Lrl from Italy

[Kamal]

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.

Hello Mr Franco
How are you, i hope you are well.
Lrl works with N/S magnetic..ok.
Does it also work through sky effect?
What does sky effect mean for you.
Mixture of locally propageted /available frequencies on the Air?
İf so, can we say that...if our Total antenna reciever is tuned to any of local frequencies ,we will have sky effect Upon elebvating tip of antenna up. İf there is no match to a frequency ,we wont have sky effect..
Can we think in this way , to Check if our lrl is tuned correctly or not?
İn a away ,Franco lrl is a passive reciever like pdk4..pdk is working on frequency matching condition
So, what about Franco?
Francolrl seems like wide band reciver.. residue of any frequency available or mix of them ,will cause increase in receipt Signal. Think like passengers on carrier wagoon..
Just trying to have brain storming of occurance of unknown phenomon

The phenomenon is very complex, as far as my lrl is concerned the sky effect and the compass effect are eliminated by decreasing the gain. The TR2 mixer has an output, even in the absence of a signal (this is intentional). Any signal that passes the L1/C10 filter modifies the mixer output, so even a signal out of range but very strong (as you said correctly).

you can try this antenna amplifier suggested by a forum member, the sensitivity increases slightly, at least in my tests. However, the antenna is the same for the 8Mhz and 20Mhz versions.
