This is a good way

I think your oscillator should be shielded by a tin box separately
|

|

Of course, but we must not forget that even the power must be decoupled.

The biggest problem is that the specific frequency responds to the metal, or a certain frequency, or any frequency,

In my opinion there is no specific frequency for metals, the phenomenon exists in a wide range from Khz to infrared. All that remains is to experiment and it is very important to have a field where to do the tests, it is necessary to bury the metals, for example gold / silver and wait at least a few months or less, it depends on the type of soil.

If it has nothing to do with frequency, there is no need to adjust L1 and C10, their resonance frequency is much higher than 8MHZ

I have successfully increased the distance to about 50 meters

Has anyone experimented with using an aluminum box to install the entire circuit? Will it have any effect?

I placed an fm transmitter on the opposite side of the copperware buried for five years, which emits a certain pulse signal. When the transmitter, the metal and the detector are in a straight line, the signal is particularly strong, and the distance has exceeded at least 300m.

When it is not straight line with metal, do you catch the fm transmitter?

Hello mr Franco.
I hope you are well. I have some questions. First i create sensor stage quartz 8Mhz and is ok (out 5.85V and when I touch the antenna the voltage drops 5.7v dc). When I connect the antenna amplifier stage (without the display stage) what value should I have at the exit? I set it with the potetiometer to 5.7v but when I touch the antenna the voltage does not drop. it's correct? (without display stage). Thank you in advance. |

Hello Franco. The phenomenon is an invisible light beam of negative electrons similar to a cathode ray. It is the resonance of the material. What you lack is a transmitter circuit to raise the kinetic energy of the photoelectrons, so that they can be easily captured. Your device captures them as stray signals from close distances.

Hello. I had good discoveries. Thank you, Mr. Franco, Italy. Although the radius of my discoveries was not more than 4 meters, but I love the circuit of this device. Thank you.

Not because it is said to interfere with signal reception.

I am happy that you have had good results with my lrl and I thank you for having said it publicly for the benefit of those who do not believe in the phenomenon or at least are in doubt. Other forum members confirmed it privately but asked me not to disclose it.
