The point of the situation

[FrancoItaly]

Hi Geo

I tested the 2 working lrls and the last with the 2pF capacitor with a transmitter for remote control (about 430 Mhz) and this gives a strong signal at about 15 cm for the 3 lrls and with the stylus antenna 20 cm elongated. This test doesn't work with remote control for car but with remote-controlled electrical outlets.

Doing well geo. all the best to you.

Hi Geo

I post here the last version of my lrl, it works well as the others, but it oscillates with the help of a small capacitor connected between collector of TR3 and base of TR2, the right value is 0.5pF (also 2 capacitors 1pF connected in series). With 2pF as your circuit the lrl dosn't cacht the phenomenon, I have tried this value. The DC out is 3V, if it is less You must increase C8 and vice versa. R11, R12, C13 and C14 are a low pass filter to remove any residue of high frequency signal. Also this lrl senses the silver coins at about 2 meters.
to increase the sensitivity You must lengthen the antenna, by this way it's possible a sort of pinpoint.

When you say it works as well as the others what does that mean?

Are the silver coins buried in the ground or setting on the surface of ground?

Hi Funfinder
The silver coins are buried about 20 cm under ground 1 year ago .

Hi goldfinder
Sorry You are Gold non Fun...finder .

Hi Franco


the coins are buried with some salt to make the PHENOMENON more active ,or without ?

Hi Franco.
Thank you for the file.
What i see at NI stimulator is that this don't oscillate good. It oscillates near to 2.2Mhz modulated at 45Khz and after some seconds it oscillates only at 45Khz and again the same ... and so on...
How your oscillator works??

Hi FrancoItaly!
Please let me know what is the value of capacitor C3?
whether 22pF?
Thanks in advance for the answer!

Hi All

The coins are buried without salt or no other substance, C3 is 22nF.
In my circuit the DC out is very stable, but this values depend on the gain of the transistors. The NI simulator does not allow to change the "beta" of transistor and this may explain the instability. I suggest you build the circuit with 0.5 pF and try different values for C6 and C8 to a proper DC out. If you don't have success try 1pF. The purpose is to have the max gain of the circuit and with a greater capacitor in the positive reaction we will be forced to decrease the gain by changing C6 and C8.

i no see to brodhy morgan build or gave opinions, on this lrl

yes,correct,i have my LRLs,PDKs,remember ?

[detectoman]

then morgans, your think what yours lrl are the best non plus ultra? and then no need most prototipes propossal?

until now i dont know better LRLs...
