Lrl from Italy

[ali02]

Hi FrancoItaly
I made your LRL with SMD components, but I don't know how much to tune the potentiometer screws to adjust it? (I'm looking for gold)
But sometimes when I tune the potentiometers, and walk to the refrigerator door, the LED lights up and the speaker beeps, and when I walk away from the refrigerator, the lights go out and the speaker does not beep!
Also, when I walk to the place where the toilet well has been dug, the lights and speakers turn on!
Does this device detect a magnetic field or ions?
Best Regards

I don't know (and I don't know if there is) a frequency just for gold. It is normal for there to be many sources of disturbance in the home. Very little is known about the phenomenon, indeed according to "normal" science it does not exist. In my opinion, since it works with an antenna, it is an electromagnetic field.

I would like to warn those who intend to make the 20Mhz version of my lrl to wait because, while the first one works perfectly, the other two, which I did later, have problems with signal instability. I am making substantial changes and think I have solved the problem. I will post the changes as soon as possible.

Good luck mister franco
waiting for your new lrl

Good evening Franco! Did you solve the problem with signal instability?

Not yet, but I understand that part of the problem is that on + 12V there is a very large signal at 20Mhz. With the 8Mhz lrl there were not all these problems.
