Thanks for your guide
HiOriginally posted by FrancoItaly View PostYou're right, the reason is that I did not point to the LM358's power legs, in the Dream.man scheme they are shown correctly. The output of the sensor stage is in the 4-6V range and the quartz oscillator oscillates equally without the second capacitor thanks to the parasitic capacities and it seems to me that when I posted the project I said to add the condenser if the oscillator had not It worked. However I built 10 copies of this lrl and the quartz has always oscillated.
Please accept my apologize for asking many questions.I want to know what kind of signal must be on the antenna what frequency and amplitude.

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).Originally posted by maziio View PostHi
