hi to all
This is a VLf receiver circuit.
I want to know you can help the client to the remote location of metals in soil?
What works in the frequency of this receiver???
Can be used instead of the telescopic antenna for greater sensitivity of the antenna coil?
with respect

Instead of telescopic antenna you ca use more directive ferrite antenna as on drawing.

Frequency in VLF band is of your choice, you can set it by proper Lx and Cx. Use one of online resonant frequency calculators.

If you wound Lx to 57mH then

with Cx of 100uF you get 66Hz and

with Cx of 1uF you get 666Hz and

with Cx of 10nF you get 6666Hz and

with Cx of 100pF you get 66666Hz and

so on.

You should try different capacitors to establish best detecting frequency in your location.

Yes, C1 and C2 remain in circuit.
It is the same if metal is new buried or old in soil.
It works as VLF receiver of Earth signals.

tank you very much wm6
I read this thread.But did not answer the question:
1-What state is called the frequency?
2-If the antenna is wrapped as a Tesla coil?
3-This circuit can not detect metal with dimensions 20 * 20?
With great respect for your professor wm6

[WM6]

1. I do not understand your question, dear academic.

2. Ferrite antenna is wrapped as ferrite antenna (here with more turns).

3. 20x20 plate can be detected - at which distance depend on many factors as tuning at best Earth signal frequency, target orientation and position regarding signal source, signal beam input and reflect angle etc.

Here we can detect by signal changing on signal reflection and by signal shadow.

Dear colleague professor jack.
My English is too poor to understand all your question.
The best way to get answers is to build one (parts needed are very cheap) and test it.

WM6 is correct.
This detector is a VLF receiver which has been modified to use a ferrite loop.
The original design before the Arial version or the ferrite probably used an air coil loop.
VLF receivers are known to be good to map buried objects which are large, such as large rock formations, or sometimes very large objects such as a buried car.
The ferrite modification is expected to modify this detector to allow finding smaller objects. It may also reduce the maximum range of detection.

All of the VLF locator projects we see in this forum are only experimental designs which people build to see if they can improve the performance of a vLF receiver so it can be used to locate smaller metal objects from a distance.
None of these have been shown to have any consistent abilities to find buried jewelry or treasures. They are simply experimental projects to try to see what we can find.
There is no data base for what depth we can expect for the design shown above, because the performance depends on the details of how the circuit is constructed and how it is used.
And the performance also depends on what kind of soil it is used in and what is the moisture content, and what VLF/ULF noise happens to be in the area where you are hunting.

The only way to know how this circuit works is to build it and test it to see for yourself.
If you are not satisfied with the test performance, then you can modify the circuit to see if you can improve it.
This is what every other experimental VLF project builder here does.

Best wishes,

Are the frequencies of all elements of their basement?
Are Sense and it is by the vlf reciver?
Frequency difference between metals and other elements in what is understood and how?
Do you have metal in the basement, each with a specific frequency?
In what part of the circuit operating frequency can be measured with a frequency counter?

I know of no VLF frequencies which are for different elements.
The experimenters who are using VLF receivers to locate metal are using frequencies between 40 KHz and 180 KHz.
They say the frequency does not make a difference for different metals.

For VLF penetration into the ground, the lower frequencies can penetrate deeper than the higher frequencies.
But lower frequencies are not able to find small objects as well as higher frequencies.
The best compromise which experimenters use is 60 Khz to 120 KHz.
60-120 KHz frequency range is able to penetrate the ground maybe 2-5 meters deep for a VLF transmission.
If your receiver is set in this frequency, then you will need to have a VLF signal in the air to receive.
This means you will need to have VLF noise or transmitter somewhere making a radio signal for your receiver to tune to.

If you expect to find metals from only special metal frequencies of elements, then you need to find instructions from some different person.
I do not believe you will find a frequency of different elements to be detected with this receiver.
I think you will find only radio transmissions and radio noise.
And if you are lucky to be tuned to a VLF transmitter frequency, you may also find some indications of large buried things in the ground.

Total to you Can I modify the receiver to detect metals that wm6 remote use?
The circuit itself is able to detect small metal on earth?(with ferrit coil)
you believe a frequency of 60 kHz to 120 kHz can be set to find a suitable metal?
The receiver with ferrite antenna you can make clear whether the metal in the radial (What size is the smallest possible metal)?

