I'm sorry but I do not have the pcb of CD4046 version, I modified the 8Mhz version to try to get a sort of discrimination by comparing the phase and amplitude variations. I recommend making the 8Mhz version because it is simpler to accomplish and has the same performance. I also recommend the stylus antenna with respect to the coil antenna possibly connecting 3 stylus antennas together.

Most of the time I'm not in Italy and I have not kept the design of the pcb, very often drawing the tracks directly on the pcb. I want to remind you that the sensor stage is made up of a high gain amplifier that can easily oscillate, so it may be best to separate this stage from that of the CD4046 if you choose this solution.

Thank you Mr.FrancoItaly. :)

I have already unshakeable decided to make your HEF4046 PLL-LRL version and i hope i will be lucky hands. I take responsibility for inform you about my LRL experience with your PLL-LRL.

Mr.FrancoItaly help me please to precise identify all components you had placed at top side of PCB. I wll do the best i can to redraw your original layout from the soldering side. With your help (and other good fellows here), I think i will be lucky and I will make correct and very accurate HEF4046 pcb.

https://image.ibb.co/ho67GG/Immagine_004.jpg
Please watch picture and mark all components one by one at top side of pcb, you think is valid. Than i will using your original pll schematic attached above make soldering side tracks and joints, and together we can try to redesign your pll version and publish all data for further builders.

I have all i need to make your HEF4046 PLL-LRL project working and testing. Also please give me instructions how to tune this PLL version, what tune first, what middle, what at the end after soldering all components.

I remind you i already have test polygon with some silver and golden targets at 30 cm deep soil in home frontyard, 2 years old and i hope signals are good according to your words.

If you wish, help me make this project running, because i know HEF4046 possible discrimination targets by comparing the phase and amplitude variations of the phenomenon signal is best and the most precise way for long range location.

I also have oscilloscope 2x 20MHz with all equipment i need to easy tune this build. If you think i should shield high gain amplifier that can easily oscillate, please let me know. Also let me know your adjustment tricks. This device could design only very, very experienced e.engineer and very experienced LRL man, like you are Mr.FrancoItaly. :)

Thanks again for your best HEF4046 PLL-LRL project on this site and good luck. And i wish you many golden coins in your Italian treasury.

Best Regards :)

The sensor stage: For display stage I suggest the 3 leds version and change P2 from 470K to 1M and R1 from 150K to 56K, P1 from 22k to 4.7K and add 2 x 8.2K resistances, one from +12V and P1 and the other from ground and P1. The purpose is to make more easy the threshold operation but depending on the output value of the sensor stage you have to change the 8.2K resistances, i.e 10k/6.8K or 15k/4.7k or others.

FrancoItaly does this simple teardown, worth also for HEF4046 PLL-LRL version or only for your 8Mhz quartz version ? :)

https://image.ibb.co/dXjBRG/display_stage.png

Question:
1. Does R2 should be increased from 220K to 470K, 560k, 680k or even 1M or not ?
2. Does C1 should be increased from 22nF to upper value 47nF, 100nF, 470nF or need stay the same value or maybe less ?

ps Dubulumach:
If there is inversion signal problem with output from HEF4046 (leg 2 on schematic above), could be solved easy by puting NPN transistor BC183C in emmiter-follower configuration and inverted signal by 180 degrees, picked directly from low impendance emiter transistor's leg in single joint point with 1st low pass filter stage R3-C4, and after the LF filter to non inverting input (plus sign) of LM358.

I think putting additional amplifier with transistor T5 as BC183C in high gain amplifier stage, could give more amplification and easy the job of HEF4046 ic - phase and amlitude measurement.

Mr.FrancoItaly what do you mean about my little tips ? :)

This is for 8Mhz and for CD4046 version, R2=220K and P2=1M, C1 is no critic but high values (220nF or 470nF) could slow down the search, I think 47nF is the optimal value.

[Dubulumach]

Thank you FrancoItaly. :)

Integrator stage is critical for correct speed response.

Would you like to help me to identify all components from your 4046 PLL-LRL picture attached above in my pre-previous post ?

And one personal question: What do you think about PDK version 2,3,4 from Mr.Morgan from Portugal ? His PDK worth 5K pound (sterling) building and tuning or not ?

As I said I'm not in Italy and for at least a month I will not come back and still stay a few days. The lrl CD4046 version is also in Italy in my lab and I do not like the reverse engineering (also of my project), also because I did it several years ago and I remember very little about that project. I suggest you make the printed circuit for the 8Mhz version with the exclusion of the oscillator part (double face pcb with bottom face connected to ground) and on another PCB the part related to the CD4046 and make connections with shielded cable.
I'm not familiar PDK, several years ago I built but without success.

Thank you for your compliments. I want to remind all new members that the "phenomenon" is still a mystery not recognized by "official" science and that it does not seem to behave the same way in various countries around the world. Even in Greece there are those who managed to make it work and who did not succeed. It is necessary to say that for metals shortly buried the intensity of the phenomenon is weak and it is sufficient to adjust the threshold for a sensitivity just below the maximum that the signal disappears. That is why it is important to calibrate the lrl for maximum sensitivity before the self-oscillation.

