Lrl from Italy

What here on the forum we call "phenomenon" is not recognized by "official" science and I know very little about it. I can broadly explain how my lrl works: a signal of 8Mhz (I have successfully tested in the 2.5 - 10Mhz range) is amplified many times by TR2 / TR3 / TR4. At the base of TR2 the signal of the internal oscillator (8Mhz) is mixed with that coming from the antenna and on the emitter of TR5 there is a DC voltage which increases in amplitude in the presence of the "phenomenon". As Esteban said, without a doubt the most authoritative expert in this field, even an FM receiver that is not tuned to a channel functions as an lrl. Also my lrl is not tuned to a particular frequency, in fact we can use for L1 two or three turns and for C10 10pF or 22pF or 33pF or nothing (the parasitic capacitance between base and emitter of TR2 is always present).

Franco used the aluminum plate on the antenna?

Hello Franco Circuit should have two parts or one part

[zixelll]

Why in Iran some friends have been happy with this device and others have not yet made any conclusions. Are there any changes to this circuit?

Sensor stage and display stage, but one PCB (Dream_Man)

This is for me a real mistery. Perhaps an imperfect calibration or a not good target for tests.

what are the errors in our pcb, what are the particular thing in dream-man design ???

is this PCB correct, (mustefa modified ) ???

I have not tried this PCB. My PCB is Ok, perhaps not professional but it's almost impossible that self oscillates.

Hello my friend, did you build this circuit?

I said that I not tried this PCB, but the schemas is correct.

[abdou2014]

what should it be far away and from what, so that we do not have a self oscillation ???

As I said many times, the lrl has a very high gain and for me it's better to use a single PCB
for sensor stage (better is it's double face). If the gain is poor the lrl cannot reveal the phenomenon also is all parameters are OK.

[abdou2014]

the fact that I have the sky effect, I do not think I have a low gain, I will put a piece of aluminum connect to the ground between the sensor and the display ,

If you have not only the sky effect but also the compass effect the gain is good, not necessary other changes.

[abdou2014]

I also have the effect of the compass, the led lights up towards the south .

You can give a full explanation of the calibration, thanks so much

Here the helps

Thanks c10 should also be set to l1?

in my lrl works well in the range:
for L1 2 or 3 turns
for C10 from nothing (there is always the parasitic capacitance base/emitter of TR2) to 33pf
(that's 10 or 15 or 22 or 33pF)

Hello
Dear All.
In 8Mhz version, i can't find D1 and D2 (1N414P). Please introduce an alternative.
Thanks.

[abdou2014]

1N4148 not 1N414P

[HaFar2010]

Thanks my friend.
