PDK inside

[GOLDEN LILLY]

Hello morgan, just to ask you few questions on the pdk i built following you coil information, that is 40 turns, .30mm wire and 6 cm diameter. I tried 2.2n to 12n capacitors but it is less sensitive. I am referring to my crt tv as initial test since my buried target is still one month old.
I experimented several capacitors and found out that lower capacitor value just like 500 picofarad or lower, the pdk create a strong capacitance that touching the potentiometers, that is, the gain and sensitivity it will beep. The same is true also when my hand is near to the coil, it will beep. Also, a quarts watch at 5cm can also be detected. Those findings did not happen to the capacitors 2.2 to 12n. I also found out that placing the sensitivity knob to its proper place is very important.
According the instruction on your pdk, the point of sensitivity is reached when a beep is heard by touching the knob and turning the sensitivity to its triangle mark. So i think that capacitance plays a role of the phenomenon detection. Please comment...

PDK capacitance and coil tuning

yes, the PDK is hard to dominate becouse of the high level of capacitance, however once you find the right place for the coil you get it mastered.

Since some people decide to expose the circuit of the PDK-2.1 model, the unique secret that remains is HOW TO TUNE THE COIL, for this process you need to build the PDK exactly like the model I build,becouse this is the best arangement for mastering the electronic components that irradiate capacitance, I have tried diferent shapes that was impossible to control.

Once you get this correct shape , need to have a buried test to try the PDK, the tuning of the coil start with a 6N8 cap and you need to move slightly the coil up or down until you can pick the signal of the buried object, if there is no results you need to try other cap value until the receptor coil can catch the PHENOMENON, as you can see its hard to do...and unforyunatly you balance and tune the PDK for your area, if you go to search to other country with the PDK maybe not work, its like IMAGINE YOU GO WITH A METAL DETECTOR USING A FIXED GROUND BALANCE to a remote area where the ground conditions are completly diferent, the results are poor,YOU NEED TO TUNE AGAIN THE PDK.


As to the most asker question,WHAT IS THE STIMULATOR IN THE PDK-2.1, the right answer is the arangement of the electronic elements at the correct disposition that play as stimulator,and by ajusting the RX coil more far or more near the circuit this act as a stimulator for the coil,or FERRIT also can be used.

[Morgan]

I see you know a lot about LRL

I invite you to try your locators here in my field test

at your disposition I have all the LRL models you talk about and many others

however the best treasures I have found was using my PDKs

all mineoro DCH85 ,etc etc as very poor response or no response in my field test,other thaqt works is the old PD Alonso but as critical adjustment and drift a lot.

[GOLDEN LILLY]

Thanks for the prompt reply. I will follow your instructions carefully.
One last question, is the placement of the battery plays important role of the PDK?

Hello GOLDEN LILLY

Would you like to tell me the inductance of your coil, i want to calculate frequency range for Morgan pdk.

your crt tv is irrelevant for testing any lrl. Also battery spark is irrelevant, mobile phone also, any kind of remote transmitters also.

make silver loop target, with 1-2kg salt, and wait a month, if a weather is hot, you will have where to test your pdk.

Esteban cabrera grinok advice is to use big copper plate /as bigger/ you could find, expose it to hot sunlight several hours, and make short therm test but not from long distance. Maybe help....

For temperature stability use only silver-mica high quality capacitors, especially those playing role as resonant capacitors, also use them as decoupling capacitors. instead electrolytic capacitors use tantalum with very small leakage curents, and working voltage 4x bigger than working pdk voltgage. best stability you will get if you connect transistors thermally with each other.

