mineoro special serie 2000

[Geo]

Mineoro (Alonso) plays often with frequencies.
Maybe they are looking for frequencies where the noise background is lower....

[Geo]

Nobody not interesting about this strange audio stage;

[WM6]

Only vacuum tube is missing in those audio.

[Geo]

Hahaha.... NO.
Mineoro here try to cutch very "thin" signals.....
It is another "philosophy"....

[Geo]

Any news from brasilpb???
Did you made mod at oscillator???

[brasilpb]

I spoke to the man who sent me the circuit. And he told me, there were two coil in the oscillator circuit. The other coil terminal I connected the collector and the other for the 22k resistor and the oscillator oscillated.

[Geo]

Thank you.
Do you know the frequency of this oscillator????
I try to understand the usefully of the 130Khz oscillator.

Regards

[brasilpb]

Yes the oscillator, also functions in 130khz. The circuit is type one bfo, metals of close it detect, and the stage of fm functions in 120MHZ.

[Geo]

Ohh yes, very good... a classic Alonso's schematic.
So coil stimulator(555) is for the Rf sniffer!!!

Now all are clean!!!

Thank you.

[Geo]

btw... brasilpb do you know how old is this detector (series 2000)???
Also does the owner found anything with it???

Regards

[brasilpb]

Yes the old owner of the device said that already he had found some things with it.

Brasilpb Hi

can you give informations about

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

Best regards from Russia !!

Geo Hi !!

Geo tell us how NE555 at 1500 Hz can be a RF siniffer ??

What kind of stumulation make NE555 at 1.5KHz ??

Maybe stimulate golden and silver targets make emmiting RF pulses using piezoelectric transducer ??

Hi.
I lnow the model but i don't know how old is it??? maybe near to 1990....
