Good afternoon Morgan! You can find out about the version of the receiving part of the DCX-85 that you use on the LM741?

here some TDA FM radios schematics :

Hello there are two events in the morgan FM receiver. The first is the transmitter, that is, the local oscillator. The second is the buyer duty. Do you know the value of the local oscillator when making your settings? You can understand this with two fm radios. Tune one of the FM radio to 103 MHz and change the frequency of the other FM radio. You will see that the fm sound of the 103 mhz radio is muted.

I had an experience that looks like this , why two fm receiver ?

i tried with one radio that will have the sound cut off at a specific frequency , and after what?

how to use this experiment to detect the phenomenon? I had a lot of theory , and my radio

detect sudden electromagnetic fields at a distance :)

there is a great experience that comes to you after these results, and that is the key :)

If we can determine the transmitter frequency, we can experiment to evoke this frequency golden phenomenon.

You should publish the fm receiver circuit diagram.

brain
03-11-2021, 11:52 AM
The frequency of the fm radio in the 103 MHz transmitter position of the fm radio in the receiver position is around 88 mhz.

abdou2014
03-11-2021, 12:14 PM
what do you mean by ( fm radio in the 103 MHz transmitter position) ?

both radio receivers ?

my experience and results are different from yours, my radio detects the phenomenon and

operates like a BFO and electric receiver

brain
03-11-2021, 12:54 PM
both radio receivers ?
yes.

There is another frequency that your receiver works like a transmitter in the frequency position.

abdou2014
03-11-2021, 12:57 PM
where is the interest ? how used for detection ?

my transmitter circulates in the receiver, and calibrated to a critical position :)

brain
03-11-2021, 01:11 PM
you make another from the same buyer. You understand the event. You set the 103 or 104 mhz receiver, in contrast to the other receiver, when you set it to 88 MHz, the fm sound is cut off. Here we can find what frequency it is, we find the phenomenon value for gold.

From my experience there isn't special frequency for gold etc... (at bands that we can work!!!). There are some bands with better response or lower noise and nothing else.

Many devices are made with frequencies x as if there was a selective frequency for a given substance, maybe there is a certain frequency range for a given substance. Within these bands and dominating its forces the gold will be right there .....:lol:

The frequency of the fm radio in the 103 MHz transmitter position of the fm radio in the receiver position is around 88 mhz.

When Local OSC (Tx) of one Radio is same with input of other FM Radio in Receive mode
(+ some use 10.7Mhz IF ) , So Radio calibrated for Receiver will stopid noise from Speaker

Ok , this is your success , but in me not is so , for full FM sensitive working system it is
only in some special frequency ,
also dear Dubulumatch and Esteban say about special phenomenon frequency in FM .

In my last attempt with FM, the phenomenon burned out the Buzzer floor of my device, I was very surprised .

I can't measure my setting FM receiving frequency , because it is very power low signal ,
, IF of some FM receiver is 10.7 Mhz , IF of AM receiver is 455Khz , This is after
mixing of input and local OSC , but TDA7000 not use 10.7Mhz , only few Khz .

What is the frequency at the transmitter location when the receiver is 80 mhz. I want to design this tx frequency as a transmitter.

brain
04-01-2021, 06:51 AM

oscilator local 98.7-118.7 Mhz

antenna signal 88-108 Mhz

''The local oscillator acts as a transmitter around 10-15 meters''
Yes correct , Local Oscillator also time in all Radios is a mW transmitter .

'' I asked you about the tx frequency ''
The Tx Frequency or also time this is Local OSC freq . in FM radio is so :

This is two kind or type : With Positive or Negative local osc .

1) If you need to hear station in 88Mhz , input rec freq to Radio will be 88 Mhz and local
osc need to be 77.3Mhz ( input freq 88 Mhz - 77.3 Mhz local OSC = 10.7 Mhz need for IF )
also have other method and this is with so :
for 88 Mhz station ( 98.7 Mhz local osc - 88Mhz input freq = also is 10.7 Mhz for IF ) .

You ask about catch frequency of the phenomenon , this frequency can't measuring or is
impossible for today with classical methods .
But for working system need many experiment with circuits and calibration of correct FM receiver Frequency .