No the circuit by itself with ferrite coil cannot detect small metal on the earth.
In order to detect small metal you must also have a transmission of the frequency which you are tuned to, and you must hold the ferrite close to the small metal.
If there is a VLF transmitter sending a radio signal which you can tune to, then if you are lucky, maybe you can locate large buried things from more than 1 meter with this receiver circuit and ferrite.
Geologists can locate large buried things with a similar receiver when there is a VLF transmitter located 300 miles distance or less.
If there is no transmitter sending radio waves for them to receive, then they must set their own VLF transmitter to send a signal for their receiver to receive.
They usually put a very large loop of cable on the ground to transmit their VLF signal, then they walk inside of the loop to look for things buried.

These geologists do not find small metal things, only large things like rock formations, and sometimes large buried metal tanks and other large metal things.
They use large air loops maybe the same size as a large metal detector coil to find large things.
But experimenters use ferrites to keep the searching receiver coil smaller and to search for smaller things.
The experimenters also use higher frequencies than geologists so they can find smaller things.
Experimenters do not use 5 KHz to 30 KHz which geologists use. They use higher 60-120 KHz.
Nobody can say what is the smallest size metal you can find.
The only way to know how small metal things you can find is to built the receiver and tune to a frequency where you can receive a vLF transmission.
Then test to see if you can find large things or small things.
If you can find large things, then keep looking until you find smaller things.
After enough practice you will know what is the smallest thing you can find.

Some people say you cannot find anything with a VLF receiver.
But I think you can because I see publications from Geologists who find things buried when using a VLF receiver tuned to a VLF broadcast.

Hi D-man,
I am not talking about theories.
I am stating facts.
It is a fact that geologists use VLF for locating things under the ground.
We all have known this fact for many years.
This is not a new advance in knowledge.
You can see my early 2006 posts in Geotech forum where I argued with Carl-NC to say that gold can corrode in tiny amounts when it is buried in the ground.
http://www.longrangelocators.com/for...1392#post41652

I say the same today as I said in 2006.
What has changed is that the SGS company has performed thousands more tests since that time to prove that gold forms ions in the ground.
So I see the chemistry for forming gold ions is slightly different than I originally thought.

You will see I have not learned new LRL pseudoscience.
Nobody has been able to teach me that buried treasures resonate to a frequency that I can tune with a receiver and locate the treasure.

I have one LRL on loan which does not help me to locate treasure. Nor does it help anyone else who tried it to locate treasure.
So I learned nothing new except what some scientists teach for buried gold.
Maybe Crypton company will show us a good LRL that can be used by anyone to locate buried metals.
We must wait and see.

Yo no estoy hablando de teorÃ*as.
Yo soy exponiendo los hechos.
Es un hecho que los geólogos utilizan VLF para localizar las cosas bajo la tierra.
Todos hemos conocido este hecho desde hace muchos años.
Esto no es un nuevo avance en el conocimiento.
Usted puede ver mis mensajes en el foro Geotech (año 2006), donde discutÃ* con Carl-NC a decir el oro puede corroer en pequeñas cantidades cuando se entierra en el suelo.
Mira aqui: http://www.longrangelocators.com/for...1392#post41652

Yo digo el mismo hoy como lo que dije en 2006.
Lo que ha cambiado es la compañÃ*a de SGS ha realizado miles de pruebas desde el año 2006 para demostrar que forma iones de oro en el suelo.
AsÃ* que aprendÃ* la quÃ*mica para la formación de iones de oro es ligeramente diferente

Usted puede ver que no he aprendido pseudociencias nuevas de LRL.
Nadie ha conseguido que me enseñe que los tesoros enterrados resuenan a una frecuencia que puede detectar con un receptor direccional para localizar el tesoro.

Yo tengo una LRL en préstamo que no puede ayudarme a localizar cualquier tesoro. Tampoco puede ayudar a cualquier otra persona que trató de localizar cualquier tesoro.
AsÃ* me enteré nada nuevo, salvo lo que algunos cientÃ*ficos enseñan de oro enterrado.
Tal vez la compañÃ*a Crypton presentará una LRL buena que puede ser utilizado por cualquier persona para localizar metales enterrados.
Debemos esperar y ver.

Abrazos
