Yes with İonic Chamber. |

I think the "phenomenon" above the target is null, or at least very small, so all the lrl behave in the same way. My lrl does not have an ionic chamber and I honestly do not know how useful it can be. Esteban said that even the Mineoro (with the ionic chamber) was also sensitive to other metals, although to a lesser level.

Yes Franco , absolutely correct ,Receiver with Ionic chamber not sensitive only for Gold, its sensitive little to little of Silver, Copper, Bronze ... and this is problem for me , because I need Sensitivity only for Gold or only for Silver . Best Wish. |

But LRL of Francoitaly is not Ionic Receiver ( after ) yes with İonic Chamber ??????
humhum you are confused ! |

do you remove L 3 turns when you convert your LRL to Ionic mode ??? |

HI ALL
HI ABDOU2014 IF YOU REMOVE L3TURNE AND REPLACE WITH 100NANO FARAD CERAMIC THE FRANCO LRL CONVERT TO IONIC DTCTOR |

in this field indicator, the diode used is high frequency 600-1600Mhz, what is the best diode for FM range , Thank you !

Hi all
abdou2014 l belive the most important effect in franco lrl is self oscilation design your display pcb for reduce self oscilation Best regard zakari |
#2113
|
|||
|
|||
if you build your PCB in double face, side / component with their connection , side / ground, as described Franco, it will have no self oscillation.

I remeber once, while testing my "Franco PLL", that in an area of 30X30 meters aprox, there was a well noticed minimum. It was the only "null" in this 30X30m area, I don't know if was any other null outside. Anyway, in your case, how you can be sure that actually you are above a hidden treasure? |

the correct sequence is this: Proceed in the north / south direction (preferably, to have the greatest detection distance), if there is a target we have a minimum signal, continuing the signal increases but above the target the signal is zero. Best regards. |

Hi Dear Bill512, * My Ionic Device not is from FrancoItaly LRL circuits. * Test with my Ionic LRL for Treasure not is first , I Do very Test with it. * Initial Signal detection of Target (or Sens) was from 600 meter long, and when I was on Target , this Signal is Disappeared, around 5 meter (Radius=2,5 meter). |

Hi Dear Abdou2014 , You can use 1n4148 (nS) for FM circuit, because https://en.wikipedia.org/wiki/1N4148_signal_diode The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and ... the JEDEC nomenclature. The 1N4148 is useful in switching applications up to about 100 MHz with a reverse-recovery time of no more than 4 ns. ( 250 Mhz). |

I know that you have your LRL's like the "Homemade Mineoro LRL". The question is ,did you dig for the "Target" or not? regards |

I got very good signal with MD,law in my country not posible for dig. I have and other signal from my garden before 10 years I buried only Silver of 40-50 cm deep , and my Mineoro also sens this Target. I Have other more Targets.... But without dig , only with MD. Regards. |

Antenna amplifier
I will post here an improvement suggested by a member of the forum.
I tried this change and I found that it really works. In practice, the phenomenon is amplified before reaching the base of TR2. This allows to have two main advantages, the first is to be able to use a shorter antenna, but the main advantage is to make the tuning of the sensor stage less difficult. In fact, it is no longer necessary to obtain the maximum gain with the risk of self-oscillations. Even the pcb is less critical. The missing gain is then supplied by the antenna amplifier. The only calibration of this amplifier is to adjust the 4.7K potentiometer for maximum sensitivity. |

what is the display compatible with this change ?

As for the display nothing changes.
