Lrl from Italy

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

I'm posting the material for building my lrl for a new forum member.

I assembled, Sense is better

Hello Mr. Arash, I managed to create the attached PCB and made it work, but I have difficulty in calibration. 5k pot, 20k and 500k, how should I adjust it, I would be grateful if you could help me, thank you in advance

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.

Thank you Mr. Franco
Which version works well?
What is a schematic?
Give me the schematic
Thank you for your love

Display stage (one or three LEDs) is the same as the 8 MHz version. The most sensitive version is 20 MHz, because the L/C circuit is tuned to a harmonic of the quartz oscillator. In the version with three LEDs, the stabilized power supply must be added which is shown in the 1 LED version.

Dear Franco Which sensor should I use for this?

The 20 Mhz sensor stage is essentially the same as the 8 Mhz version, there are some more adjustments but this makes setup easier, I think you can use the 20 Mhz instead of the 8 Mhz.

Hello Mr Franco.
I completed the assembly of the 8mhz crystal version, but I could not operate it. The measurements I took with the crystal are as follows. Can you help me please.

TR1=B:8,0v E:9,2v C:15,6v

TR2=B:0,2v E:0v C:5,8v

TR3=B:0,8v E:2v C:7v

TR4=B:2,4v E:1,8v C:7,6v

TR5=B:0v E:0v C:16v

My lrl is composed of the sensor stage + the display stage which also provides the stabilized 12V voltage, I attach the version with a LED which also includes the stabilizing part.
