mineoro fg/90

Yes, that's right, Master Geo, even all of them are clearly written,
The important thing is to detect it and apply it.
Actually, the logic is very simple (except for the setting), it will be enough for the device
builders to read their comments and understand them.
Grand Master Esteban used to say that Remote sensing devices are made up of ordinary
schematics.

Is mineoro electrostatic receiver or electromagnetic receiver?

Hi Brain
Mineoro has two receivers actually. The first consist of the two loops. It takes as an input the frequency that is determined by the free LC at the front. It is something close to 14MHz. It gives a beeping signal when this signal drops. So it some kind detects the null or a disturbance at this MHz signal frequency. (This MHz signal is also modulated by the input oscillator at KHz)

The second receiver is of an electrostatic nature. In fact there are a lot of circuits in the internet, utilizing a jfet as for to receive electrostatic charges. It is exactly this. It gives a beeping signal when this field nulls. This is when the sensor (brass tip) of the machine sees the target in a straight line.

Hope it helps

The thing I see is franco lrl electromagnetic mineorro, it's electrostatic. Actually, all the work changes according to the use of the first transistor. The IR used in the mineoro works as an electromagnetic field determinant. I hope I'm not wrong.

Franco's receiver doesn't look like an electrostatic receiver. It is more an electric field meter. It creates an oscillation at the input and device traces any possible offset of the waveform. The number of transistors determines if it will catch a negative or a positive offset. In Franco's case it detects the positive side. And so the increase in signal when the antenna looks at the negative source target...

I confirmed that my friend's FG90 has a problem, even if I make it move towards the sky, and even by decreasing the sensitivity to 10, the slightest movement gives beeps

The device may have mechanical problems. Pay attention to the resistance of the case to mechanical movements when holding the device by the handle of the holder. Or turn on the device, place it on a flat surface, hold the body with one hand and, without fanaticism, press left and right on the handle by which you hold the device. This is one of the most common reasons.

I think my lrl is a passive electromagnetic device, the internal oscillator only serves to create a reference signal for the mixer, while the phenomenon is in the FM range, the L / C values prove it.

I did the handle test and there is no beep , only with full movement of the device , thank you for your help

Hi Abdou.
Its difficult to repair the lrl from distance, this must be maken by you.
FG90 has 3 detectors. You must isolate every time the two detectors and let only one to work so to understand where is the problem.
First detector is the receiver on the board FG38679B.
2nd is the ion chamber and 3th is the magnetic receiver at right side of chamber.
For begining desolder the red wire of ion chamber and take out the IC of the magnetic receiver.
Move it to see if you have random beeps.....

[abdou2014]

Thank you very much Dear friend , I don't know where to start, I'll take your advice ,

[abdou2014]

- I cut the red wire of the ionic chamber and I removed the IC from the magnetic receiver

- when the switch (deep sensitivity) is in the ( normal ) position , no beep when the device is

in movement

- when the switch (deep sensitivity) is in the ( high ) position , beep in any movement even

with low sensitivity

[abdou2014]

I put the magnetic IC in its place, the device is always stable and silent in mouvement

and that with (deep sensitivity) in the ( normal ) position ,

this deduces that the parasite came from the ionic chamber ?

[abdou2014]

I also want to know is it still able to detect the phenomenon without the ionic chamber ?

how reliable and how far can it detect a treasure without the ionic camber ?

Thank you !

[abdou2014]

I tried them yesterday, it was windy and it gave false beeps , I want to know if this is normal?
