The aim is to decrease the gain of the stage in order to have a stable oscillation but without distortion. The gain depends on several factors, the beta of the transistors, the resistors and the emitter capacitors.
The triggering of oscillations is due to parasitic capacities and is normally an unwanted defect but in our case we try to get it. As it is a bit laborious I thought of an external oscillator and a double-sided pcb with a face connected to ground in order to avoid self-oscillation. Following the help I provided (helps.txt) you get an optimal functioning.

Thank you brother,god bless you.

Hi to all and happy new year.

Mr Franco i want to build this lrl :

https://www.longrangelocators.com/fo...&postcount=213

Tell me please. The price off capasitor in sensor stage C5, C7, C11, C12, C15, C16, C17, C18
is milifarad or microfarad? this is ceramic capasitor?

Thank you in advance. Happy new year

Happy New Year to all forum members. All the capacitors you mentioned are of the ceramic type and the value is expressed in nano Farad (nF). I post here the warnings for tuning.

Hello
i built the pcb for franco lrl using bc547c but doesn't work.
Where is the problem

My lrl (like everyone else) only works with metals that have been buried for at least a few weeks or months. It is necessary to have a test field.

hello mr franco
I m changed bc547c by bc184c
I finally managed to start the LRL
examines it at home by detecting the MHZ signal
waiting for the examination to the field

If at the output of the sensor stage there is a stable signal between about 2 and 5V (DC signal) and touching the antenna the signal decreases even slightly, then the lrl is ready for outdoor tests. It should be borne in mind that there are many sources of false signals inside homes that should not be taken into consideration.

But on the DC output is between 7 and 9.88V and not 2 to 4V. Yes oscillation is

I put that later because now I have problem with ISIS.

Hi
I am a beginner in electronics, does the PCB that you sent in Franco's answer track the gold buried underground? How many meters deep does it show?(Follow this attachment,lrlfrancobase)
I ask you to forgive me for I am new in this regard.

thank you

I don't understand exactly what you want to know, I advise you to read the older posts. However, I am developing an improved version of my lrl and you will be able to better understand how it works. For those who have already made my lrl I say that it is only a matter of modifying some components.

Thank you for your answer, be successful and proud, in fact, I am looking for gold buried underground and I want to know how many meters (depth) your lrl searches for buried gold underground and answers me? What parts of the circuit such as capacitor, resistor, etc. should we change to achieve more depth with high accuracy? thank you

We are waiting for these big news !!!
Thank you.

I don't know how to give you the answers to what you ask me. I have used my lrl very little in actual research. I assume that, as with other types of lrls, the depth can also exceed one meter, but it depends a lot on how long the metal has been buried. These days I am trying some modifications that significantly increase the sensitivity.

Hi FrancoItaly

To build your LRL, do I have to build according to the ''lrlfrancobase.pdf'' file ?
What should I do to strengthen your design?
Is your LRL an ion finder?
Does the LRL become stronger with the placement of the antenna?
Thank you

I post my original lrl, the antenna amplifier and pcb by Dream man, but for me it's better a single pcb for sensor stage. Before connecting antenna amplifier it is necessary to fine-tune the original version. I don't think this is an ion amplifier and the antenna is needed.

Dear Master Franco , now I understand with how method works Your LRL ,
I think that also You know reactions of Hallo effect on Your LRL , because before
You say me that your LRL works with different Mhz , this is only for Oscillator stage , but
setting is Different .....

Yes it is, a further improvement that I am working on is to tune L1 / C10 on a harmonic of the quartz oscillator. To do this, you need to find different frequencies. I attach a new display stage that allows for better tuning.

hello franco https://github.com/dysonlin1/Air-2 The person who predicts the earthquake is actually doing business with your logic. I had the chance to examine this issue. The circuit controls the change of electric current in the air.

Thanks for the information but at this link I don't see anything that looks like my lrl.

[brain]

Not lrl, logic reacts to the same franco lrl metal phenomenon, air2 reacts to the electrical energy of air.


can you examine the link

The "phenomenon" is very complex and still unknown to mainstream science. There are other types of lrls that work with principles and frequencies different from mine, for example Alonzo PD with coil and ferrite or Infrared and ultraviolet. In my case the whip antenna presupposes the existence of an electric or electromagnetic field.

Thanks for the message, I will try to repeat this project, only I need to change the indication from the Arduino board in order to do without a computer on the ground. And it will be possible to try the search for metal buried objects in the ground.

Hello Mr FrancoItaly

How do you do sir?

Any new LRL project from your lab?

Best regards !

I'm fine and you? This is an improvement of my lrl, I will post all the details soon.
