OK, thanks.

Mineoro 2000 is a DCH85 detector with some mods.
At old DCHs there was a simple coil (one open turn) for the receiver, one coil (one open turn) for the rf sniffer (TDA7000) and one coil for coil stimulator. Also there was a one turn coil tuned with 150pf capacitor (as filter). You can search forum for everything about DCH and will understand everything about this detector.

Thank you Geo !!

Valuable informations !!

It seems to be some very tiny signal hunter at particular frequency. Very narrowband.


ps: about so called Mineoro Ionic chamber - for some of their detectors i think it work as Nano-Pulser (generator) with extremely law duty cycle. To catch such very sharp rising times (canbe in pico second domain) you need have some of 1GHz oscillograph bandwidth.

By the way this Mineoro "Ionic chamber" is very similar to Nikolai Tesla Spark-Gap controller and also with Edwin Gray tube (as main part of his Free Energy generator).


ps: I have not worked with any of Mineoro detectors.South american technology is unknown to me....

Hello brasilpb.
For the discrimination there is another one selector.
Can you tell me where is connected???

Thank you

[brasilpb]

in this version, that you postou, it must be the key to bind.

Sorry my mistake.
On the head there are 2 switches, one that changes the 3 coils and one yet. What it makes the other switch??

Regards

[brasilpb]

In my it only has a key, of the discrimination, and a key to test the stacks, power and off in the potentiometer.

[Geo]

Thank you

Hola brasilpb


informations about

1. Bobina Estimuladora
2. Bobina Receptor
3. Bobina connected to collector BC648 and other terminal to 22k resistor and make oscillator oscillating.

Dont talk ?? The reason ??

[brasilpb]

They do not have no linking in the circuit.

so, it's one of those RF related loops, which they often use in mineoro's.
Thanks for the answer brasilpb.

No, i"ll contact and inform you.

Hello friends,
What chip is this with a red circle ??
Does anyone in the forum know how to identify it ??
Or give some opinion or suggestion based on the scheme of this circuit.
Thanks to all who can help me.
.

[Geo]

If you interesting to construct it, you can make an oscillator at the same frequency (555. 4011 etc) and connect it to 4k7 resistance.

I am grateful for the attention.
I want to try to set up and see how this detector works.
I'll try some of these ICs, I hope it works.
But also I will be waiting for someone who knows that mysterious CI may appear.
Thank you my friend.

What is the function of the other 555?

[Geo]

There are 3x (555).
One is for audio (buzzer driver), one for battery test (i think) and the other is for coil stimulator.

[humhum]

Hi Geo , I think One is for audio (buzzer driver), other Two are for Stop of Stimulator Transmitter with (S) Button Controller ,(maybe will works only so like Passive Receiver).

[Geo]

Yes you have right.
With the existing values the 555 gives a pulse of 110sec and turn on the 2 transistors.
Nice observation

[Geo]

If i remember good... it is for pinpoint when the signal is very strong.
But i don't think that we will locate so strong signal with this device ...

Geo I write Wrong for works of 555, because Coil Stimulator works only if "S" button is pres.

Yes , Pinpointing olny with inside BFO circuit and with minimum sensitivity so like MD.

Thanks for the answer brasilpb.

Yes, You are Right Bill about Disc. My Two Version home made Mineoro works with same logic .

What is the receiver coil used in DCH85? Please show some pictures...