This is all the material, the only PCB is that related to the sensor stage and is the most critical one, the other PCBs can be made in several ways. I work in the old and I do not use the PC to make schemas and PCBs, almost always drawing directly on copper, so I have no drawings of other PCBs.

[Dubulumach]

FrancoItaly, Thank you for your valuable informations. :)

Does anybody here know what "the phenomenon" exactly is ? , and how LRL man should behave in strong "phenomenon field" ?
I have heard from the different sources, that in the nights of full moon, there are colorful "fire tongues" rising from the depths of underground where the old treasures had been hidden. Some people called it "the COLD FIRE phenomenon"

Please, good fellows here, share with us new LRL novices about your practical experiences. And of course instructions and tips how to find and detect "phenomenon".

Franco, does will change something if I put for example 4 mhz oscillator at the place of 8 mhz or there will not be big difference in catching phenomenon?

Does it mean that "phenomenon" is not frequency dependent ?

What about the gold frequency 60kHz-70khZ ? How is it related with HF quartz oscillations ?

Dubulumach

I don't think that there is a direct connection between phenomenon and quartz frequency.
I'm also not sure there is a frequency or band of frequencies related to gold. I think the phenomenon can interfere with a wide range of frequencies, from VLF to infrared. My lrl receives signals in the bandwidth of 100Mhz but I do not think there is a transmitter that transmits on this frequency, otherwise pointing it in the direction of the broadcaster would be a strong signal, which does not happen. However, if there are transmitters or repeaters in the vicinity, the lrl is practically unusable. In large lines this is the operation of my lrl (I refer to quartz version):
a small part of the signal from TR1 is amplified by TR2, TR3 and TR4, D1 and D2, TR5 make the signal continuous. the phenomenon is received from the antenna and applied to TR2, the heart of lrl. Mixing occurs here, somehow the signal coming from the oscillator is increased as amplitude and this results in an increase in the output signal. The signal from the oscillator to the base of TR2 partially goes to ground through C9 and C10 (and also L1). In the presence of the phenomenon, the signal that goes to mass decreses and then increases that is amplified by the transistor.

[Dubulumach]

thank you Francoitaly

Yes, if your words are truth, than "the phenomenon", should be some kind of noble metal noise, beacuse it has very wide range of frequencies, from VLF to infrared, and maybe much much higher.

My questions for you FrancoItaly

How did you connected two side antennas, to main lrl telescopic-whip antenna ?
https://image.ibb.co/kjiKYw/photolrl.jpg

Whay you didn't used very high gain, very high impendance, darlington structure from two bc183c, with 10Meg biasing resistor to catch very tiny phenomenon signal at input.

https://upload.wikimedia.org/wikipedia/commons/thumb/7/78/Darlington_pair_diagram.svg/133px-Darlington_pair_diagram.svg.png

M thinking, tell me that the Monocrystalline Silicon Crystal was directly responsible, for detecting tiny phenomenon from gold, silver and other precious metals. I think it is directly proportional with volume of silicon. Biger Monocrystalline Silicon Crystal, should give better detection of phenomenon, because there is greater number of phenomenon particles interacting in same unit of time in volume of Monocrystalline Silico. This imply that we must use many bc183c hf transistor in parallel, to increase effective volume of detection area.

I think that the best thing is to build my lrl and check the good functioning in your country, only after that you can think of improving it.

[kaligula]

I was playing now with RC constance by variable capacitor and with straching the coil, so there is no big difference of the signals whose is catching. So the phenomenon most be here. By the way I was reading user manuel of one simultaneous device, so it's saying that device is working only from east to west or vice versa. What do you think Franco?

[Dubulumach]

Done.

your lrl is working, now i need tuning to achieve long distance detection on small targets. :)
i am working at several projects not only yours in parallel. for example my signal analysis circuitry use 3 bargraph with 30 led diodes for gold threshold detection, while the best variant is 10 bar graphs or lcd screen.

polarity of detected incoming signal depend of input coil winding direction. it means in once case when your touch antenna with one hand or both, signal at output would decay, while in other case, will rise. it seems to me that gold signal noise is bipolar in nature.

Tell me does your lrl react only on gold and silver or also on minerals and valuable constituent ores.

I am novice in gold LRL-PD detection, so need reference manual how to search and detect gold with LRL-PD. If your like help me to find a gold.

I never forget good friends of mine. For 1000 kg gold wealth, 100 kg gold is nothing matter for my good friend who helped me to become a rich man.

According to my experience (and others) the sensitivity is maximum in the north / south direction, minimum in the south / north direction and average in the east / west directions and vice versa. I think south of the equator turns in direction, that is, the maximum sensitivity in the south / north direction.