Hi Hum Hum nice to greet you again........I also want to ask you the same question that friend Brain asked to you: what do you know about the impact frequency of an X oscillator has any repercussion on the phenomenon or is it only to stimulate and increase the sensitivity of a receiving antenna to be able to capture the phenomenon? ??

Hi dear LRL , my think is that Phenomenon is Photons in Thz Band with small pozitive and
big Negative level energy ( I see this wave in Output of my Mineoro ) , this energy can
modulated itself over many Wave : Hz , Khz ,Mhz ,. Thz .

About X osc , You maybe ask me for correct finding frequency , if is so , this is impact frequency of Gold Resonance ( Mhz Band ) and Esteban use it for Rx near 100Mhz
(Gold Resonance x2 or X3 ) this maybe is from Scalar wave , but this Rx frequency is
(small) different for all Country. Need experiment .

Hi Morgan
The length of cable that you make the 1,5V spark is important. Different lengths lead to different distances. I think it was mr humhum that he proposed a 60cm length as a reference. What was the length of your cable doing those measurements?:)

Hi
It is just a common method to compare sensitivities between devices. Nothing more.
But if it is to compare then length plays a significant role.



Thanks pahom. Very handy.



Have you tried guys to sense a piezo-lighter with your pistols? At what distance do you get the spark?


ps. By the way, rxlock...3,8m..impressive. Thanks

There are many options for Jagu. With a piezo, if you do such maneuvers, then from 20 meters, you can fry the transistors on the go. They seem to work, but they are really a kerdyk. Something like this! So only 1.5 volts is just right. Thank you, THANKS!

Nothing at all.

Catches of spark wiev sensitivity of Your circuit , but this method not wiev that works in real
field .
For example :
Circuit with high sentivity can receive spark from 20m or 50m , but in real field can't
catch from phenomenon energy , because here need real calibration for receive real
wavelenght of phenmenon .
When calibration of circuit is Real , so You can find Big buried object upto ... more meters or
distance with clone Alonso PD , but about Spark only in cm or few meter .

kostas87
10-27-2021, 08:07 AM
if it detects a spark at 2 meters it says nothing about the phenomenon of buried metal, at least for my area. with many hours out and many tests I ended up with a 100nf capacitor in the receiver, and with an RF signal at 2.8khz and 3.3khz to detects huge objects from a distance of a few meters..the spark detection dropped to 60 cm..I think the RF signal is important to increase the distance x 3 times, but if the Receiver does not respond to the phenomenon very close to your area which is the most importantly you will not catch anything with the RF that just increases the distance ..

I do not have access to the secret forum that has a lot of information from esteban etc, but with the tests and some personal expenses I came to the conclusion that it does not take much to detect the phenomenon of the noble metal from a few meters away ... I think you need a sensitive receiver in combination with the sound generator, a BFO absorption system, and a beacon RF circuit and with the right combination can detect the phenomenon ..

The secret is a good design, a carefully construction, a fine tunning and of course a strong phenomenon. Without phenomenon it is difficult to do a lrl to work!!!

Hello to all in this forum, I came here today to informe all of you about some people who are selling Alonso PD clones worldwide for the amazing price of 20000 dollars each one,and the big lie is they said I aprove this LRLs, first of all I have nothing to do with this dark business ,and not aprove at all that kind of clones,since the begining I told the PD is unstable,and its for LRL beginers,a short distance locator. See the photo of this PD clones and be carefull,not fall into this trap,

best regards
hello friend morgan.I can now participate here..Tnx to Qiaozi..I beleived you have the diagram of alonsos pd..Can I have to try it for my project..of course with your help and advices my friend I maybe complete it and try to use in our site..we are currently digging a suspected treasure site with out any gadget so can u help me..Please email me jherickgenova@gmail.com

I do not have access to the secret forum that has a lot of information from esteban etc, but with the tests and some personal expenses I came to the conclusion that it does not take much to detect the phenomenon of the noble metal from a few meters away ... I think you need a sensitive receiver in combination with the sound generator, a BFO absorption system, and a beacon RF circuit and with the right combination can detect the phenomenon ..
Geo:

