George Hello, you're sending me figure how I made PD detector coil, L7L8 how production, TX, rx how much the diameter?

Can someone who has built the Alonso PD, please reply to this post. Liubing does not seem to understand that I only drew the schematic, but have never built it.

[Geo]

Nobody knows exactly the turns of L7 @ L8, they depended from the ferrite.
Tx diameter is ok for 8...9 cm and 4cm for Rx.

[liubing]

Hello, thank you for your comments on the PD forum, I was doing PD detectors, I do not know the parameters of TX RX and L7L8, L7L8 I did not do that part of the circuit, may I ask what is the function of SW2, G and B are the same is work it, I found it not, no sensitivity to metal, just a little pressure on the TV reaction, ask for your help, I wish you a pleasant

[liubing]

Hello GEO. Please explain SW2, SW2-B, SW2-G's role, I do not understand the function of SW2, and L7L8 that part of the circuit is not it can not also be able to detect? Thank you for your answer

Not many people have managed to successfully build this circuit.

There is one other electronic LRL that I forgot to mention. It is called the Zahori.
Please see attachments. The original article is in Spanish, but I have included a translation in English.

Sw has 3 positions. One position only for the passive receiver, one for the omega circuit and another one for both circuits (passive receiver and omega). I don't understand what you mean about L7 and L8.....

[liubing]

GEO Hello, do you make of the PD detector, SW2 I still do not understand, I do not know SW2-G and SW2-B is not supplying simultaneously or separately powered from my feeling is concerned, it does not have the ability to detect, in fact it is an AC amplifier and triggers impulse, I input signal from the front, did not find its amplification, please explain, very grateful

[liubing]

GEO Hello. Please check you mail, I would like to ask you to separate

[liubing]

I did a PD detectors can only detect the magnetic field of the metal is not reflected in the so-called remote detectors, LRL, PD, are deceptive tricks, we do not have to study, I was doing PI detectors, hope interested friends together to exchange

Here is one old PDK-2 prototype that i can share photo of inner box:


[ATTACH]18389[/ATTACH]

ok,hope you will find something valuable with PDK-2 or maybe the PDK-2.1.

here in advance the INSTRUCTIONS :



PDK-2.1 Electromagnetic Field Locator


Maybe you dont know but one silver or gold object must be buried underground and with SALT ,after that there is a period of minimum 3 years(maybe more,this depends on country,and weather conditions) that the PHENOMENON (electromagnetic field) will grow and the PDK is able to pick the TEST buried object. Recently buried objects not possible to locate,see the forum threads about the tema.

Read carefuly this instructions :

INSTRUCTIONS :

1-The TUNING knob must be all the time on the triangle mark,is the full power,it can be reduced to half only if there are interferences from ground or power lines.

2-The FINE TUNING it must be completly to the left position when you switch ON the PDK , and slowly rotate to the right(arrow direction) until start the beeps ALLWAYS in the referenced marked area,in searching mode the knob must be all the time in the reference marks,then you need to calibrate the LRL to the critical point when your finger touch the knob and emit intermitent beeps it means is ready for search,and time to time check with finger if is sensitive,if emit the beeps,sometimes need little adjustments when batteries go low.
Use ALKALINE batteries,or 9V rechargeable,never 10V batt.
The batteries can stay 2 or 3 hours,check the batt. condition by pressing the little knob,while pressing if RED LED stay open it means low batteries,change batteries.For other new model,change batteries when the FINE TUNING is runing in the RED MARKS.

Very important : when the PDK is ON,your MOBILE must be OFF to avoid interference.
If people stay in front of PDK will mask the buried metals PHENOMENON,people must be behind the PDK,when you searching or pinpointing the objects.
One more IMPORTANT thing about the PDK-2.1 ,never turn ON at home near electricity or PC computer becouse it start beeps crazy locating all this energy,it must turn ON many meters away from electrical equipment and lights,otherwise it OVERLOAD and maybe damage the PDK circuits,or even the high gain transistors burn becouse of the intensive electromagnetic fields very near the LRL .