As I said, I have little experience on real field research. However, I think the lrl are sensitive to almost all non-ferrous metals, certainly to the most interesting ones, that is gold, silver and copper.
As for the sensitivity to small objects, the only experience I have is the revelation of a brass cartridge about 1 m away and buried a few inches. I think the distance depends on both the target size and the burial time. The depth of detection is no doubt higher than that of the metal detectors, in fact many times I had a good signal from lrl but my metal detector was silent.

[Dubulumach]

Thank you very much FrancoItaly. :)

Yes your lrl design is working and working excellent. Quartz version. I think you again have right. The distance depends on target size.

Soon i will finish hef4046 lrl version and try at test field.

Question, for you
Does at output of sensor stage, at collector T4 BC183c at point "X" should be pure sine signal like in quartz version, or impulse signal, or something else, and if yes sine, how to achive this ? How to tune and adjust hef4046 version ?
http://preview.ibb.co/dvQpLm/CIRCUIT.jpg

As i already have read at 4046 lrl thread, you have told lrl man Geo that his oscilloscope snapshoots are not good. Not valid. Would you like to draw correct oscilloscope signal waveforms at characteristic points of hef4046 lrl circuit. For example draw on paper, make snap with mobile phone and post here or more easy download attached picture and draw characteristic signals of yours tuned HEF4046 lrl, with windows paint program. I need these snapshoots because i all tuning and control i make with oscilloscope.

What is the best variant for hef4046 lrl antenna, coil or short-circuit stylus-whip antenna?

Sincerely :)

Sincerely :)
Dubulumach


It is difficult to observe the waveform at point X as the oscilloscope probe affects the amplitude of the signal. I suggest adding the TR5 stage (I'm referring to the 8mhz quartz version) and having as reference DC voltage, waveform is not important, also this output will be useful later for the comparison between phase variation and variations of amplitude. As for the 4046 I recommend using a frequency of 2.5Mhz, higher frequencies, to the limit of the chips possibilities (at least that in my obsession) cause an excessive absorption.

[FrancoItaly]

However I'm not in Italy and I do not have my own lab available, but I remember that in the sensor stage the oscilloscope was virtually inoperable. It concerns the type of antenna, is substantially equal, but the stylus antenna allows to increase the sensitivity only stretching it. You can also use multiple antennas connected together.

[Dubulumach]

Thank you FrancoItaly

You thought adding the TR5 stage as emitter-follower to hef4046 version and take signal without rectification to input of phase comparator or something else like more amplification stage with grounded emitter bc183c ?

I have tested the Quartz version at my test polygon with seveal silver coins and small gold necklace 30 cm in deep, clean soil. I have got strong signal after tuning input coil inductance, about 2,5m - 3m from the targets. Both targets are at distance more than 1 m from each other. Other test via hand near the antenne 5-10 cm, signal drop at outpu of dc stage. I am using long aluminium handle, grounded to minus pole of battery, like in your lrl.

Multiple antennas connected together electrically each other or via small variable capacitors ?

About observation of waveforms at point X., no need for direct contact with point X, just put the sensitive high impenadance oscilloscope probe couple of milimeters near collector and waveform is at the screen withouth affecting amplitude of the signal.

I am thinking about some kind of AGC auto-gain-control circuit for oscillator quartz version, simple give so much attenuated signal from oscillator to base of TR2, untill we maintain some good detected signal level at output of rectification stage.

Does amplitude of detected phenomenon signal is dependent from the sorts of noble metals ? If yes THIS COULD BE USED TO MAKE SOME SORT OF DISCRIMINATION compare it with some initial values from silver and gold targets at given distance, using very precise dc voltmeter x.xxxxx precision instead of display stage.

In my opinion, the quartz oscillator signal is already very stable and therefore no automatic amplitude control is required. The phenomenon simply causes an increase in signal output and it is not possible to obtain discrimination by observing only variations in amplitude, even in metal detectors, it is also important to consider the variations in phase amplitude as well as the variations in amplitude.

[Dubulumach]

In my opinion, the quartz oscillator signal is already very stable and therefore no automatic amplitude control is required. The phenomenon simply causes an increase in signal output and it is not possible to obtain discrimination by observing only variations in amplitude, even in metal detectors, it is also important to consider the variations in phase amplitude as well as the variations in amplitude.

You haven't understood me FrancoItaly.

Not quartz oscillator amplitude control, but mixing amplitide control, which going from oscillator via several small serial capacitors 1pF to the base of tr2 bc183c. This place is main phenomenon detector.

Amount of oscillator signal is enough to suppress phenomenon signals which are bipolar in nature. In once case we have rising and in the other decaying control signal at the dc output of the sensor stage. In simple words mixing both signals - from the oscillator and phenomenon must be dynamically or variabile in accordance with some threshold of dc output amplitude.

We dont need suppression of phenomenon signal via constant amount of oscillator signal, nor undetected phenomenon signal. Mixing amplitude should be additive in some variabile values, small variabile offset, to maintain constant dc offset in some useful range for example from 3.05v - 3,75v at the output of sensor stage. We dont need overshooting or undershooting control dc volatge which is phenomenon amplitude modulated.

