, but most of them I do not publish on the Internet. Some of them have been published by others on the Geotech website.

So back to my question: what makes you think that a circuit that you don't even know what it is, is important to you? Obviously this is not a matter of technology, it's about human psychology.

PS: If what you want is a VLF receiver, you're posting in the wrong forum, you should be posting in a forum where people who understand VLF receivers discuss such things!

I need a circuit that silver and gold detects PD
Do you have a good circuit?

yes my dear
do you have this schematic?
