Lrl from Italy

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

[folharin]

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.

exactly sir franco italia !!

I have successfully increased the distance to about 50 meters

[liudengyuand]

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

[liudengyuand]

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.

[tasmen]

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

[liudengyuand]

no

[brain]

no

Can you publish the fm transmitter scheme you made.

[liudengyuand]

ok

Which version of Franco LRL build You and test in upper Video.

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.

Yes, that is correct, however it is better to try the operation without the antenna amplifier on the test field, also to establish the actual improvement.