My opinion does not change, in the mixing stage there is a "mixing" between two signals, one of constant amplitude (quartz oscillator) and the other of variable amplitude (the phenomenon) and I do not see how it can improve. It should also be borne in mind that even getting an increase in sensitivity to the phenomenon, at the same time it would almost certainly be a appearance of the compass effect.

Francoitaly keep in mind that appearance of so called "the compass effect" is due to very high dc gain. Lower overal gain and lrl going out from "the compass effect". It is artificial effect made by us not the phenomenon.

Also, you have no proof that the phenomenon amplitude is variable at a given area of prospecting. Maybe phenomenon amplitude is mainly constant, while on some unknown way rise or decay amplitude and phase of oscillator. In my opinion phenomenon noise has unknown bipolar nature, very wide bandwidth and maybe have some unknown 3rd component which change both amplitude and phase of lrl reference signal.

There are only to ways imho to explain such odd manifestation of phenomenon signal at referenced oscillator signal. They are speed up or slow down charge carriers (electrons-holes) migration through the base-emitter juntion of tr2 bc183c transistor. It means increasing or decreasing emitter current of tr2.

We should easy monitoring this variations by simply puting current transformer around emmiter leg withouth affecting amplitude of the current, and amplify that tiny current by 3 lm358 op amps in the differential configuration.

The question is one: Does phenomenon signal or phenomenon noise is current or voltage dependent or both ?

The causes of the phenomenon are practically unknown, but I think the compass effect has much in common with the phenomenon. In fact I realized that the phenomenon was real when I realized that my lrl was sensitive to the compass effect. To make a comparison, imagine that lrl is a boat that navigates by following the current of a river (this current could be the solar wind flowing in the north / south direction). If there are no obstructions the boat will proceed regularly (there are no signals revealed by lrl). If there is an obstacle (a big rock) close to that point the current is no longer uniform and the boat is warned of a change (the lrl emits a signal). If the current is uniform but the boat changes direction even in this case you will notice a change and this is the equivalent of the compass effect. For this reason, I think it is very difficult to increase the sensitivity for a buried metal but not for the compass effect.

Everything new in fact had been long standing discovery, made long time ago before us, long standing in darkness of official ignorance. :D

My countryman Nikola Tesla had discovered same effect more than 100 years ago. Father of my grandpa had been asked by Tesla in 19th century to join him in his journey and electricity research in America. He had refused Tesla's offer. In that big country Tesla had revealed that he had made a number of surprising discoveries in the high frequency electric field and that, in the course of his extensive experiments, Tesla had become convinced that he propagated frequencies and electric fields at speeds higher than the speed of light.

Tesla showed all in his patent "ART OF TRANSMITTING ELECTRICAL ENERGY THROUGH THE NATURAL MEDIUM" No. 787,412, filed May 16, 1900, in America, that the current called by him telluric current of his magnifying transformer passed through the earth’s underground volume with a speed of 471,264 km/s, while radio waves proceed with the velocity of light.

Tesla holds however, that our present "tv and radio waves" are not in fact the true Hertzian waves, but really sound waves. He had informed us, that he many times in his experiments noticed, of speeds several times greater than that of light, and that he had successfully designed equipments with which he had been able to project charge carriers with a speed 3.14159/2 time faster that of the speed of light.

Now if you do some calc you will notice that time such telluric wave elapse through the entire planet to antinode point and come back in starting point is 11 Hz.

Well than remember latino american engineer Alonso and his discovery of phenomenon and square wave pulsing so called his "Ionic chamber" with frequency exactly 11Hz and all boulder dash will stand at right place in your world outlook. :)

Certainly the subject is vast, I know in a superficial way the findings and theories of Nikola Tesla and probably the phenomenon is also part of these. But I'm a simple hobbyist and all this is beyond my reach. The only thing we can do is proceed through attempts.
I have already tried to realize the "Ionic chamber" of Alonzo but with no results, however I remember that lrl was not only sensitive to gold but also to other metals ... like other lrl.

I have just came back from ancient earthed Roman town. Two phantoms - lrl quartz version with your original pcb layout, PI and VLF detector make part in my journey.

The first impressions - great place, unknown to many t.hunters. A lot of good signals with your phantom lrl , FrancoItaly. I like night prospecting and digging in full darkness. Lot of Roman bricks have dig out. Very probably ancient roman town or roman military fortress. The great number of lrl signals on some places 3 led diodes has full lit. With maximum dc amplification compass effect imminent. Also both lrl sensitive to ground with almost maximum amplification but without the compass effect.

Need further lowering sensitivity for normal prospecting. Dig up to 80cm with vlf DD sonde 38 cm , no usable signal. Also small 10 inch PI sonde not usable signal. Estimated target depth more than 1,5 meter in soil. The strong signal disappeared when the top of stylus-whip antenna was over tha possible target. Conclusion is very deep target, 3 led lit at full brightness. Scan area about 50cm in diameter with the hole of same size.

