If papanic is real, he must be have details of antenna.

555 timer
what is the lm555 use for and what type of signal .

Looks like it's setup as a vco for audio output.

yes i have
yes i have and you and antreas dont!
i dont give you nothing! this schema is not lrl, is something else! antreas steal but not understand it! ha,ha,ha,ha! you also not understand it ha,ha,ha,ha! yeas i am robert, so what! |

Hi to all My analyze About circuits , Transmitter :osc running with 800khz operating frequency Then buffer bf 244 and amplify with 2n 4427 tr ,simple Filter And then go to antenna . c30 set for maximum radiation , Transmitter antenna length in picture shorter than of λ / 4. Out put voltage in ant. Feedback and buffer and detect then Apply To integrator and level control by 741 opamp . These sections seem as only for power level control that Apply to transmitter ant. Receiver: receive signal from receiver antenna apply to Filter then detect , level tune ,buffer and another level control In second common emitter configuration by Q1 tr. Then amplify by Q4 ,go via R11 pot. To meter. parallel with this Section vco with 555 then audio amplifier with LM 386 IC. These parts all together only filed intensity detector . Please tell me how can this device found valuable metals
from distance ? |

Circuit and gold or what ever
This circuit will not detect gold or silver or my rocks.
JUST LOOK A IT.......WHAT I SEE IS A SCAM>>> AND I DON"T LIKE SCAMS If is works tell what type of sigal gold will give off I want the the output of the the signal the frequency and the voltage and wave form of the signal. ONE MUST KNOW WHAT HE IS DETECTING TO BUILD A DETECTOR. WHAT IS TYPE OF TESTER BEING USED TO CAL THIS THING. A RADIO ANT. IS A SHORT AT THE 200 PLUS GHZ RANGE SO DON'T GIVE ME THAT CRAP. ANYONE CAN MAKE A LRL THAT LOOKS GOOD. TAKE A GOOD LOOK AT THE ONE I MADE. |

Hi again
Anybody tell me what happen on buried metals in ground? If that’s emitted frequency ,what is it ? |

BUT WHAT DO I KNOW. I WILL SAY THIS UNTIL SOMEONE TAKE CARL 25,000 OR I CAN BUILD OR FIND A LRL THAT WILL WORK IN MY HANDS . NOW FOR THE SMALL PRINT. IT IS ALL A SCAM AND IF A SCAMMMER WANTS TO PUT ONE OVER ON THIS SITE WE ARE IN FOR IT. NOW FOR THE LARGE PRINT. WE HAVE SOME VERY SMART PEOPLE ON THIS SITE |

Agree!!!
Agree!
That was my point from the very begining! But those "lrl" boys are so pesty, provoking me with obvious nonsences so i lost nerves oftenly and left serious talking long time ago! Andreas,Esteban,Hung and few more...Heh! Who are you joking here? regards! |

What's in the box Clondike?
What kind of LRL did you make? Looks like you have it connected up to that nice looking commercial signal generator,how come? The reason I ask is normally these LRL's or MFD's come with a built in frequency source.

it seems a resistor box...but with a pretty picoammetter and the whole wood box connected to the white DEVICE! Could be anything analog bridge R or RL and the like not a signal gen. The ratio knob could mean ratio of unbalance in the bridge halves... Looks cool ! Nice! Clondike I like it very much! I have to do one myself... I have a 1920 kvoltmeter that seems tailored just for this! Best regards, Max |

MY LRL and Smart People.
Like I said we have some very smart people on this site.
I am in to old radios tube electronics and I use some old testers to fix my old units. some of my old testers are better than the new hi tech junk. But I use all type of testers.See www.firstontop.com. Yes I use one of them to make my LRL but it will work as good as any LRL. It will not pick up gold,silver,diamounds etc. BUT IT LOOKS COOL, |

Hi!
Hi Clondike Clad,
i have some very old tubes. Ancient ,you may say. Some of them dated from 1934. or even older.Interesting thing is that those tubes are new,never used. I was thinking, if some interest, to make a list and offer to sell or exchange for some other things...Any intereset? I can make a list and few snapshots of those. There must be over 40-50 pieces in original package. If you are interested, let me know. Regards! |

I remember here in the states, in a drug store, they used to have a large upright tube tester. You could walk in and test your tubes. I telling my age now!

