Real clone Alonso-PD

[ANDREAS]

Hi all
PD only for Gold it's ready. Need only final test this month, of course with videos.
I use only one stage from original PD Alonso nothing more.
Very small size and weight, full stability without humidity problems or sky-grounds effect.

Now need only fine weather and small free time.
Note: For now it remains a prototype, I have not decided yet what I'll do
best regards

hi alonso
Congratulations
Excellent device and without complications
As for me, I still have not succeeded in the first device manufacturing, is still the problem of discrimination
He works as a pulse induction
He also works with a transmitter as in this Annex video

Thank you to the spaciousness of your chest

Hi Nicolas
Is very clean
JI (on PCB) is for connection batteries (two serial 9V=18V)
Trans (on pcb) is for connection +/-9V transmitter
Later i publish all connection with a diagram

Hello Andreas do you have all conections?, when you put the interconnections of all the elements of PD to see where I'm wrong.

Already I conected all pd elements but does not work as I interconnects.


how do you see the image of the interconnections present here of the wires going to the receiving antenna seems that there are good?

what about the zero point calibration must be done first of all of the transmitting and receiving antennas if everything is connected directly and in conjunction with the ferrite? that is where I have the problem.

LRLMAN.
Need fine tune all coils a central frequency by Tx coil and next step zero all together. If you find the best point setting ferrite coil (this is so difficult), you must try find the place for Rx coil and ferrite together for same output signal via ferrite circuit and MD circuit. If you can see my first video i use screws calibration for finding the place. It's difficult, because need critical place +/-0,5mm up-down front -back for all coils

And what about the interconections of all elements?? are fine?? respect to the image???

I don't know how interconnected the TX and RX, for me it's not good the image, i have a problem mi PD not work.

And what about the ferrite?, how can work the ferrite? do you think if i make a short circuit with a 1.5 v, should detect it the ferrite? to know if this is working?

May be tomorrow I upload a video of my Pd Working.

OOOOOOOOOOPSSS,

I DID REVIEW ALL INFORMATION AND NOTHING, JUST I DID WORK THE OMEGA COIL, BUT I ASK IF ANTENNA FERRITE MUST ALSO BE WORKING?? I REVISED ALL COMPONENTS BUT I THINK MISSING SOMETHING MORE BECAUSE THE FERRITE ISN'T WORKING.

IN ALONSO PD IS EASILY TO KNOW WHEN THE ANTENNA FERRITE IS WORKING WITH ONLY MAKE A SHORT CIRCUIT 1.5 BATTERY WITH A ROUND WIRE 20 CMS. LONG, OR WITH A TELEVISION REMOTE CONTROL, BUT IN THIS NEW PD NOT HAVE ANY SIGNAL WITH THE SHORT CIRCUIT AND I THINK IF IT IS NORMAL ????

SO WHERE IS THE ERROR?

IN THIS NEW PISTOL DETECTOR I NOT SEE WERE HAS THE SWITCH POSITIONS ONLY FOR FERRITE OR JUST OMEGA OR BOTH.

ALSO I THINK THAT YOU NOT BEEN CLEAR ENOUGH, BECAUSE ONLY THE MEMBERS OF THIS FORUM ARE SUGGESTING ALL WITH IMAGES, WITH LEGEND THE POSITIONS OF ALL COMPONENTS OF THIS EQUIPMENT AND THE PROYECT IS YOURS AND IT IS NOT OF THEM.

SORRY ANDREAS.

[ANDREAS]

Hi LRLMAN
I build clone with all parts, all stages as you know and publish here.
Calibration is very-very difficult and critical
If you have not tune all together this PD cannot work.
i see clone can detect a spark only 40cm distance , a magnet near 50cm distance and ofcourse metals on air maximum 20 cm distance.
TV control i think detect 20 cm distance
Now if you want work with only feritte, if you want detect a spark xxx distance, this is your choice build it.
For me is a pratform for better results
About if i am clear or not
Ofcourse i am clear. ofcourse i publish my first unit here and i say this is a real clone with small mods for better stability. ofcourse i publish here a fine PCB for all members if they want build and experiment with this.
Now if you want method for full calibration or more, i think some members publish here can build this. In this case you can ask there
Now about PD only for Gold
I use only one preamp stage by clone alonso and new circuits by me (you can see my last photo inside PD only for Gold)
Pd only for gold cannot detect metals, cannot detect sparks, cannot detect magnetic lines etc
I am very clear. I publish here a thread "real clone alonso PD". I don't publish here a thread " how you can calibrate and build a clone alonso for your step by step".
In this case some extra infos via my posts is a gift for every one try build one