Francoitaly any idea how to G.E.B your phantom lrl - quartz version for fully rejecting highly mineralised Roman soil ?

How to estimate probably depth of gold and silver targets ?

ps. both lrl high tech tunned only for gold and silver coins at test polygon 30 cm deep before any prospecting job.

ps.1 posted alonso gold leaf cavity resonantor at 11hz because need additional modification of your lrl with some useful type of discrimination noble targerts.

ps.2 i have forgot to say about 10-12 UFOs tracked my activity from the safe distance. Maybe your lrl on some unknown ways ineract with alien hi-tech equipment in their space ships ? 10-12 UFOs all have been highly orange illuminated. In my oppinion they are very big space cruisers. All till the one flew without any hearing noise. I bet in 1 kg gold all ships have full invisibility to human eyes spectrum.

ps.3 What do you think about attaching alonso golden leaf ionic chamber to your lrl and pulsing the leaf with estimated telluric underground Tesla waves about 11 times in second ? Alonso's magnetic copper loop antenna is very interesting to be attached at front end input of your lrls, both versions - pll and quartz instead stylus-ship antenna and tunned for resonance in 120-140mhz band.

Francoitaly, i think we need some kind of antenna / coil stimulator for your passive rf sniffer, like it was for example in form of alonso's golden leaf ionic chamber and which is also implemented in Mineoro 2000 special series lrls.

In Alonso's case instead RF, resonator use Tesla telluric waves which produce surface acoustic waves of golden leaf resonator. i think dimesnions are very important for correct functioning lrl device.

As I have already said I do not have much experience in research so I do not know if you can evaluate the depth of the buried metal. The fact that the signal disappears on the vertical of the target is normal. I have never experienced a disturbance of the ground but rather a sky effect, ie the appearance of a signal by lowering or raising the lrl. However this effect is connected to the compass effect and disappear together by lowering the gain. As for the coil stimulator my first functioning lrl in practice it was a PI, a 60Khz pulse oscillator excited a resonant coil at about 5Mhz, the receiving coil, arranged perpendicularly to reduce the signal. The signal of the receiving coil and that of the antenna (V-shaped) were mixed in a toroidal transformer and sent to amplifier and sampler stages. The transmitter coil was the same as the oscillator at 8Mhz in my last lrl but according to me it was not useful for operation, or at least it is more complicated to realize and to fine-tune. We can say that the first exemplar of lrl built by Alonzo was a commercial metal detector modified with the addition of a ferrite coil, which was the receiving antenna. In my opinion, all lrls are of a passive type and no signal is transmitted, there may be some kind of filter to highlight gold but I have doubts about their effectiveness.

Yes i think exactly on that continuous appearance of a signal by lowering to the ground or raising to the sky the lrl stylus-whip antenna as you called it sky effect. Overal lrl gain should be lowered enough, to avoid this unpleasant sky effect. I also have very strong signal with your quartz lrl - (all 3 lrl's led diodes fully lit), something about 40 meter in distance to nearest earthed roman tombs, while in previous prospecting area, several days before over the earthed tombs, magnetometer power supply unit has burnt from the phenomenon force rising from underground.

Here is some info for you and lrl builders about Tesla telluric currents or telluric waves or golden waves detector. :)

Long time ago it had been reported that Nikola Tesla made a device which allowed him to hear sounds at very great distances. I have never seen any Tesla's details about of the circuitry used by Nikola Tesla. But in 1986 year, american Dave Lawton has produced such a device, and he reports that he could hear human conversations taking place 4 1/2 miles away from him or 7,2 km. Interestingly, the sounds from 7,2 km were also travelling through a solid state stone wall some three feet thick cca. 90 cm.. The circuit for this device is described in Radio-Electronics Magazine in April 1986.

http://www.free-energy-info.com/Ch11/Fig15.gif
The circuit shown here comprising of two 741 operational amplifiers connected as a two-stage amplifier. The unusual feature is very small amount of white noise being injected at the piezo tranducer at input of op. amp. The white noise is generated by the 5 volt zener diode. The level of white noise is controlled by 1.5 Meg variable resistor, plus the 10K fixed resistor. While the range of these two components is 10K to 1.501 Meg. the working setting is normally very high and so only a very small amount of white noise is fed into the input of the first 741 op. amp. to modify the tranducer input. The adjustment of injection of white noise is the main control here, and it has been found experimentally, that when the tuning or pot.setting is correctt, the circuit has the feel the strange telluric echoes from positive op feedback. This device is is operated by turning the gain high up until the op. amp. just reaches self-oscillation, and then backing the gain off very-very slightly. The white noise source is then adjusted until the unit is producing a echoing of the sound. The result is a device which has hear Tesla's telluric waves.

I was changed both variables, input coil L inductance and variable capacitance C at input of PLL-LRL. Also lenght of stylus-whip antenna is variale inmy case.

