Hi FrancoItaly

To build your LRL, do I have to build according to the ''lrlfrancobase.pdf'' file ?
What should I do to strengthen your design?
Is your LRL an ion finder?
Does the LRL become stronger with the placement of the antenna?
Thank you

I post my original lrl, the antenna amplifier and pcb by Dream man, but for me it's better a single pcb for sensor stage. Before connecting antenna amplifier it is necessary to fine-tune the original version. I don't think this is an ion amplifier and the antenna is needed.

Yes it is, a further improvement that I am working on is to tune L1 / C10 on a harmonic of the quartz oscillator. To do this, you need to find different frequencies. I attach a new display stage that allows for better tuning.

hello franco https://github.com/dysonlin1/Air-2 The person who predicts the earthquake is actually doing business with your logic. I had the chance to examine this issue. The circuit controls the change of electric current in the air.

The shielding is not critical, the important thing is good electrical contact with the PCB ground and also the shielding of the handle.

As I have already stated previously, I am not giving help for this version, as out of the 3 lrls created only one works well, for the other two it does not.
