Hi all !
Anyone have built this Magnitostriction LRL schematic - ultrasonic type? 99.99% it must work with correctly tunned filters. Where to find electromechanical filters for every metal? Need only 3: Platinum , Gold and Silver. Magnitostriction Frqs: 5,722 Mhz Platinum Pt ============================== 5,621 MHz Aurum or Gold Au difference 101 KHz ============================== 5,278 MHz ARgentum or silver Ag difference 343 KHz ============================== 4,731 MHz Ferum or iron Fe difference 547 KHz ============================== 3,872 MHz Cuprum or Copper Cu difference 859 KHz ============================== 3,245 MHz Aluminum Al difference 627 KHz ============================== ps: Worth try Ultrasonic LRL ! |

Hi Dear Dubulumach , before years I Hear from one my friend that he make a real PD ,
working with ultrasonic , but Schematic was other (also this is public ) , not from this upper Sch . Here important is correct calibration , You know that is so and How , because You are proffesional . |

Mr. Esteban, many years ago, had mentioned the method of detection with such a device .. there is nothing certain but why not ..

At theory yes....
but remember that he never constructed a workable ultrasonic lrl....

But he had mentioned it was tried by Mr. Alonso ..he did not mention failure, or success ... and he did not mention where he placed it to catch the phenomenon?.maybe behind the bfo coils or the heathkit coils.maybe it is as capable as ferrite with the passive receiver ..I thinking ..theories .. |

i didn't find these filter and coil on the net with thses refferences ???

Hello, you said humhum logic is the same as alonso pd. The ultrasonic metal detector uses the specified Frequencies. Does Alonso Pd use negative or positive electromagnetic or frequency? If there are frequencies, what are they?

what frequency..? you say there are frequencies in the phenomenon, No do not support this .... maybe if a device is capable of detecting very small changes in electromagnetic differences from the environment of the phenomenon. Or maybe the environment of the phenomenon to disturb a part of the device and be detected by another sensor located inside the device this signal. The operating frequency of each device does not matter in the phenomenon search .The phenomeno it's a anoder energy ..

Hello friend Hum Hum ... everything you say about IR and Ultrasonics is very interesting ..... not many days ago I spoke with Alonso and asked him if it is possible to detect the phenomenon with Ultrasonic systems and he said Yes .... but I told him that if there would be problems with the obstacles and the detection distance at which he answered me: he told me that it was only necessary to send an ultrasound signal at a low or very low frequency to be able to pass matter and it was the only thing that was needed to be able to detect the phenomenon and that he had done it and it was one of his best detection systems ... he also told me about the frequencies of molecular resonances of gold and silver and copper ..... very very interesting !!!!
.... is what he told me .... greetings |

only for selected metal , so is more good . Does you can find only selected metal (only Gold or only Silver or only Copper metal ) with reject other all metals , when use moleculer Freq filter for selected ? |

It remains to collect, then skim on the shelf, then disassemble for parts. Or act wisely. Forget about this scheme and everything that is written in these magazines.
