Lrl from Italy

Hi mustefa,
for me the better is 3 turns and 22pF, the output 2V - 6V.

ok franco.
for detect 2v is best or 6v?

hi franco
I've tested the old buried metal.I've buried two copper bowls 6 months ago.i tested .
But it was futilewhy?

[FrancoItaly]

hi mustefa,
test different directions and different angles of the antenna, it's also possible that the copper do not emit. For my test I have used silver and gold.

Hi Nicolas
At the time I did only test on the test but Rubin with my Lrl revealed a buried copper plate from 25 years to a depth of 60 cm to 4 m in South/North direction and 2.5 m in East/West direction.
Best Regards

hi franco
In this post you said you could reveal a copper plate.So can detect copper?
Or you could say that detect non-magnetic metals such as aluminum.
Which tayp your lrls(8mhz quartz-with 4046 or..) is the best and most sensitive?
Explain a little about the project phase comparator with 4046?

[FrancoItaly]

Hi mustefa,
I think the lrls can reveal all the non-ferrous metal but copper probably needs more time to emit the phenomenon. Quartz lrl is more simple to build, 4046 Lrl needs more amplification, but are substantially equal in performance. The phenomenon changes the phase and the amplitude of the amplified signal and the phase comparator of the CD4046 indicates the variations of phase with the VCO of the CD4046.

Hi Mustefa

Do you have black & white pcb layout in pdf format? Can you please post it here?

Thanks In Advance

hi franco .i have question dear frenid
I've buried 3 gold pieces with salt today.How long should I wait for testing?
i made today your lrl type 4046.I think this is much more sensitive than other types.With the antenna touching or close to the antenna output 358 pin1 voltage increases.this is correct?
What is the most appropriate voltage at the base of the middle p2 ?

Dear Mustafa!
I can't open the file,can you tell me wich program to use or send me PDF file.

Hi mustefa,
in my test field gold targets with no salt emit about 1 month later.
I do not remember if touching antenna output voltage Increases the important thing is that the phenomenon causes an increase in the output voltage of IC2A.
The most appropriate voltage at the base of the middle p2 is what allows you to have the correct voltage at point X.

thank you franco
Is the use salt with pieces gold effects on early emit?
my lrl with 4046 is Very sensitive to fluorescent lampsit detect a lamp of 1meter with steel antenna.By turning the capacitor LC circuit Change in output voltage .And sensitivity to fluorescent lamp changes.Can this be a sign that the circuit works correctly.?
