Lrl from Italy

[sweker]

I briefly summarize the operation, the sensor stage amplifies the oscillator signal which must be very small otherwise the sensor stage is saturated, in the mixer TR2 the mixing of the oscillator signal and the "phenomenon" takes place. Removing the crystal, therefore without oscillation, the output must be 0, if there is a DC signal it means that the whole sensor stage auto oscillates, an undesirable condition because putting the crystal would have a low sensitivity. Then decrease the amplification until the output is zero, this can be done by decreasing C13/C/14.

MR Franco can I add antenna amplifier on the same pcb sensor stage ?

Yes.

Although in several years this thread has surpassed 1,000,000 views, a huge number considering this is a very specialized topic. I want to thank everyone who actively participated in this thread and also privately. I think my lrl was the only one for which all the data and assistance to build it were given, I was told that in some countries the kit is sold and I don't mind it, on the contrary it is further proof of the goodness of the project, furthermore not everyone is able to make the PCBs and the calibrations.

I also thank God very much, and then thank you because you were so generous and did not skimp on us with any information and did not spare any effort to help us , thank you Mr franco

[FrancoItaly]

Thank you for your compliments.

Yes.

Adjust according to Franco's recommendation. Be sure to top layer copper to avoid vibrations.

thank you so much bro , but it does not open with spring layout 6

You are the first who complained. I downloaded it myself and everything opens. Do you have the sixth version of the program?

Demo version, this is a limited version, which is probably why it does not open the file. Install the normal version.

this device does not work.I tested all versions..but here in Brazil, it's useless!!!

in which way do you mean by it does not work,it does not work at all or it does not catch the phenomena?

it works in other countries.. here in Brazil it doesn't get results! but I heard opinions that in several countries it proved to be efficient

Many thanks to the hardworking managers and Franco. Is the effect of the earth's field on metals in the plains and mountains the same, and does this system react in the same way for these areas?

Unfortunately I cannot give an answer, having little experience on different types of terrain, but since the phenomenon certainly also depends on the earth's magnetic field, I believe that there is little difference between mountains and plains. Instead, near the equator, where the north and south poles are at the same distance there could be an attenuation or perhaps disappearance of the phenomenon.