Hi Andreas , maybe Now I understand what is Secret for this PD narrow band gold filter for very high frequency.

[king40]

this pd is free or for sale ?

[ANDREAS]

this pd is free or for sale ?
Alonso PD is free to manufacturers or anyone who wants to try construct it.
My presentation of this PD was done in same box shape as much as possible dimensions is what properly, with the original schematic and very small mods for more stability. Of course I use the same box as "platform" for my PD only for gold.
After finish all experiments and anything need more, i put PD only for gold in a new design box . PD only for Gold is not free

Ok Thanks
for users like me , that no have any experience in pd , build this pd is very hard
best way is by pd

[paku]

Dear ANDREAS
how much the price you sell this pd

[ANDREAS]

A fine circuit, need and special case, for ergonomic search and easy calibration by user. In this case i must draw a new box for put all electronics circuits, ferrite etc. I think after ten months am ready with new design circuits as you can see, my post #218.
I don't use the original PD box, because i don't like this classic design and more ,because i have problem with with vibration between base "coils housing" and main box.
Need only fine weather for external tests.
Inside lab PD can detect very easy Gold if put a place after 30 minutes. Very delicate unit, produce a "trust" by user via calibration and see with eyes the real detection Gold.
Need small time for solve all small problems
enjoy

Very nice looking instrument, and it's tall (like TOTeM). However, the handle on your PD is better positioned for stability. :)

Many times i have in my thought your design-box, because is stronger for use and better protection coils vs vertical setting ferrite.
You are right. If you think my design-box make a "confused" or you think... i make it without your license, please inform me for change it.

Hi Andreas,

Absolutely no problem with your design. There is no conflict with TOTeM.
I was just admiring the way you repositioned the handle for better stability.

Well as for the center of Gravitate if the handle is in the center and not in the face is so easy.

Not be worried Andreas do as you like without recourse to the permission. I even thought to divide your box into two, but you did it before me. OPS Then again i need ask permission from you.? I know you not give it purpose I build it without problem .... thank you Andreas this is life :D:D

Hello Andreas.
I tested my PD on real object from 4 years ago in 2m depth.
It can detect signal from 7 m away from target .
See it from here.

LDX is designed for gold but it can detect other materials like LEAD too.
You can see my test from here.
Also i tested PD,Mole prospector,ldx with the same results
LEAD is about 5kg in 2m depth and from 4 years ago.

Thanks for your opinion and idea.
I will do more tests and let you know.
Max range on big object is about 20m and max depth is 6m.

Dear ROJ,

Since you have a Mole Prospector, it has proven near some appliances (refrigerator, TV) to see if it also reacts?

Using the Mole Prospector as sensor? is an elongated antenna?

Honestly, I would forget about the Alonso PD. There are too many unanswered questions for you to be sure that you've made an exact copy.

I would suggest building TOTeM, which is fully documented here ->
http://www.longrangelocators.com/forums/showthread.php?t=19245

At least you will be able to determine if it works as designed or not.
As stated in the Conclusion:
"Unlike the original PD, the TOTeM project is easily rep-
licated with a little care and attention. It easily passes all the
laboratory-based tests used by LRL experimenters, and cer-
tainly appears to react in the same way as the device shown
in the internet videos. Whether it will lead you to treasure or
not is maybe another story, but at least you will have the
opportunity to explore the pseudo-scientific world of long
range locators for yourself, and make up your own mind on
the matter."

soo...this clon alonso PD is not work..if i made..so tell me is true is work or not.thank

Alonso's PD works for sure, i made tests at it (the prototype), but there are some hiden secrets. So nobody measured the coil of ferrite coil, the frequency of passive receiver and the distance between two ferrites.