Geo is correct.
The signal is not a line. It is the electrons flowing from the earth to the ionosphere. The amount of current flowing from the ground to the ionosphere is minuscule at any point on the surface of the earth. However. when there is buried metal that has ions migrating in the ground where it is located, then we see a larger migration of electrons moving upwards toward the ionosphere. The amount of increased electron flow is minuscule, so it is hard to detect. This means we need a very sensitive detector to detect the difference.
(what we are trying to do is use a detector that is so sensitive that it can detect the difference in a location that has double the amount of ions moving into the atmosphere as there are in the adjacent locations). This is a VERY sensitive detector...!
A magnetic wave detector seems to be the best choice of detector, because it is immune from the electrical interference that plagues the skies. However, the increased flow of electrons from the metal site can be stopped if any high energy is injected into it. What I mean by this is... if you were to scan the location of the buried treasure with a metal detector, the strength of the VLF or PI signal would neutralize any ions in the ground and stop the flow of electrons into the atmosphere. This means the target site would be made neutral, or the same as the surrounding ground, so you could no longer detect it.
The moral is: When you build your treasure detector, be careful to not make your simulator coil too strong...!

Thats the truth. Take it or leave it.

VLF or PI detectors Frequency in the HZ or KHZ band, does a high frequency FM, VHF, UHF or GHZ transmitter affect these electrons?

VLF or PI detectors Frequency in the HZ or KHZ band, does a high frequency FM, VHF, UHF or GHZ transmitter affect these electrons?

All energy effects the electrons which are migrating in ions of metals that are buried in the ground. This includes vlf, lf, mf and hf as well as radar frequency. Even light frequency can alter the flow of electrons in the ground ions (light frequencies that are in the range of heat frequencies).
The lesson to learn is to use your sensitive detector of electron flow, and use a minimal amount of stimulation energy. Then you will not deplete the increase of electron flow in the location of the buried metal.

A very well designed detector can find a buried metal without a stimulator. But if a stimulator is used, it will cause a temporary increase in electron flow from the buried metal, so this will allow a poorly designed detector to also be able to detect the location of the buried metal.

If a stimulator is used, then it should be limited to a low power level so it does not cause all of the ions that are in the location of the buried metal to become neutralized. If you send a stimulator signal that is too strong, then you will neutralize all the buried ions, and make the target metal invisible to your detector. The neutralized ions in the ground will look the same as the neighbouring ground which has no buried metal that your detector can find.

The good news is you will see the buried metal has recovered from the over-saturation of injected energy within a few days.
Yes, an over-stimulated buried metal site can recover, and then send out electrons that signal its location....


Hope that helps.

Electrons are generally considered to be negative. But don't let that discourage you. Many people were negative about the concept of a round world when flat was the common belief of the best scientists of that time. :nono:

So if you find some positive electrons, then be the first to report it here in the LRL forum, and we will remember that you deserve the nobel prize for this discovery.

Geo knows a lot of things and I have learned a lot from Geo I do not dispute it..the issue with the distance detectors that we have more or less something that works..but we are never happy..sometimes they do not work well other times they are affected by other signals ..but he is sure that there is always a solution and something that can be made to work very well .

Hi Aft,
Happy to see you are still looking for answers to LRL secrets.

When it power on .. how catch ions ???

The Alonso pistol does not catch ions.
If you examine closely the circuitry of the Mineoro designs, you will see they are capable of transmitting radio waves and receiving radio waves. They have no apparatus which is capable of collecting ions.

This means they can only detect variations in radio waves that are received by the RX coil. Any talk which says ions are collected is false talk.
The Mineoro people have told us that gold ions rise from the ground to 7.21 feet above the ground (see animation below).

https://www.longrangelocators.com/forums/attachment.php?attachmentid=2477&stc=1&d=1184767044

This is false information, the same as the idea that collecting gold ions is a false idea.

The Mineoro detectors are often thrown into the ocean or into trash barrels by people who decided they are not working to find treasures.

There are ions of gold which move through the soil. This is a fact that was proven by Australian scientists, and was later developed into an industry that located gold deposits in the ground as well as other metals like copper, lead, antimony, platinum, cobalt and many others. However, when these metal ions move upward to the surface of the earth, the metal ions in the ground become neutralized and bound to other ions so they are no longer an ion when they reach the surface of the ground.

These are proven facts. However, the LRL companies do not use proven facts to explain how their detectors work.
They rely on stories that have no proof. So you may take your chances to wonder if a manufactured LRL will work.