Hello Morgan

From analysis of you words, if they are truth /i think you are talking a truth but not the whole truth/ i can do undestand that your pdk is capacitive long range locator. . About ''mastering the electronic components that irradiate capacitance,... '' and ''diferent shapes impossibile to control /capacitance/'' it is perfecly clear that you dont speak about active componets, like transistors or diodes or buzzer. it further mean that you dont speak about capacitors because you have made it and tried different shaps /you cant change the shape of factory capacitors/. only one stuff remain playing your game. inductance or inductor. but it is not ordinary inductor because that strange inductive componet irradiate capacitance. and that capacitance is not at all small value /part of pico farad/. so what is it......
from my electronic skills i know you are talking about coil-capacitor/s. it is only one componet which have twins attributes.

question is only one for me. how did you have coupled that strange coil-capacitor with main parallel LC tank coil. inductive or capacitive coupling or both in some proportions to maintain small oscillation due to target gold signal trigger.

if all i said is correct than your pdk live /work/ on the eadge of super sensitive magnetic receiver and super small output capacitive oscillator. jumping over the eadge and go back when he jumped.

maybe if you are good will, you would give some priceless valuable informations.

ps. i have a strong intuition that pdk operator is a part of passive receiver circuit. / / point of sensitivity is reached when a beep /oscillations/ is heard by touching the knob /capacitive coupling via operator finger/ and turning the sensitivity to its triangle mark /triangle mode LRLR /*INDUCTOR-CAPACITOR-OPERATOR**including self capacitance of pdk operator/.

ps. Morgan tell us about real test distance you have pass through a golden sieve of your pdk and how big were treasures /gold coins overjump for public release / /.

[Dubulumach]

Morgan , does it possible that your pdk work as a real long range locator , at kilometer or several km distances.

i think it is very possible. probability 0.98.

but you should understand what the ''hallo effect'' is? in very begining.

remember Esteban words, about real lrl hunters in brasil, how they did a job /found a gold/ from a half of mile, and maybe much bigger than half of mile. / /

I know Esteban Cabrera Grinok, had told a TRUTH.
Coul you help him ?

Hi Dubulumach, my coil inductance is 170 microhenry. This is from 40 turns, .30mm and 6 cm diameter.

[abdou2014]

170uH ( 2.2nf - 12nf ) = ( 260 khz - 111 khz ) . did you try to fall on the second or third harmony of 77.5 khz ( 155 khz - 232.5 khz ), or on a LW radio station ???

[Dubulumach]

Hi Morgan

have you tested this newest alonso pd with square aluminium loop.
tell me about real test results. do you have schematic and coil data for it.

This is said to be a static detector. Morgan knows it.

Thank you GOLDEN LILLY,

Do you have original Morgan PDK or self-made.

[GOLDEN LILLY]

Self made...and I am still experimenting its behaviour with different coils and tuning capacitors.

[Dubulumach]

Hello Morgan

I am very interesting in this new LRL by Alonso. Have you some technical details about coils and electronics.
Did he used his original passive reciver design or maybe new one with toroidal-wrapped coil. Currently i analyse Mineoro DCH210 which my friend Geo posted long time ago on this forum, and also Esteban Cabrera Grinok modification of DC2008, with new passive receiver, rf sniffer, big printed square loop copper coil and small ellipse loop balance coil. I am extremely interesting in those two designs because i think they are best lrls in the world.





ps. Morgan if you wish contact me at my private email. I think i found some very interesting behaviour of passive receiver ferrite core, which can drastic boost detection distance in your PDK-s. Also you should catch tiny mV signals with new active amplitude detector. I already drawn new passive receiver schematic but not made it and not tested on real field with gold and silver targets.

Morgan analyse this. It is the most informative schematic diagram i've found at this forum.


If you like to talk with me write at private email.

note: Estban's pasive receiver work with phase opposite signal at 180 el.degrees. To achieve no-signal mode, ferrite input LC tank circuit must be tuned to sense opposite phase of stimulus signal, so the net phase is zero or in other words ferrite output is hold balanse, was nulled. Halo effect from gold target or silver one, disturb mutual net phase, either from stimulus or ferrite LC tank or both. This avalanche disbalance act up amplitude rise at 2nd dc amplifier stage (rise voltage after diode rectification) and trigger audio beeper generator. Target detected.