[abdou2014]

We don't know these secrets and nobody will share them with us, so why get tired .

When i wrote "distance between two ferrites" i meant the gap between the ferrites.

The same way as you tune DD or OO coils at VLF/IB detectors.

Read about such coil tunning at Geotech forum (TGSL project par example).

You you need to search zero signal at scope (coil nulling) by carefully mowing small middle coil (RX) over "inner ear" part of bigger coil (TX).

What sort of scope do you have?

In general, with signal tip of scope probe you check certain circuit test points (I propose you 6 specific test point in bottom attached PD circuit)
to check individual circuit stages on working status (red line is of scope probe tip - ground probe clamp is always at the same point/ground).

Ground clamp of scope probe should go to circuit ground for check of all marked test points.

You need to set proper vertical sensitivity (voltage per division) in scope channel used and proper scanning time.

You should follow the same test logic (test on working specific circuit stages) with all circuits/schematics.

i want found zero signal in rx coil

[WM6]

CH1 probe to RX coil wire (probe tip to blue wire, ground clamp to black(ground)) wire.

Tunning (nulling) perform by carefully small mowing coils sections apart to each other.

CH2 probe can be attached to TX coil wire to mutual control of TX stage working.

Hi all

After three years of testing experiments etc. PD only for Gold is available on the market. This PD have two models.
1. PDGOLD for detection only for gold and Gold-alloys.
2. PDSILVER for detecting only silver and silver-alloys.
For more information you can visit our site www.crypton.com.gr (http://www.crypton.com.gr)

Hello Andreas I have a question about Alonso PD'S....do you know if the alonso pd must be a Magnetic??? or magnetic receptor???

If it must detect magnets or magnetic fields and at what distance should detect small magnets and if the electrostatic ionic phenomenon has a strong magnetic component to be detected at a certain frequency and some distance by the Pd ??

Best regards.

OK thank you very much; I ask you all this because I have some doubts regarding the true LRL of Alonso which has brought to sell to mexico to some friends searchers and which we have tried with success in some searches in Mexico and I have seen and I have tried these devices and i put a magnet in front of them... they can detect any magnet at close distance and can also detect any source of energy at a short distance with the exception of the Tesla coil which is more an HV emitter and infrared receiver.

Maybe Andreas put a different pcb when he take pictures of his PD. Take note that His PD is already for sale at high price. Do you expect him to give us the correct modification? I'm sure not. The picture is not the original Alonso PD but a general modification.

I can not calibrate coils, I need ideas, comment ...

[GOLDEN LILLY]

According to Andrea's calibration procedure, you have to move the ferrite first to find the null, then null or adjust the Rx of the omega until both the ferrite and the Rx nulls. Repeat this procedure to obtain the best position of the null. I do not know if this is the correct procedure but this is the tips he gave us. I do not even know if which either the rx coil or the ferrite are responsible for the long range detection.

The problem I have is when I point it to the ground it beeps and when I point it to the sky it beeps. Detects a coin in front of the omega coil, the ferrite antenna can detect a TV. The circuit is correct but I think I have some error that I can not correct.:angry:

I think Andreas is sharing much of his knowledge and research he has done with the LRL, it is true that he does not share 100% but we have to investigate and test. Resonating coils is very complex, you need to do mathematical calculations and help test meters, coil ferrite is more complex because it Slug type coupling coil (coil resonances / main coil), of course we need sometimes a help To advance our projects. This is a hobby and I would like to finish it.

Mr Andreas I have a friend who bought you Krypton 4, but the device does not produce a sound but the last rotation variable resistance Kalk reveals the television screen and mobile voice on them! Does the device need a balance like this? Also, do not reveal the gold bracelet of the caliber 21 to close to him or not hope to send me or put a video showing how to balance and thank you

[brs]

I am sorry, my English is weak. I use the translator. I mean, it shows the sound, but in the last rolls of variable resistance to the right, and when the sound is heard, I go back until the device calms down and in this case the TV screen and the mobile phone and the palm of the hand are detected if I approach the front shell to detect the gold and when I return the resistance to the left more Silent and do not reveal anything I ask perhaps he needs to balance it, but we did not watch a video of how to balance the correct

The RX coil probably is based on the Alonso PD ferrite configuration.

seems to be interesting, but does it discriminate against non-ferrous metals?

