Mineoro 2-Box -- 492 feet range?

[Esteban]

Esteban, I think the IR work in conjunction with the IF wide bandwidth of the coil as a receving enhancer. I think I know what he had in mind. I still think that with another winding configuration for the coil there could be an improvement. I have several oscilator circuits at disposal which I could include the timer and try using another winding configuration. Do you allow me to do that if I have time?

Also I think I may know where this patent is.

Regards.

And this unbalances the equilibrium.

[Esteban]

Hi Esteban,

Are you saying that this device will not work as a medium range locator if the IR circuit is not included?

Can work, but IR helps a lot.

Be patient. Morgan has only posted 2 of the 6 circuits so far. Perhaps, after that, we can get a translation.
Anyway, all the resistor values are missing.

OK, Man, good work, very nice. our eyes is on your abilities to translate it to a usable and brief form. now I'm somehow confused that surely some others are so.
again especial thanks for Morgan, Esteban and thanks for other diligents; Qiaozhi, Max. god bless you all for your efforts.
If all details be reflected exact right and be combined with your efforts will become a great unforgettable memento from makers.

A lot of circuits,big confusion...

Before was 1,2,3,now its 4,5,6.

Resistors

Hi Morgan,

Thanks - so that's what it means.
R13 = 470 ohms, 5% tolerance.

Now - with circuit #2:
R2 = 82k, R3 = 27k, R5 = 12k, etc.
But - R1 has 5 colours (not including gold, which is the tolerance) and R4 only has 2 colours. Please can you recheck these? Either 3 or 4 bands + tolerance is normal.

Important note:
R1(circuit2)
R5(circuit3)
R1(circuit6)
are the same(red,brown,red,black,white,golden)
You can see one of them in the center of this photo.

Hello Fred,i already put some corrections about resistors in PCB 2,3,6.
Unfortunly i dont have permition to open the antenna,but i think if we have some genius here,we can build and put to work this device.
I saw carefuly the Antenna and didnt find any Infra Red,maybe its inside...

[Fred]

I hope esteban can help about the "antenna".

Here is the PCB2 reverse-engineered.It may contain errors of course.
Regards,
Fred.

max, you certified me?

circuit 1 regulator
circuit 2 modulation and filters?
circuit 3 amplifier?
circuit 4 sound tac tac
circuit 5 preamplifier?
circuit 6 oscilator

Hi Morgan,

Please could you make an in-circuit resistance measurement of this resistor? It's probably a 2.12K resistor. This particular colour coding is unknown to me.

Hi Morgan,

Please could you also check the connectivity of the wiring to the antenna, i.e. what is the resistance measurement between the different wires?

I have completed the reverse-engineering of circuit #5, but some visitors are coming to my home today. Hopefully I can post the result in a day or two. So far I cannot see any evidence of a 7kV generator. It looks more like a receiver to me.

Morgan - one more request -> please could you also do a connectivity test on the ferrite cores. i.e. what are the resistances between the wires that go to the coils?

And this unbalances the equilibrium.

What equilibrium?