Also i was implemented GEO modification, by precise trimming amount of mixing pll oscillator signal from pins 4,6 to the input of 3,3nf capacitor via 20 turns vishay variable resistor 10K. The main trick is in a exactly correct proportion between two signals - from oscillator and what came through the stylus-whip antenna, because the device pick up many non electrical signals with unknown origins.

I need to know correct dc offset after 3rd order LP-filter to adjust 3 x LM3914 to cover entire signal range with minimum meassuring steps.

Would you like to help me TO ADJUST IT ONLY FOR GOLD ? :)

If youl like post your Infra-red LRL and i will try it in a practice on roman's earthed towns and fortresses.

I do not know how to calibrate my lrl to reveal only gold (I don't know if is possible)), I also have no more place to test with gold.
I did not try my lrl with infrared, I just gave some theoretical advice. to correct dc offset after 3rd order LP-filter you can sum it to a suitable DC voltage via an LM358.
Step by step instructions and improvements for my LRL-PLL are the same that 8Mhz version.

FrancoItaly does your LRLs detect a spark from 1.5V AA battery to 60cm ?

Have tested your hef4046 PLL-LRL version almost whole day. Very strange behaviour. Very lot of time to tune only for gold target. When find a gold signal device auto-lock on target. All 30 diodes have lit. Changing direction of stylus-whip antenna to any other side from gold target does not change nothing, with locked signal phase approximately 5 seconds, than after that immediate disappear or lock-off. Pinpointing work not when top of antenna is above the target but when a lrl-man is above the target with his back. Any human bio-field or human aura near lrl-man up to 5 meters and of course not possibile to detect anything. human aura suck golden signal complete.

I need to say i tune with 7 variable at once.

P1 vishay potentiometer 100k - 20 turns for frequency. With 5P variable capacitance and very low inductance cover over GHz range. Phenomenon also depend from frequency and many other variables.
P2 -ii- -ii- 1k - 20 turns for sensitivity, tune the ammount of signal comes mix with gold signal to C10 560P and base of TR2 BC183C, with beta more than 700.
P3 -ii- -ii- 20k - 20 turns for signal threshold at non-inverting input of ic2a lm358
P4 - ii- -ii- 10k oscillator amplitude adjust between legs 3-4 and leg 9 with viper to the input of C3 3n3. I can tune output pulse amplitude in microvolts range. Checked with oscilloscope. TR1 BF240 with own beta less than 100. TR1 has no biasing resistor 100k or more to common conductor.
P5 - ii- -ii- 10k FSD potentiometer tuning full scale display for 30 led diodes.

C11 variable capacitor 5p to 145p from old japanese transistor radio receiver, instead fixed 22p ceramic capacitor. Fine tuning vith big plastic wheel for tuning same radio.

L1 coil 3 turns wire 1 mm in diameter, left winding or counter clock wise wounded over 10mm drill bit. Tuned by stretching and compressing coil lenght.

stylus-whip antenna 1m long tuned to variable lenghts with telescopy.

ps. gold tuning or other metal tuning is frequency phase dependent. :)

ps1. sparking battery associate me with very low energy photons above the long earthed gold due to influecne of telluric waves. on some strange ways gold make unheard flicker photon noise deep under noise floor of background ambient field. :)

Telluric Radiation Photography by Dr.Paul E.DOBLER

Dr.Paul E. Dobler of Heilbronn, Germany discovered that turbulent water emits powerful bursts of energy in the millimeter spectrum wave band. Turbulent motion of water generates billions vortexes which act as microenergy transmitters. He had also discovered that energies in this waveband could cause metallic crystals - for example gold, silver, copper, brass, zinc etc. etc. to emit low energy photons which will expose certain tpes of chromatic Infra Red film. He made interferometers, resonators, and other devices that could accurately measure millimeter wavelengths that are emitted by those crystals.

The exact techniques used are described in his two books:

1. Biophysikalische Untersuchungen uber Stralung der Materie, Wunchelrute, Elecktrische Wellen - Biophysical Experiments on the Radiation of matter, Divining Rods, Electric Waves, 1939

2. Physickalischer und Photographischer machweis de Erdstrahlen Losung des Problems der Wunschelrute - Physical and Photographic Proof of Radiation from the Earth, 1934.

ps: All of these were induced by Tesla's Telluric Currents which were caused by our ASTRA SOLAR (not black light energy projector called "sun" as many think and elude real knowledge), main source of power in the center of our planet which is above our heads at 6300 km. YES we are living in the planet, not out of planet, as normaly nobody build the house to live at roof with family. :)

