mineoro fg/90

[abdou2014]

Thanks , i need these values

[abdou2014]

Does the frequency of the oscillator and the coil increase or decrease near the phenomenon?
or there is a change in the amplitude ?

[abdou2014]

I have new after several tests and this time with the original mineoro oscillator

I hope to have help and answers from members who have knowledge of this receiver

there are two different results on two different frequency ranges

for LF frequencies, the reaction distance of a 1.5 v spark is 80 cm, and it also reacts to non-ferrous metals, a piece of aluminum 30x30cm from 35cm

for VLF frequencies, it reacts to a 1.5v spark at a distance of 3 meters, and it does not react to non-ferrous metals

please, what is the favorable result to detect the phenomenon, when it detects non-ferrous metals and the spark or when it only detects the spark at a great distance ???

I don't know the answer but i can tell you the follow.
1. Battery spark don't mean anything about the ability of a lrl.
2. Battery spark sheems that a lrl work better or worst if the lrl has n't differences at frequency or at working principle.

I believe it is clear

Preamplifiers of tape recorders have filters so to work according to the NAB curve.
We need a flat curve.

The mineoro LRL receivers, like the two box detectors, are super regenerative receivers, and the frequency response is not flat. If the input oscillating LC circuit is tuned to 40khz for example, it will have its maximum sensitivity for frequency between 35 to 45khz. Pre-amps for tape deck, they are well-designed circuits with high gain and low noise, but they have a wide passband, reproducing from a few hz to about 20khz, and this is not good because there would be a lot of interference from the electrical network and its harmonics . The phenomenon apparently occupies a large spectrum of frequencies, and the secret is to choose an interference-free frequency, and design a sensitive receiver for that band with a narrow passband. If the receiver has a flat response, it will be immune to a lot of interference, being forced to reduce the circuit gain to not give false signals.

thank you geo, I just received a faulty fg90 from a friend , i will try to fix it

I keep asking myself... fix what? why it does not detect objects or does not turn on?

[folharin]

try to reverse engineer it until you get to the programmable ci..and try to measure the frequencies of each stage

I don't understand your position..ma your opinion the frequency doesn't matter then?

I don't know if it's normal, if I move it a bit faster it beeps ???

No, this is not normal! And when you raise it to the sky, does it also make a sound?

[abdou2014]

yes my friend

It's not scary! Need to make less amplification! Many, including myself, think that the more amplification, the better, this is a mistake. The higher the gain, the more extra interference.

Thank you

my friend geo!!!
I wonder why so many mysteries?we are all old group participants.

there is nothing left to hide one member from the other....tell the way to old members who are in this group from the beginning!!I've been in the group for twenty years

Hi.
Really i don't understand where is the mystery!!!!
So many years here it is logic that i tired, i can't be more active.
From the other way English is n't my language so i need much time to write a message and check it for wrongs.
Also i don't know everything on lrls, i am not able to explain everything is happening with them.

Anyway.... Regards

Many times when you work with depth sensitivity at high you have this phenomenon. Try it with depth sensitivity at Normal

[abdou2014]

Thank you dear friend, I thought it was because of the humidity or the power lines, I was surrounded by trees and 600 meters from the power lines

Here Frequencies is important and it is for carrier of Phenomenon signal , from to distance , and this carrier frequency some time is different for all Country.
PD and LRL not need big gain or sensitivity , need some info details and very long time for real calibration , all reality is this for build of a real Receiver .
We forum have all infos with details , only need time for read and experiment .
No secrets left ....

[Geo]

Most info are in this forum but there are hidden very well!!.
Every interested must read very carefully all the threads and maybe to learn the secrets.

[humhum]

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...


IR leds is a none working mambo jumbo tech which works very good as a bate!
