Lrl from Italy

[FrancoItaly]

Hi mustefa,
I do not know if the salt accelerates the phenomenon, however, the salt does not corrode the gold and perhaps not be able to accelerate the phenomenon. I do not know if sensitivity to fluorescent lamp somehow has to do with the phenomenon.

hi to all
this is new version pcb of franco with 4046.I hope the good work

[FrancoItaly]

Hi mustefa,
great work, you give a professional look to my LRL. I hope you have the same result on the field!
Regards

thank you very much franco.
I'm also hoping
franco ?Can I use the bc237 instead of bc183?and bc548 instead of 170?
If constructed properly by touching the antenna output happening?

Yes you can dear Mustafa . Nice work and job

[FrancoItaly]

Hi mustefa,
I think that all transistors type BC238, BC108, BC548, BC109, BC239, BC549 and similar are OK but only type "C" (BC109C, BC548C...) because they have much more gain.

Hi mustefa,
If you touch the antenna the DC output signal goes low.

With what program did you draw?

I have designed with professional software altium.This is software for industrial design

[mustefa ubram]

thank you very much dear franco
I will soon make Type 4046 with new version pcb .And tell you the result.

Very nice work mustefa. Do you have a pcb design for crystal osc type?

I sent complet pcb in last page for crystal osilator type.(sperint layout file)

hi mustafa ubram
I build version 3 (8 mghz sensor )
my result like you mustafa
I sense tv and mobile phone signal
and can't detect my buried silver

[mustefa ubram]

Hi franco
I found th transistor bc237c.is this transistor good for replace with bc180?
Whether work your lrls only with C suffix?
I did not use a transistor circuits before with the suffix C?

[FrancoItaly]

Hi mustefa,
Perhaps the LRL also works with BC ... "B" with less amplification, but I have not tried it. I think it is better not to make changes and use the "C".
If you do not find the "C" try "B" but it will be necessary to reduce the value of the emitter resistors of 1K and try 820 or 680 or 560 ohms.

hi franco
i am sorryi make your lrl 4046 again with new pcb.but I could not get a result.When I'm touching the antenna does not create any change in output.Voltage does not decrease.But when the the mobile is close to the antenna LED is illuminated.Even when I disconnect the LC circuit. Again shows the response to the the mobile.
What do you think?
please help me

The "phenomenon" changes the phase and the amplitude of the signal

dear franco
Please complete this more and more clearly explain how to operate the system?
When the signal is produced by the LC circuit?
What makes the phenomenon of changes in signal?
What is the function of capacitor C10?
Whether the VCO signal enters directly into the amplifier?
What is the function of the LC circuit?
Why use two capacitors C8-C9?
If you are is possible to explain fully.
TANK YOU FRANCO

Hi Mustefa,
I want to start by saying that I do not know much about the true nature of the phenomenon and that what I say is good for my country and I have made known my LRL also because I want to know if it works in other countries.
The LRL is based primarily on a high gain amplifier stage. The signal to be amplified comes from the VCO of IC1 and is applied to the amplifier through C8 and C9. The required value is about 0.5 pF, the value is difficult to find, so I used two capacitors of 1 pF connected in series. C10 has a double function, it carries the signal coming from the antenna to the base of TR2 and it carries part of VCO signal to the ground via L1. LC filter certainly let a signal that has the same resonance frequency or a harmonic or a sub-harmonic. My LRL works only with 2 or 3 turns for L1 and 22 pF, but it's possible that other turns work fine in other country.

Best Regards

Please explain this more if it is possible for you.?

[FrancoItaly]

Hi mustefa,
Unfortunately I can not say more, but the important thing for me is that the LRL works well.
Best Regards

[king40]

we need to try and more experience to found information about phenomenon

[mustefa ubram]

hi
i made 4046 complet. I've tested with various rounds coil of 2 -10 rounds.
But it does not work:fro wn:When i touch the antenna voltage will decrease
But the real purposenot operating.I do not know nothing

[Nicolas]

Hi friends
I put here this scheme for use with all LRL to see the decrease of DC en ?millivolts
this scheme is for 0 to 5V. if you need other band need change the value of R1 and R2




And I have others Model I put here when I have times

[FrancoItaly]

Hi mustefa,
Sorry but I cannot help, if you touch the antenna and output decreases the lrl is ok, perhaps your test field is not good.
Regards

dear franco
In field experiments need minerals underground phenomenon to be

And also the need for depth