CALIBRATION TO LIMIT OF SENSITIVITY :
This calibration must be done far from electrical sources(not possible to make calibration at home becouse of electrical interferences),with one hand in the handle ,(the TUNING knob must be in the TRIANGLE mark) and slowly move the FINE TUNING to the right until the LRL beeps intermitent like a sonar while touching the knob with finger. This way is very sensitive.
If this calibration result with erratic signals,reduce just a bit to the left until is stable.But it must beeps when touching the knob.
Is usefull if you searching in remote areas very far from TV VHF transmitters,where not exist RF electromagnetic waves,so the PDK must stay in top sensitivity to pick the targets.


CALIBRATION TO MINIMUM SENSITIVITY :
This calibration is usefull if you are working not far from VHF TRANSMITTER. The VHF waves increase PDK power in 50% to locate the PHENOMENON(electromagnetic field around buried metal) of GOLD/SILVER buried objects.
Also this calibration is very useful when you searching in places where there is ground or transmitters interferences that make the PDK unstable,using this calibration is very stable,it will emit beeps only for gold or silver metals.
The PDK is tuned with frequency to find only noble metals .
This calibration consist in keep the FINE TUNING knob to emit only one beep when you touch the knob with finger,the capacitance make the circuit to emit ony one beep when PDK is sensitive,or many intermitent beeps(like a sonar) when is very sensitive.


Objects distances and deep :

very old coin - 8 m distance, the maximum reported deep was 60 cm

large object 20X20cm - 80 m distance,the deep can be even more than 5 m.
However ,this performance depends on countries,where this can be more distance or less,it depends on unknown factors about the PHENOMENON.
Report from Serbia said the PDK cant locate small coin,however other report from Greece said one small silver coin was found 10 m distance...

NOTE:

More time the object is underground,more intensive is the electromagnetic field around object,more distance will be located. ///////////////////Objects buried less than 20 years ago are not possible to be located.//////////////////////////////////
Searching in fields worked constantly by tractors is not possible to pick targets(electromagnetic field was destroyed) ,however is possible to pick the tagets below the tractors worked area,or places where the ground was not touched.
About the best weather conditions,PDK can be used with all weather conditions except when is raining days, high humidity can damage the circuits or produce interferences.
Sometimes the gold/silver emit the signal in only one direction. The field with interest to search must be worked in all directions, North,South,East,west.

You will know when PDK is locating Gold or Silver,it gives more than one beep in the same direction,and you can folow the beps until arrive to the spot,then if is dificult to PINPOINT with the LRL PDK,use the metal detector,if is very deep dig the ground and try again the metal detector,once the object is out from ground,the PDK will not emit beeps becouse the ELECTROMAGNETIC FIELD was destroyed when digging the ground around the object.

When using the PDK-2.1 in fields,its normal to hear some sparzed beep,becouse of other low conductive metals underground(copper ,bronze,brass etc) that create very little electromagnetic field and anomalies in the ground,but the high conductive noble metals Gold or Silver it emit much more stronger energy and are located very easy with the PDK receptor.

Hi dear Morgan
Saw this comment here and request schemas as well as from most problems with their territories.
and I saw that you do not pouver produce more than two or three devices in one month.
so you're a designer and you updated 3 or 4 types of PDK.
and you said that even copies of your PDK does not work well.
So I have a proposal for you and to help other people to do his PDK
to give them at least the first scheme first PDK 2.1
And that I do myself. in my LRL. I give the free version first. that can make the first version, can also last and update.

becaufe it there's a proverb "Thing does not have No Gives "

and thanks for all we are all researchers and also poor patients by Gold

The PDK-1 project is available for everybody in the RS forum, that is the best i can give,and every one can modificate or UPGRADE the circuit.

PDKs are LOW COST LRLs that work much better than EXPENSIVE LRLs in the market.

Hello

I decide to put here the news of a GREAT TREASURE OF GOLD COINS found recently in Greece with the PDK-2.3 model, this is not propaganda for sale PDKs, its the amazing find of a ceramic pot with a hoard of gold coins.
I stay silent about WHO FOUND the hoard, but it is cientific evidence that the gold inside sealed ceramic pot also irradiate the PHENOMENON.
About DISTANCE and DEPTH i dont know yet,this is today amazing news.

Regards all