Alonso's gold leaf resonant cavity bug

Singing gold tongues
http://www.longrangelocators.com/forums/attachment.php?attachmentid=11279&stc=1&d=1266326751

ps: To use Alonso's gold leaf resonant cavity bug, excite the cavity with a very strong and clean sine CW RF carrier and receive the "gold resonanated" FM audio at 3rd harmonic of CW RF carrier. Than recover the "singing gold audio" as a doppler shift mixing the outgoing frequency with the incoming frequency in a diode mixer. The cavity's stylus-whip antenna is low Z, so it can be used for testing at gold targets field. Knowing the properties of Tesla's Telluric waves and their modulating frequency of 11,3 Hz we should be able to recover "singing gold audio", out from background noise floor. :)

ps1: Also piezo speakers and SAW surface acoustic wave filters could be used as sensors for Tesla's Telluric waves, but the best variant IMHO are IR sensors for example un-etched silicon wafer.
http://image.ibb.co/cai1Fw/Silicon_is_transparent_in_infrared.png
Top image is visible light, showing the 4" wafer, 0.015" thick, on top of a plain tungsten-krypton flashlight. In visible light, it acts like a mirror, as seen by a Pentax K200D with its ordinary infrared-blocking filter. You can't see any light from the flashlight passing through. In infrared light, you still see some reflection, but a lot of the infrared from the flashlight is coming through too. This is seen by a HPR707 point and shoot camera, modified to see IR only. Now instead tungsten-krypton flashlight imagine golden fire tongues, induced by Tesla's Telluric currents in underground.

ps2. FrancoItaly i am counting on you and your long LRL experience. :)

FrancoItaly LRL quartz-pll ALSO USE LF pulsing bY BEATING 120MHZ LC tank input oscillating circuit with 15 overtones of main quartz frequency. LF beating is result of both and it is that what interact with Gold Target Tesla Telliric Currents (waves) which are automodulated/synced by earth itself and coming from a very long distances longitudinally to target. It further means FrancoItaly lrl could hear an "gold echo" directly by searching from NORTH-SOUTH or reverted from SOUTH-NORTH when target gold signal change sign or phase for pi or 180 electrical degrees and become negative. In that case output amplitude gold signal sudden drop. Knowing this you could discover hollow treasure cave or hollow gold depo deep in underground where signal many times make echoes reflecting from the walls of hollow earth caves.

Keep this info in your thought.

Also very small and very fine rain drops not to velocity speed falling improve FrancoItaly LRL detection distances. Checked by me. I just came from rainy lrl prospecting and lrl gold hunting. The place is odd, strange and i have not got any usefull gold signal. Will continue next days.

As you can see this is my EEngineer knowleadge and I am not a ***** like some members here and i am shearing my good ideas and knowleadge which i recommend all to to also like I did.

I built CD4046+Pwer+display, but unfortunately its battery consumption is very high and don't work correctly with 2 or 4 9V. Do you have any suggestion for solving this problem?
What type of battery or power do you propose?

[HaFar2010]

http://s8.picofile.com/file/8313827118/panel.jpg

Please see the my panel of Franco's LRL.
There are three LEDs in CD4044 (one LED) + Pwer/display (two LEDs) (attached). Can you tell me what is function of blue LED (in CD4044 circuit )?
In my LRL, beep only is heard by rotating Gain screw, not by Threshold. If possible, please guide me how to caliber the LRL in real environment.

Thanks alot.

Hi Franco, instead of using a 22p capacitor of 20 p, will there be a problem or is it 22p good?

No, my lrl works well from 0pF to 33pF, there is anyway the parasitic capacitance of base/emitter junction of TR2 (about 10pF).

This answer is for maziio, that sent me a private message but I can not answer him:

I have simulated with multisim and the sensor stage works with BC183C or BC183B or equivalent but obviously it is not possible to simulate it completely. Essentially the sensor stage is composed of a high gain amplifier (TR2-TR3-TR4) that amplifies a small part of the signal coming from the 8Mhz oscillator and that is what can be simulated. The "heart" of the lrl is centered on TR2, where the mixing between the 8Mhz signal and the signal coming from the antenna takes place. The main difficulty is to prevent the whole sensor stage from becoming an oscillator and at the same time having a good amplification. On the forum there are some PCBs posted by members that include the whole lrl. In my opinion it is better a separate PCB for the sensor stage, better if double-sided and this is what I did.

You'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.

Hi
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.

[FrancoItaly]

Hi
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).

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 ,

The values are correct, I think you have read the helps. what still needs to be established is whether the gain is sufficient. To verify this, increase the gain until the compass effect appears, then decrease it until it disappears. Try R1= 69K, R2 = 100K, P2 = 1M.
The best antenna for me it's stylus that which can be extended up to 60cm with increased sensitivity.

When you remove the quartz the TR5 emitter must be zero, if not it means that the sensor stage is self oscillating. If this is the case you must decrease C13/C14 (470pF or 390pF or less).

Surely there is a self-oscillation. This is the operation of the first version of my lrl. Touch the antenna and check if the signal varies. If so, if the signal is stable, the lrl works equally this way. To decrease the gain increases R10 / R12 (1.5K or 2.2K). Self-oscillation can depend on a parasitic coupling of the pcb and / or the excessive gain (beta) of the transistors.