[Farid]

Yes, it's a lot better than non-ferrous metals. In this case I will publish a new movie.
If the ferrite is not adjusted properly, it does not make any difference between the metals, but if properly adjusted, the non-ferrous metals will have the best reaction and will react to poor ferrous metals.
Come to see our videos on our telegram channel.

As I said, I can not know what kind of metal is because it is located below a large round planter and I can not destroy it.

And the PD, must be connected the ferrite-omega together.

The only position of omega working how a metal detector.

Does anyone know the inductance of the ferrite coil?


Inductance of the ferrite coil and paralel capasitor to him You will set for around ( the nearest ) Radio station

for example : ( the nearest ) XX Radio station transmitt in 59.941 KHz , now you will set your Receiver coil for him with this calculator.

https://goodcalculators.com/resonant-frequency-calculator/

[abdou2014]

you mean we set our LRL near Time signal frequencies ?
and how for those who are very far from Time signal broadcast ?
can we set our LRL on LW radio station ?

[humhum]

you mean we set our LRL near Time signal frequencies ?
and how for those who are very far from Time signal broadcast ?
can we set our LRL on LW radio station ?

Yes, if you can receive Radio station with your radio device in your around , for LW if, signal is wery strong also , Yes .

[abdou2014]

I think we do not need stimulation if we have the ability to detect a radio station with our LRL, do you have the same opinion?

[humhum]

I think we do not need stimulation if we have the ability to detect a radio station with our LRL, do you have the same opinion?

No , I not think so ,Stimulator is other story .

[abdou2014]

I built a very sensitive LF LRL, I can search with a variable capacitor between 50 and 100 kHz, it captures any station a hundred miles away or very weak electric phenomenon :cool:

[abdou2014]

I know that the stimulator increases the sensitivity, but if your LRL is very sensitive, no need

[humhum]

I built a very sensitive LF LRL, I can search with a variable capacitor between 50 and 100 kHz, it captures any station a hundred miles away or very weak electric phenomenon :cool:

But Received signal of any Radio station is only part of PD, after this you will need set many critical adjust with it.
And LW radio signal is with very noisy , it's hard to work on it.

[humhum]

without coil paralelle capacitor and without stimulator it detect sparck 1.5 battery from 1.2 meter

spark from 1 meter is good , but You test it around one buried metal , if you not have so place , You can buried of your garden one precious metal and will wait for many time for test with it. This will be Real Test of your Device.

why without parallel capacitor the distance is 1.2 meter and with the capacitor it decreases?
I need a stimulator schematic ???

Good day
As many, interested in ? Alonso PD ? which is modified and dedicated by Mr.andreas Christi
Built one and studied.

Above all, I must say that Mr.anreas Christi from Greek is an honest, hardworking, social person and his device works, but I think works regionally. Depends on conditions.

Here is the result:

Alonso-Andreas PD can NOT detect either old buried or fresh gold target from far in any regions or area.
There is NOT any zero or magic or golden point which can be tuned by plastic screw or other micro stepping adjustment technic.
Ferrite rod and a coil, obviously result a radio signal receiver and Mr.christi accidentally
Is receiving some sort of signal (probably UHF) which has effect on Gold target. PD transmitter has NOT effect.
What does it mean? If you notice to recent product by Christi (pocket gold detector), it is just a receiver In UHF band and has no transmitter.
Means, if you live in an area which there is not any UHF band signal transmitter, your PD can not detect any gold target from far.

PD transmitter produces approx. 180 KHz sinusoidal frequency. (it is much like damped wave)

Receiver by capacitor value in schematic, tuned to approx. 77 KHz. (75 KHz to 79 KHz variable by moving coil on the rod)
Do you see any relation between those numbers? (personally I do not)

also there is a 15 Hz low-band-pass filter in the receiver circuit which does not let other higher signals pass to detection part.

