Lrl from Italy

[FrancoItaly]

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

Woooh questa è una buona notizia.
Franco Cosa ne pensi della frequenza del vostro LRL?

This is good news.
Franco What do you think of the frequency of your LRL

[FrancoItaly]

Hi Nicolas
With this Lrl the frequency is about 3Mhz, with the Lrl with the self oscillating mode the frequency is about 5Mhz, then the frequency is not very critical, but perhaps it's critical the LC tank, Rubin had changed L1 with a squared coil with same inductance but with no result. At the present I want to build a PI with a large coil to verify some signals.

thanks

hi to all and thanks master franco your lrl really work l build your lrl project and very good work but l used b548c not work but bc 238and 237 good work with best regard

Hi all
Frankoitaly is correct. My LRL detect my target, but i see last week with hamidity, a big problem with false signals sometimes from east or other address, sometimes for north. In my buried copper franko LRL work, but if i go for tresure hunting, i am confused, because i don't know the real signal
I think need more tests

Thanks franco but strange I think is bad range frequency because we have strange signals we need the best frequency to find treasures.

Look it you can find the best for your LRL

Hi Nicolas
With P1 you may change the Vco frequency, if you use for C11 a 100pF variable capacitor it's possible to find other settings but I think that is very critical. If there are some strange signals it's possible that the gain is too high and the Lrl becomes sensible to compass effect.

Hi franco you are right
But I think change like this picture is better and see what give me

Hi Nicolas
Yes you may try this setting, but my coil antenna have the 2 terminals togheter and this setting change also the phase and the amplitude of the stage. The phenomenon is very difficult to catch and a small change may prevent the right operazion. In a field around my home I have only a not great signal, not detected by MD, and no other signals also with max gain. I'm almost sure that the frequency is not involved in the phenomenon and then L1/C11 tank does match nothing.

Dear Indiana Jones.
LRL franco circuit placed upon the part of the PCB board to the forum here. No part numbers of parts to a PCB antenna where
No matter where the voltage will help bağlancak bellideğil
would be better.
Thank you.

Yes, I know Franco I tested it better before the two terminals together. it is similar to a normal antenna with high impedance.

thanks for your support and help

Dear Indiana Jones.
Can you help me?
Franco started the forum that you send to the LRL track names in PCB
No PCB BOARD forum part number written down again put the amateur here.b please help to make installation of this circuit.
Thank you.

Hi iron1944

I do not understand what you want,all is here in forum.

Mine PCB is the same as Geo post 78

Here's schematic and Materials List from FrancoItaly post 68

My own PCB plan is not finish,I do not know if it works.

Dear Indiana Jones.
Can you help me?
Green color on the PCB board:
NO PART OF RESISTANCE
Diode PART NO
Transistor PART NO

I AMATEUR help me.
THANK YOU.

Mr. Nicolas.
GREAT MASTERS.
