Lrl from Italy

[FrancoItaly]

Hi HOBBIT
Tune P1 for about 3Mhz, tune P2 for about 1-6V (AC signal) at point X and at pin2 (phase comparator output) a DC signal 0.5-6V. This is not a metal detector and hand tests serve little. As I said and I repeat here there is no other way to test the lrls, you must have a long buried metal that is in same place at least a few months (for my experience) or to know a place where there is surely a long buried metal. An empirical system is exploiting the compass effect, you need to adjust the gain towards the maximum sensitivity until you have the compass effect then you have to lower the gain until it disappears. This happens with my lrl.
Best Regards

hi to all

construct lrl Franco and I but do not know how to adjust to being very sensitive, putting his hand on the horn grabbed by 2-3 cm, is correct that this distance must be more sensitive;
Thank you all.

Hi
you must have old buried gold or silver in your field test

test in buried metal my friend not for fresh metal

my lrl

hi
franco I built your lrl
Please guide for getting started.(my frq is 2.8mhz*pot2 set on 6vp-p* led on -off with pot 3)

Please guide?
best wish

Hi mustefa ubram

I repeat here what I said to Hobbit, "you must have a long buried metal that is in same place at least a few months (for my experience) or to know a place where there is surely a long buried metal.

Hi Mustefa Nice work
We waiting you test now. and your news.

Good luck

tank you franco and nicolas
the lrl Reacts to mobile phone radiation.In your opinion, is this acceptable?

[FrancoItaly]

Hi mustefa ubram
I don't know if it's important, I have no tried, but I think that the Lrl is ok.
Best Regards

[mustefa ubram]

franco What are the duties L1 C10 C11 ?
is this circuit postive detector?

[FrancoItaly]

Hi mustefa ubram
I can only say that the phenomenon changes amplitude and phase of the amplifier stage.

hello da italy

NEW VERSION PCB OF LRL FRANCO 6CM*5CM

mustefa hello, I want to ask you a favor, since you've already made the PCB francoitaly I could put the photo in black and white of the printed circuit? I am from Italy as frank I have already contacted him directly, but he told me that he just makes patterns pen and I do not understand nulla.tank

Dear friend

Has i know all LRL divices detects electromagnetics signals from many sources.
Yesterday for example i was experimenting to know what PDK and Crypton OBMD 2 can detect. So for that i try to see if this devices can detect a quarz watch, and yes both detected this small signal. Al so a 1.5 battery, a small tv set are detected. So far i think that the clue is to try the answer from Franco and this is to test the detector on a site where you know there is silver or gold buried from long time (years)

Yes, ok, but I asked for a copy of the electronic board in black and white to be able to do francoitaly and since mustefa already made it like I asked ... mustefa all here to test it then I got it.

[mustefa ubram]

my lrl is ready.But I have not an old metal buried for testingDo not Know

Hi Mustefa nice sensor Antenas