Overall, do not know what UHF frequency has effect on fresh and old gold target and why this Contact produces 15Hz and below. (beat frequency or ?.)
But I think without UHF in your area, no hope to your PD able to detect gold.
as myself in iran-shiraz city, which since several years ago, UHF signals stopped by TV channels and all became digital.
Also, I informed that there is no UHF TV transmitter in the middle east. at my country very limited Still in the capital. Other area is empty. So, not only your home-made PD will not work in all regions but also factory-made may not work.

Important: UHF concept and effect, borrowed from andreas Christi videos published on youtube.

Any comment, appreciated and welcome.
Please correct it if I am wrong. Thank you

[behnamvp]

according to its size , I'm sure it's an IR optical system !

according to a the video that andreas presented and showing device performance,
it is not IR optical detector. he says device uses UHF band and by noticing to video,
it is clear that the detector is just a receiver which i think it uses available transmitted
radio signal in the environment. TV stations transmitter signals or other sources, i do not know. but it seems to be RF receiver.

[behnamvp]

Does anyone have inside Photos from PGF 170, for analyzing Works method or prencibe ??

Can share here ...

unfortunately, couldn't find any picture.
but we can guess some
there is a knob on the box and first he turn it until tune device
the position of knob is seems to be variable capacitor such as available in MW or SW radio.
also he says if gold target is less than 5 gram, device can not find it
seems density of target is matter and size of surface is not important
also he says it is short range detector something around 2 or 3 meters from target
when put these signs together, i think the result is a kind of RF detector which uses
high power signals which transmitting by radio or TV stations

[humhum]

Why You thinks that use UHF freq. , can also use so like RF receiver MW or SW band ,

İf this Detector is from only UHF Receiver , then will use any UHF fix Freq. and special Filter only for precious Metals , I think so .
And knob can Variable Cap or Potans for Threshold gain .

[behnamvp]

good day

Here are a few measurements. hope to be useful for who interested to study Alonso-andreas PD.
Please notice that written values are all approx. values depends on ?measurement device?, ?how to wind coils? and ?what size of wire used to?.
Anyway, in any condition, I do not think the result will be out of the ?given range?.
It seems presence of ? UHF ? signal is vital for device to work as a long range gold detector and Just by making and assembling, device just works such as normal metal detector and not as LRL.

Once again: the UHF influences is taken from a video by Mr.andreas Christi, which is about ? pocket-size remote gold detector ?. This video available on youtube at his channel.

Here I must say: many thanks to Mr.andreas Christi from Greece also special thanks to Daniel for wiring diagram.

The PD detects massive metal targets (like cars) from a medium distance? say 3-5 meters.
Also when it finds a good old target, if you hold it stationary, has signal?

adjustable between them

those who manage to calibrate at 66khz will have success

Good day
66 KHZ receiver or transmitter?
if you notice to values given and written on the schema, by calculation other frequencies
will appear. practically as i measured by oscilloscope, not much difference in calculation
and in performance.
something is missing in alonso-andreas PD. there must be an "extra factor" which has crucial
influence that PD need it to work and detect even fresh gold under ground.

here you can see 181 khz which measured by oscilloscope.my device

I'm not really a big fan of the Alonso PD , and I know the basic info about this detector ,
but I don't remember Morgan or Esteban saying that this PD detects fresh gold.
(is here, in this forum, or elsewhere, such a statement from them?)

[Morgan]

the Alonso PD locate a gold sovering 8gr in air test 30 cm

thanks for the info Morgan.
Personally ,for sure, I would not classify this 30 cm, as a long range detection.

this is AIR TEST on a gold coin, if the same coin was buried in the ground for 10 years ,get 3meter, 100years maybe 10meters,

see distance I get in a silver bracelet buried at 40cm 7 years ago, 6 meters

I'm talking also for the air test.
To be more clear, 30cm detection distance on air test, it's not a long range detection for this "fresh" gold coin.
Simply it's the expected distance from a typical metal detector.
In my opinion, Alonso PD is not a "fresh gold" detector, regardless of the advertisement of some clone makers.
