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. |

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 Tasmen |

Help me
Hello
i built the pcb for franco lrl using bc547c but doesn't work. Where is the problem |
#2482
|
|||
|
|||
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. |

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 |

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 ..... |

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. |
#2496

Not lrl, logic reacts to the same franco lrl metal phenomenon, air2 reacts to the electrical energy of air.
can you examine the link http://www.faenzashiatsu.it/Tecnolog...ino_Vonair.htm |

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.
