Dear Franco I buried one gram of 19 carat gold in a depth of 50 cm
I am sorry for my late

This place was discovered in my house over a span of twenty meters and it turned out to be in the middle of the wall under it

I take this opportunity to ask you if you have verified that the
sensitivity is greater from north to south and that there is no signal above the target?

Dear Franco, there is a signal above the target and the target can be detected from all directions

do not damage the house now because lrl caught something:χαχαχα:

Dear Franco, today I went to the square and discovered many areas, one of them a hundred meters to the north and the other twenty meters to the north.
When I started noticing, I came from north towards south. As for the east and west, the device does not work
The burial point is determined by perseverance

Usually the final step is done with metal detectors, the problem is when the target is deep, beyond the range of the MD.

Yes dear Franco, I will now make this device an Ionic house, because I tried the Ionic house at BDK and it gave me a burial point
Do not be surprised because no one is looking for devices in the Arab countries, and everything is forbidden for these treasures are scattered everywhere

I think any NPN BC...A :

With low noise : BC239 or BC209

Thank you brother,please tell me your first lrl "c6" variable capacitor equialent options?

I don't remember which lrl you are referring to, post the diagram.

I post here all the information to build a working (for me) Lrl, the photo is not related to the last Lrl because now I'm not in Italy ( the 3 stylus antenna are not necessary).

Best Regards

This lrl

Post the wiring diagram, I cannot understand which one you are referring to, however the alternative to the variable capacitor is a varactor.

Varactor value?

Your first lrl "5mhz schematic."

the scheme is in my first post where there is the photo, I post it here again with the value of the components. However, I do not recommend not making it, it is too critical to work in self-oscillation, for this reason I made the version with the quartz oscillator. I post also here too.

Thank you,l"am build this 5mhz lrl,output voltege is 7.7v,this lrl is ok?

No, it is better in the 4-6 volt range, otherwise if the amplitude is too high it would be almost insensitive, in fact if the amplitude is already normally at maximum it could not reveal a further increase.

What should i do next?

The purpose of C6 is to adjust the gain, you can try acting on C6, if it is not enough increase R5 put 1.2 K or 1.5 K.
