Is the information posted on this site correct? Can metal detection with ultrasonic sound? Can you help with this? link is below

No ..... It was a joke.Originally posted by brain View Post -
I don't know about this schema but if you will look at forum will find a post from Esteban where says that "phainomenon" is detectable by ultrasonic technology...Originally posted by brain View PostGeoComment

Dear Friend , here is this two liks , I not build this two Sch , but I beliewe that will works its with correct calibration , for this need Time .Originally posted by brain View Post

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 .Comment

Mr. Esteban, many years ago, had mentioned the method of detection with such a device .. there is nothing certain but why not ..Comment
-
At theory yes....
but remember that he never constructed a workable ultrasonic lrl....

Working of IR receiver and ULtrasonic receiver are also , here different is only wavelight !!Originally posted by Geo View PostAt theory yes....
but remember that he never constructed a workable ultrasonic lrl....
Next critical calibration .....Comment

Yes a theory my friend George,Originally posted by Geo View PostAt 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 ..Comment

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

This system can works also with simple Sound wave , ( but with different connected method ) , itself I not build it , but Before years was have Video in Arabic forum for it and I understand this works method , this method is so like Alonso PD , if any know method for working PD , also can build it . Maybe now any Friends understand how is working method or for what I say .Originally posted by kostas87 View Post

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?Comment

Yes , one is ultrasound (long wave) , other is elektromagnet (more short wave ,Originally posted by brain View Post
here same Logic is receiving Method .Comment

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 ..Comment
