Hi Geo

Yes Geo has a right. No way to reduce the background noise because its etheric noise due to etheric wind.

But we can improve SNR ratio of the receiver circuit and catch the tiny signals from the phenomenon.

1. Use special ferrite rods for a wanted frequency range
2. Don't use high values resistive loads
3. Shrink the receiver's bandwidth to get it very narrow, improving Q factor and free signal from the wideband noise whick rise quadratically.
4. Use minimum number of componnets in the receiver's circuit because every new one bring own self noise to the circuit.

Criogenically techniques we don't get into the account.

Regards

Hello, Dubulumach!
If the Q is increased, its square oscillation will also increase ..a very high Q and with precise tuning at a frequency (Ψ) will bring a gain above 5v~ ..but again this can be corrected..etc. .
The point is that you have worked to find a proper ferrite two piece receiver and you have gathered the high Q value of the effect can you give us details about the double ferrite?winding etc.
we have coils that catch part of the Φαινόμενο the signal but no a good two piece ferrite coil..

nice work.. as I know you using draw by splan .. you forgot chamber antenna

[aft_72005]

other thing .. is really working as long range ?

[Dubulumach]

Any lrl need Tx stage (stimulator) precisely tuned with the receiver to work.
Schametic i have gave is a dynamic frontend receiver much better than primitive schematic of Alonso PD or any other schematic at forum. Transistors you need low noise type and diodes are germanium type. Ferrite coils should be tuned for the desired freq.range. Experiments are the judges of theoris so if you need it you will try it.

hello dubulumach
I wonder if there is a component list for message 229.
If there is no special situation, I can also wait by e-mail.

Hi Dubulumach

Please send the parts list to my email.
Thank you

At first glance, the circuit is simple, but it is very capricious to set up. Even with high-quality parts, it may stop working due to changes in temperature or humidity. It?s interesting how the receiving path of the FG-90 behaves. If you have experience, please share your observations.

Ferrite core of magnetic receiver is IP6 / 2000 (potcore).
I have n't details of the other ferrites back of the ion chamber.
FG90 has n't IR receiver

I attach the picture of my fg 90 and IR reciver

Hi dear Dubulumach
In my fg90 , to pin freq i have 864 HZ with 4.7 volt but this frequncy
It passes from R7 resistance to osc pin .
How many ohms is R7? 1M ohm????
In my IR transmiter we have 153 HZ with 7 volt , but my receiver IR is defective ، What type of IR receiver can i replace?
My device is faulty.

[ishtar hunter]

For electric field... stylus ant.
I can't test electric field pcb inside the lab, only outside.

Hi dear GEO.

What is the internal structure of the ion chamber?
Do we can use stylus ant Instead ion chamber?

Thanks for sharing the photos, very interesting the circuit of the FG90 we have never seen the inside of the FG90 before.. I see an optical detection system and a magnetic detection system.. I think the ion chamber has been replaced with an IR circuit I think it does the same job better I guess..the magnetic circuit is in many models the same as in this one..we have seen many times before the same things 2 in 1 systems from the manufacturer similar. the IR receiver circuit is interesting if you wish you can share it with me and tell you some details about the systems handling.

My device is defective and I do not have access to the manufacturer of the device. I just want to repair and calibrate my device. I would be grateful if anyone could help me.
The regulator ic was defective, and this problem was caused by the device's PCB, which had a short circuit. The 2646 transistor was defective and the LED inside the ion chamber is also defective. I did not open the inside of the ion chamber, but if I have to, I should open it. I don't know what kind of LED is inside the ion chamber. I have a problem with the frequency of the ion chamber. In practice, the ion chamber does not work. There is a frequency of 774 Hz at the head of R7, but then the resistance of this frequency is destroyed by the ohm of R7(1m ohm). I think the ion chamber frequency should not be 774 Hz. In the ORG pin, when the ion chamber is not connected, there is a voltage of 14.9 volts, but when I connect the ion chamber, this voltage decreases drastically.

Hello

Since there is no short circuit protection, all LED types of your device are burned out. In addition, it affected the magnetic receiver. First, make the magnetic receiver card independent. Remove the sensor IR RX leads and measure at the diode level (+-1800 will be seen). Then replace it with a new 555 one.

Thank's dear yusuf , Do you are from turkiş?
I already replaced IC 555 . But what type of receiver should I replace? 700 or 1000 nm? The infrared frequency of the transmitter of my device is 153 HZ with 7 volt. My ion chamber freq is 864 HZ .