[QUOTE=FrancoItaly;156419]it's not critic, about 10mV - 1V or more.[/QUOTE


Thank you very much for your guide

In your opinion, with these conditions my lrl is ok?
Can I put it inside the box?
The box with aluminum foil does not create capacitive capacities?
What is lrl reaction to the target?
Or, by placing the L1 vertically, the sensitivity to the north pole and south will decrease?

yes but if is necessary you may increase gain by decreasing R17 (from 150K to 47k), by increasing P2 (from 470K to 1M)
You can put the lrl in the box.
The shield do not disturb.
The target increases the DC signal (sensor stage output)
I think that the L1 place is not important. Too much gain causes the compass effect.

hi franco dear
What do you mean by r17?
Is the same r1 in the display stage?
Thank you so much.

This is the schematic, yes I refer to display stage (3 leds)

I ask Panos Pappas few details on the type of metal and even distance is revealed. To Mustefa I said: good work.

hi franco dear
Should lrl have two antennas?
I installed an antenna one meter.
Are the leds turned off be exactly above the target?
Thank you so much.

An antenna works well.

Yes the signal goes off about above the target.

Hi Zixelll,

I respond here because your inbox is full:

The stylus antenna is better because you can increase the sensitivity by lengthening it.

This voltmeter is not suitable, as I see it has 500V full scale. My lrl is designed for led display.

Hi dear franco
Thank you for sharing your lrl.
What is your orginal pcb size?
Thank's

[toorani]

hi dear franco
I put lrl in the box.
My lrl responds to some things,for example:
Thermal glue,Refrigerator engine,Lamp,Gas stove lighters,Oscilloscope.
In your opinion,This is the correct performance?
Thank you very much for your guide

These are roughly the original dimensions, however the dimensions are not critical, especially if you use the double-sided pCB.

My lrl has a high gain amplifier and any rf source may disturb, then this behavior is normal.

hi dear franco
Is it possible to reduce the Voice of buzzer?
Thanks dear Franco.

[FrancoItaly]

hi dear franco
Is it possible to reduce the Voice of buzzer?
Thanks dear Franco.

There are several possibilities:
- use another type of buzzer.
- put a resistance in series to the positive or negative of the buzzer, the value is to be tested.
- put the buzzer inside the box, in this way the sound is attenuated.
- I use a switch to exclude it.

Hi mr fracco
And thank you for members guidance
Mr franco what kind of adjusting threshold is true?
I meaning is that how we adjust LED threshold OFF towards surrounding?
1-when anten is front and horizontal?
2-or anten is to the sky and vertical?(and neutralization of sky effect)
3- or else way?
What way is best and standard to searching and detecting targets?(Hi sensitivity and correct way)
Thank's

If the lrl is well adjusted there is no compass effect, normally the antenna must be parallel to the ground and the threshold must be adjusted to get the first LED off, approaching the target you need to slightly tilt the antenna downwards (to get the maximum signal), the signal disappears completely around the vertical of the target. All this moving in the north / south direction, in this way the sensitivity is maximum.

[afshin]

Thank's mr franco
But in this way ( parallel to the ground and then adjusting the threshold)when I move the antenna to left and right or downward or upward the LED be ON.Does my lrl work normal and correct or not?
Thank's

If there is not a target Led must be off, if LED is on there is compass effect and/or sky effect, then the gain is too much.

hi franco
after more than 2 year working on your lrl !! i found some thing weird !

i have increased gain (now i am using 4.7n for c13 & c14 ) without self oscillating .(but with a little change )
but no way to increase range from 15 meter i have reached this range with half gain! (15m from north to south and south to north half of range . other directions too weak !) and it senses some places without any metals some times !

antenna length 83cm . sensor voltage around 3.5 volt(decrease it from 3.5 volt will be too hard to work with ! it will be too noisy and increasing it will decrease range .

test for a copper bowl in around 80 cm for more than 5 years buried . (almost same result in real test )

hi dear franco
I put lrl in the box,In terms of conductivity, grand circuit and box is connected to the antenna,Is that right? I feel less sensitive.
http://uupload.ir/files/prks_photo_2018-03-09_11-24-16.jpg

now c1 is two Parallel Capacitor 560p and signal emiter tr1 is 2.4 volt pic to pic 8mhz and voltage out put(emiter tr5) is 4.5 volt but With Change c1 to 560p signal emiter tr1 is 3.5 volt pic to pic 8mhz and voltage out put(emiter tr5) is 5 volt,In your opinion,Which mode is better?
Thank you so much.

The shield must be connected to ground, the antenna must be connected only to C9/C10.
As regard to C1, there is no difference because the sensor stage gain does't change, but if the gain should be insufficient, C1 must be decreased, in this way the amplification of TR3 / TR4 can be increased. Another way is to decrease C2 / C3 / C4 (instead of C1). Keep in mind that the 8Mhz signal is only a carrier that is "modulated" by the phenomenon.