What is frequency? I build carl mfd lrl with signal generator that power apply to Ground , in practical test I don’t have Good result . Are you have experience in the matter ? I study very paper , but not have strong and reality basic in The matter . If I obtain good real basic ,than be able design circuit in this way . |

Is it a normal antenna and you use a timer to switch between Tx and Rx or it is a special type???? If you have the antenna details and the schematic is not a lrl then what it is???? I have sheen the detector by Andreas and it works but he dont give me any details about it. And i dont know why he send the schematic to you and not to me ???? The detector is working .... now we want the oreration principle..... does anyone knows....

Geo-a question
Geo,
Very interesting that you have tried Andreas LRL and it worked for you. Can it be adjusted for gold only? I am a gold prospector and part time placer miner. Thank you, Randy |

Frequency is.
Quote:
A good way to see this if you walk 1000 step a minute your frequency would be 1k or 1000 step per minute,now if we use a AC signal and the tip of the wave is positive and it dips to nigitive and back to a positive we have one cycle or one Hz now this happens 60 time a second for he USA and 50 for over the pound.Now some LRL use anything up to 240 ghz now we also have phase difference (power,voltage and current) and we have harmonics and a host of things that can happen with frequency( shin affect resistance .capacitance etc.)On some frequency the signal will cross gaps on circuit boards and wires could be very high resistance or become wave guilds etc.If you don't have much electronics you need to start reading and rereading.( I am still learing. This is a very simple way for Frequency .I know i miss a lot other can help ya. |

Hi Clondikeclad
Thanks for your description about frequency . I am sorry for my bad English .also I am elctronics Engineer and no beginner in electronics .(please see My profile) My intention about “ What is frequency?” is howmuch Frequency . for example carl mfd lrl out put of signal generator Is 5khz for gold prospecting . Are you have success whit lrl ? Or can you found gold ,silver with lrl ? |

does it work ? Please explain what you've seen on the field. Maybe papanic have no permission to post schema, I'd like to see too but I'll respect him if refuse publishing here without permission. Anyway, I think that if it could give some signal from far away metal objects maybe uses some ELF detection principle...that I know is erratic and hard to figure out what produces signal and why! Maybe someone discovered something new about ultra-low freq. generation/resonance due to buried metallic things and how to filter all the noise these devices are addicted to. Who knows ? Best regards, Max PS: it isn't the 800khz driven schematic what you are talking about (on page 1), right ? |

Papanic is RObert and he(they) don't have any information about antenna, no RObert, no Papanic. Awake! Was posted without permission of Andreas.
Now, Andreas learn the lesson. He post the schematic to other(s) and well... |

???
Esteban, stop being smart ***! Papanic is not Me (RObert). I am not Papanic. As far as i know, Papanic is Ioannis Papanikolau from Cyprus,EE, RF. My college.Already met him couple times on seminars! I dont know his intereset about decision to post that schematic here and i dont give a **** about it. So stop acting smart, actually you are looking very stupid here,Scherlock! With same analogy i can claim that you and Hung are same person, since both have simillar ideas,claims and phylosophy! Cant I? BTW Hung is back again so you dont have nothing to worry about?! Now it is gonna be more interesting; a lot of crap again, a lot of new bull**** threads with scam advertisments more here....? God help us! |

They were a lot influenced by rust metals. Now Andreas said that he regulated in order so to detects only gold (and why not after he detected the other metals). It does not interest me if it detects only gold but the operation principle. That we can locate the presence of metal from far. Regards

It was so easy. Turn it on , put the sensitivity to middle or near max and go. You turn the lrl left and right and if you hear a beep you walk and watch the meter for max reading. So easy.......... I have not the real schematic of this detector but as i know the Tx frequency is 800 Khz..... Regards