My advice for people who want to buy an LRL is this:

Go to a large field, about 1 hector or maybe 2 acres size.
1. Bury a gold sample in this field where only you know where the gold is buried.
2. Then bury an aluminum sample somewhere else in the same field where only you know.
3. Then bury a copper sample somewhere else in the same field where only you know.
4. Be careful not to leave footprints where you bury the metals. And also, make false footprints in locations where there is nothing buried.

Then ask the seller of the LRL to come to your field location and the find the gold, find the aluminum, and find the copper with his LRL.
When the seller is done with his demonstration of recovering the metals that you buried, then you can decide if you want to pay the money to buy his locator.

What electronic device do you want to know the frequency of?
The human eye detects frequencies from 430 trillion hertz, seen as red, to 750 trillion hertz, seen as violet. But the eye is not a buried metal, or a manufactured electronic device. So we may look at some manufactured electronic devices which have lower frequencies like toasters, which operate in the frequency range of 30 thz. But even that is too high to detect metals from long range. So perhaps we should look at modern radio transmitters.

They generally transmit between some gigahertz to less than 1 Hz, depending on the application. Most geophysicists look for vlf or ulf frequencies to determine contents under the ground. This means they build their machines to transmit or receive frequencies between 2 hz and 100 khz to detect things in the ground. But remember... their machines are not related to buried treasure, they are only machines that transmit and receive on these frequencies. Any coincidence of finding treasure or gold deposits is simply a coincidence, and has noting to do with the design of their equipment. :cool:

This is because we are talking about electronic devices, not about buried metals.
After all, who would want to use an electronic device to find buried metal? :oh:

the question is simple, on what frequency of reception is calibrated mineoro loop or any LRLs to detect buried metals :froncer les sourcils:
The answer is also simple. The Mineoro and any other LRL is not calibrated at any frequency. The frequencies that are most often measured fall between 3 khz and 180 khz.

But there are exceptions as in the case of the Geo locators and the franco from italy locator, and a few others which operate at higher frequencies. I know that most of these locators are not calibrated at all, but if you want to know for certain, then you may want to contact franco and geo and maybe others who have actually calibrated their machines.

So we see that even a simple question may have a complicated answer... :oh:

The solution is very good components quality. The voltage drift of PS must be lower than 1mv and on base of T13 only few uV. You need a multimeter 5 1/2 digits to check it. After it PD is coming very stable.

Did your PD Alonso also have instability?
In my opinion, the original PD Alonso must also be unstable. In the films that you and Morgan recorded in Portugal.. all the films are only a few seconds and at most a minute... the PD is being processed and explored... there is no film that is being processed and explored for 10 minutes.
Yes, I have very precise measuring equipment.
The use of high-beta transistors in the form of Darlingtons is one of the reasons for the PD's instability.

Morgan said that the PD can detect a coin from 30 cm. For an Omega coil with a diameter of 10 cm, this is an unusual detection distance!!! Did you test in Portugal to see from what distance it could detect a coin?

Did your PD Alonso also have instability?
In my opinion, the original PD Alonso must also be unstable. In the films that you and Morgan recorded in Portugal.. all the films are only a few seconds and at most a minute... the PD is being processed and explored... there is no film that is being processed and explored for 10 minutes.
Yes, I have very precise measuring equipment.
The use of high-beta transistors in the form of Darlingtons is one of the reasons for the PD's instability.

My PD is very stable. I must turn it on and wait for 1 minute, after it i can adjust it and go.
At Portugal our purpose was to show that PD works and can catch the phenomeno. Our interest was not to show how much good was the PD.
The main problem was that it needed very critical adjustment.

Next item. Morgan reads the messages here but doesn't respond.

I think near to 15 cm, maybe 20 cm max. So does mine pd

The long range detection is a very strange thing. Although i have detect many objects with many lrl i can't say with sure "take this lrl and it will work 100%" :angry:

My Alonso circuit on the workbench is very stable.
The instability occurs during the search. The place where it becomes unstable is where the metal is buried.

Yes.
I have fine-tuned the Omega and it detects coins at best from 20 cm. No more.

Yes, I have built several long-range circuits.
They don't always work 100%.
Physical and environmental conditions and weather conditions are important.
