Hi.
All coins was buried without salt.
Now i sent the PDK2 back to the owner. I have the same results with mine....
Now i work on a new lrl that will be more sensitive from PDK2... and will have the ability to replace the PDK or to put it inside a Mineoro and to make it very strong. I believe to have good results.

Regards

did you check the PDK-2 frequency in your oscilloscope ?
i´m interested to know,i think is aroud 125-150 KHz ?

regards

building one simple EMF locator,you will have one LRL better than mineoro ,and low cost...

the answer about the PDK-2,i keep for me the modifications,but your friend Geo can clarify about the schematic,he build one PDK some years ago. Is 10 times more powerfull than the mineoro.

I checked it with a generator and itis tuned at 78.8 Khz.
Another member that has one pdk measured it and these is tuned at 81 Khz.
Mineoro DC2008 is tuned at 133.6Khz.

Regards

Ok, and my PDK-2 is tuned 77.7 KHz,this is normal.

However ,in other PDK´s is 130-150 KHz, the frequencies for precious metal are from 62 KHz to 150 KHz,in between this frequencies the locator behavior is more or less selective to gold.
For example,more high,more selective.

If frequency is upper 150Khz then it is more sensitive to aluminium

Hi.
Now i have a FG80 for modification.
What i saw.... it's the same locator with the DC2008. The only difference is the IR led that the FG80 has in the front panel but i don't think if it works.
All the other are the same with 2008.
Also it has different frequency...

Regards

about the MINEORO
 

Geo,here is something interesting :

MINEORO model PDC 210 super -- can locate 1,5v battery spark,if you touch the ionic chamber it emit beeps,not locate fresh gold.


model DC2006 -- can locate the 1,5V spark,locate your hand if pass in front of the Ion. chamber,not locate fresh gold.

model DC2008 -- can locate the 1,5V spark,not locate the hand in front,locate fresh gold in front of the large antenna.

model DCH85 -- not locate the 1,5V spark,locate the hand in front of antenna,not locate fresh gold.


I cant say that MINEORO is a fraud,they are LRL´s that need the special weather conditions to pick a gold target.
I have a few objects found with my DC2008,but was impossible to pinpoint them,need the MD.
Using and testing the DC2006 i found some weeks ago one old silver plated fork,distance 2 m,deep 20 cm,humidity 10%,it give me one area of 1 square meter,pinpoint using MD.
Sure it was the factor low humidity and advanced age of the fork(200 years underground) who make the DC2006 react to the object,i note also that it can pick the target only in the limit of sensitivity,otherwise not possible.

It was my first object found with MINEORO DC2006 ,i bought this LRL in 2006...

Mineoro is a real LRL but it is a very BAD lrl.
I believe that with a good modification on the receiver it will be a good lrl. The fact that it can locate buried objects from distance it means that has a receiver who can locate the "gold signal", a very "strange" signal. Now about the bad distance..... it is from low sensitivity.

Thank for your info.
Regards

one second ,
Mr.Morgan , you were saying that PDK is working with VHF reflections,
but above letters, you are saying that it work s between 130-150khz
not Mhz , how can one antenna be tuned for two different EMF regions?
I am confused sir?
If I understood your words wrong, forgive me..

Hello my friend George!
* really would like to know if the chamber indeed helping response.
Please let me know ...
THANKS!
;)

Hi kosta.
I am not sure yet, i will inform you when i"ll be sure

Regards:)

I.m even more confused than you about that.

Maybe the VHF that was working here with 175.25 MHz to 210.25 MHz this waves reinforced the electromagnetic field around the buried gold. Other theory is the VHF is the TRANSMITTER antenna and the PDK the RECEIVER and the buried object in between is signal relection.

The real fact is at 24-04-2012 the VHF transmittion stop in my country,and in the they after i note the PDK is not the same losing 50% of the LRL power. In Greece one friend reports the same problem when they finish VHF...

Morgan
where you from? where do you live, I wonder the VHF signal losen area .

remove the epoxy resine
 

hello GEO.

how I can remove the epoxy from a circuit.

My circuit is part of a Mineoro DC2008.

You have Mineoro DC2008 scheme?.

DC2008 good resolution images
 

Hi everybody, i need a good resolution of lmages of dc2008 from front and back side of it. If available then please post it as well as drawn schematics with values if any. Lets try to clone mineoro's pride whether functional or not. The pictures already posted in this thread is not sufficient to warrant cloning, it has no pictures on the back of the back receiver. I think its time for Morgan to post the good resolution images here.

Regads...

Hi. somewhere in forum i put the receiver of DC2008. I have not all the value of components because it was a hard work. Had to be desold all the components. Why you need to remove the epoxy????. A good way is to warms and cools it many times.

i have this i hope it help you

how you will schedule the memory atmel?

Thanks GEO,
Why you need to remove the epoxy????. Mineoro "NO POWER ON"

I've fixed some problems that had mineoro DC2008.

1. - Potentiometer not connected correctly.
2. - battery Holders broken.
3. - Ground wire with false contacts.

Mineoro POWER ON
Detects a spark 1.5V to 60cm.

Can anyone tell me if the operation is normal DC2008. that can detect a spark 1.5 to 60cm.

This diagram does not correspond to mineoro DC2008.

The DC2008 does not have the ATMEL CHIP

the problem is,i lost the images...

have this one only
