Lrl from Italy

[abdou2014]

Mr Franco , The Sky and Compass Effects can not be with a tiny antenna like L1 ? I increased the maximum gain without having, how did you get it ??

[FrancoItaly]

sky and compass effects are always unwanted, but are useful to adjust the LRL to the maximum sensitivity that corresponds to the point before the start of the effect. To get what decrease the value of R10 in the version with 1 LED (from 220K to 100K or 47K) or in the 3 LED version change R1 from 150K to 100K and R2 from 220K to 470K. It is possible that more short antennas are less susceptible to the compass effect.

The same with the 8 mhz schematic

[abdou2014]

thank you to all

Real distance,it is the same video 1and 2 part

hi taxma
did you check to detect what is there buried and depth of the target? (In these video)
thank's

Good success friend i m happy for you

[taxma1981]

Thanks nikolas,I put no disk at this point,4 years before I found a gold earring in this area

[abdou2014]

Congratulations Taxma

Congratulations Taxma.
Question now is if you are going to share with us, details of your circuit?
If your answer is yes, you will be the first good man who can really share real LRL.
We also must thank Franco for his support and dedicated time to help us build this unit.
I have build one unit, but not finish jet. So i will continue my work in a few more days.

Good test, excellent video and thanks for sharing.
Regards
Nelson

Nice video taxma.

I made the same lrl but difficult to pinpoint the target and only two directions it will beep from NW and SE. Lowering the antenna to pinpoint the sound disappears. At least i got the idea from this video on how to manage to pinpoint the target.

thank you very much, and of course I want to share the circuit, it is not secret ..
I do experiments on two receivers and I see differences, the circuit I made is the crystal 8 mhz, another that also works well is one battlfield laser detector with the difference that at the entrance we have a crystal oscillator as well as the same circuit Lc Franco ..I am not my good acquaintances but like doing experiment

[taxma1981]

From lrl franko i use this circuit

[taxma1981]

It is important the LC circuit to tunning to a radio station of your area

[nelson]

Thanks taxma. So you did 8 mhz stage, plyus an amplifier stage, correct?

I do not understand well, I mean that this project with an oscillator and the circuit lc Franco WORKED ..
Can someone fix it properly the changes;

Thank you for your cooperation taxma1981, but personally I did not understand exactly what you did.
is what you have modified the schema Franco Italy or what ????

[taxma1981]

Franco's plan does not hurt, it works

[abdou2014]

Mr taxma , can you share with us your PCB

[nelson]

Hi Taxma.
What i mean, if you build just franco 8 mhz circuit, or you build it with an extra circuit or amplifier to allow it to get more sensitivity.

Franco, can you tell us if you understand what did Taxma to the circuit, is there another stage that allows it to get the signal from far away?
Ina advance many thanks
Nelson

It is not very clear, but surely this is not only my LRL, I think that the operation key is Tr2, where the "phenomenon" interferes with 8MHz signal which is then amplified.

Hi again and sorry for my englisch,
the additional circuit is not for the circuit of Frank..it is for the circuit battlfield lazer detector...this circuit with a crystal oscillator and a LC circuit working well.....
