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).
