MINEORO 2008 MODS.

thanks geo for put schematic of dc 2008 . but is not complete , my mean is part list !!

can you share part list ?

[Geo]

Sorry but i can't post part list.
I received many mails that ask me to share the part list.
Because i don't like to answer to all the same, i write it here.
No part list.
I attached the schematic of receiver so the members that understands electronics to see what is happening.
I believe that every one can experiment on this schematic by calculated the components....

Regards

[iam_7up_gamer]

yes geo you say right part list can calculation . just take time

you'r static detector is sensitivity to especial metal ??

[Geo]

My detector is not static....

[Mike(Mont)]

I believe it could be done at a different system.
Here transmitter and receiver have the first stage common, so the more high power at oscillator the lower sensitivity at receiver. All the story is to find the balance point for better results(at normal terrain).

Yes, I realize my system is different and it's very easy to change the power levels. Don't know what type of soil you have, I think I read somewhere the soil in Greece is difficult. We have the bentonite clay around here. Clay can hold water and make for areas of high conductivity. The voltage can get trapped in the the soil.

if is not static so is electric , is right geo ??

micro voltmeter or mili voltmeter ???

Yes, you remember right.
The soil here has big amounts of iron oxides and decrease the phenomenon.
I saw very big difference at phenomenon from City to City.
At places with big amounts of iron oxides when increase the transmitting power then we have erratic signals.

hi
I know geo interesting to combine mfd with radio like the andy flind
I guess the second circuit is rf


best regards

Hi.
Please don't write with capital letters, is very tiring.
This schematic has nothing to do with FG79. It is for FG80, FG90 and DC2008.
Frequency depends of the model. Fg90 is near to 34Khz, FG80 80...85 and DC2008 near to 100....105Khz. This time i don't remember exactly

i am sorry my mean was fg90 about tuning frequency35-40khz

Maybe electric field detector, maybe UV receiver maybe both... i did n't decide yet.
Experiments will show...

[Mike(Mont)]

Conductive ground absorbs the signal.

[Geo]

I agree, this is the reason that iron oxides at soil decrease the signal.
Also a big amount of iron near to target destroy the phenomenon...
Near to my City we are not Lucky

Yes , Absolutely right.

Here there is the schematic of the receiver.
The 1st Transistor works as oscillator

First Tr. is self RF OSC ,also time is very sensitive Preamplifier for Static and Electromagnetic potentials .
