PDK inside
Hi all
Last month via a friend i have my hands a PDK 2.1 from Morgan. The machine fell from the hands of my friend in a ravine and destroyed. After this my friend gave to me PDK if I can do repairs. More out of curiosity and less for repairs, I decided to open foam and see what I can do. I can not post here contains what and how exactly it worked, because is commercial project by Morgan. But i can publish some photo's inside machine for view all members this amateur work I published this thread because, as others don't like them publish personal schematics or circuits without their approval, so i don't like use my modifications that I've done without my approval. Sometimes a small courtesy is enough. But if approval is not given or there is no courtesy, but only ironically etc, i forced to use the same methd Yes PDK use many modifications by me So this is enough for me (use my mods for commercial project without my remission or a small note from my mods) start again with this LRL and draw new modifications, because PDK with standards schematic-circuit is a circuit without something more interest for me. What i can do. It will maintain the basic design without extra something in the circuit. Basically i need change the final drive piezo stage and sensitivity the first preamp stage with small tips for reject more false signals. In the basic circuit i would only add one extra mod for the appliance can be adjusted by me in the search-area without protection calibration very-very easy. I feel this way everything can work properly. You know the big problem is calibration. If i calibrate and protect all circuits or coils my lab, maybe don't work this LRL other search-area. Please you remember some LRL need extreme calibration for fine work. It's so difficult use this method, because, with ONLY difference temperature sometimes LRL can untune. Honestly, I want to mention something. There was no case to deal with this PDK or i try to copy the circuit. But here I have a different situation. Supposedly there is a forum for amateurs, but only see attempts to replicate and exploitation. And the funny thing is that some want to hide and posing for amateur and they helps others, in practice many members has double face At least here , I feel good about myself, why i work again with something i studied enough time before and nobody can tell me that I make a copy. I will publish here the progress of the whole structure in my free time Ways of presenting work correctly my personal LRL or not, I think i have something, that no one can have doubts regards

For aft_7205, vali, nelson.... etc
I don't like publish false infos, of course I respect the hard work by morgan etc (amateur or not no matter for me) and don't allow me to give you, more information without permission. The photo's shows the "General" inside the device. If you need more infos, you can ask morgan. I just want to correct a mistake. Τhis is last version PDK2.2 Personally, i will deal only with my mods,i will improve and presentations. I Repeat again. If my personal LRL (build my free time) work or not, I have found a method, with this method not there by any doubt. regards

PDK-2
Quote:
Thanks Andreas,to not desmantle completly this PDK-2,yes is the old model 2, not the 2.1 or 2.2 this last models are more powerful. I know from the picture ,this PDK-2 was sold long time ago to a person from Atens,name Charris Dimitris G., this person ask me a few questions about if was possible to change the FINE TUNING linear Potentiometer for a MULTITURN and this make the calibration more easy,i said NO,if he change the Pot. this PDK cant locate more targets,i made many tests using Multiturns... BTW: I have a few emails from Charris telling about his finds with this PDK-2, that i ask him photos but never get this photos... I dont understand why he not contact me for repair the PDK-2,and i can easily upgrade this one for the 2.1, as i told,the model PDK-2 is very dependent of VHF electromagnetic waves ... keep your mind just on repair and not say too much about this AMATEUR LRL,if you respect others,others will respect you,not break the line  Regards

and here is a very positive claim of objects he found in the field,if there is someone want and dont believe,i can post a photo of this emails here the PDK-2 report of Charris data 26-04-2012 : the PDK2 works very good...I found silver coin not so old and an old Necklace which they use before many years to put there wishes...off cource i use as well my detector. The think that the last 6 months i work a very big project (maybe one of the biggest in Greece) is a truly story after the war more than 10 bullet boxes. The problem that i have is that i bought also the PD (with ferrite) you remember the scematic of Qiaozhi but realy i dont trust it at all, the only good think is i can detect gold more than 1,5 km (and all the scrup) but i cant go near to the target . I need your help If you event anyLRL that i can use it for a big distance. After 15 days ill travel to Germany to see KS700, i know so many works here in my country and im trying to have the best detectors to avoid any mistakes. Anyway any help from you will be very helpfull. Regards Charris

Hi Master , before you said that PDK use St. Oscillator + Toroid where is this two parts in this Picture.

PDK greek forgeries
ok, i know also there is one person who claim to have copy completly one PDK-2.1 and start massive sales in Greece, good luck ,im not interested at all,i quit from this project some time ago.
What i not like is some PSAXTIRIA forum member Goldmaniac tell that is waithing for a PDK-2.4 from me, at the same time that he is building this clone,what is that??? this is big LIES, PDK-2.4 NOT EXIST, now starts LRL greek FORGERIES ??? EVEN IF THEY CLONE A PDK, IT WILL NEVER WORKS LIKE THE ORIGINAL

Morgan
Why you said that? If PDK wires are moved, it means that your circuit is very unstable and has frequency drifts. We all know that this circuit has basic electronics, and also work on very low frequency spectrum, so moving some cables must not affect performance has you point out and if you have to do some tunning, it´s just easy to have a field test to work on and go for try and errors until you get the signal. Today we also know that frequency is not to critical. About problems with VHF, for me is just a problem with harmonics, so is just a matter of changing frequencies a little. Regards Nelson Quote:

Adreas,how you go to TUNE this PDK ???
What do you say. I can do or not this is a question? ..this is the circuit of a PDK-2.2 ,is diferent : (post #13 photo) My drawing and PCB two years ago. All members can see the same philoshophy drawing PCB and my "signature" design. My PCB as same "your" PCB or not? Also this is a question
