Hi Behkli.
Please look your mesages.

This is a way to check if your long-distance device is able to detect the ions of metals. The movement of the battery negative to positive ions creates a RF wave, which is capable of being detected by a sensitive detector.

I dont think so!!!!.
Can you explain it more!!!
I have many lrls workable..... to test it but i hear it first time.

It could be very interesting, when I go back to Italy I'll definitely try, but as Geo says, it would be interesting to know other details.

Hi,
The IC5 can be CA3130?

[Geo]

Hi.
You must know that FG90 can't detect fresh gold so don't worry for it.
I am afraid that the missing IC is a 555. If you measure the voltage at pin1 and pin8 and you read a voltage of 9V then it is a 555. If Voltage between pin4 and pin8 is zero but between pin4 and pin7 is 9v then it is a single op.amp as 3130, 3140, 741, TL061 etc try what you have.
Please inform us about the voltage results.
FG80 don't have the U5 and the other IC right of the ion chamber
Also inform me about the IC type (number.... right of chamber), i think that is a 324....

Hi,
Thank you Geo.
Here is a picture of the ion chamber area, all their baseline IC are cleared as the photo shows.

I measured the voltage between the pins 1 and 8, I found 9.70 V.
