PDK LRL

[Esteban]

Hi Fred

Bad news for your PDK project. As you know i made a new Pistoldetektor using your PCB and shematic post on the forum,and after a lot of troubles,now its working BUT NOT AS LRL,i made a lot of tests outside in my field test and in other places without any LRL results near old buried metals. To make it useful to detect the phenomena i think maybe needs complete revision in the schematic.It seams also the Qiaozhi last schematic version as some mistake.
About Max schematic,there is one person in the forum who as made it,and it seams to work very good,but we dont have sure yet,he will inform more.

Regards

What??? Now, your pistoldetector doesn't work!!! If you have the right way, don't understand why do you fail.

You can use fiberglass instead wood. Her a sample of absorptive pistol in fiberglass

Hey!
An old AM/FM radio inside!
cool.

Well, this is consistent with what we told you before, same results as ours....
Hope can be improved.

Amplification stage of radio is cheap and low in consumption. The absorptive part is more complex. I only make reference about material of box. Amplificative stage of radio or tape recorder can be useful.

You understand wrong,its not my PD based in 6 Alonso circuits,i was talking about Fred´s PDK circuits,we are studing.

Now, I understand.

mH-solution

Now, I understand.

Hi Esteban

Do you have any solution for replace the 250 Micro Henry to any knob ,to use outside the wood box. This device needs time to time calibration with a screw driver in the 250 mH,its not confortable always doing this,maybe there is another component to replace the mH. Do you know something?
You can see complete schematic and PCB circuits in the thread "Ionic/Electrostatic energy Field Locator".

You can use differeny way. See here.

Here one made by me. Is the same of drawing. You can see the plastic attached to the ferrite for to adjust it. Small solution for big problems.

[Esteban]

Here detail of other.

But if you're a finest man and need more precisse use the tunner of AM radio (old) for car. This has 4 or more ferrites. You can connect in series for to find the desirable value. I try this and work. But drift of BFO maybe is not caused by it.

[Esteban]

This is a box for pistol made in fiberglass. I hope is better than wood.

[Esteban]

... and a matrix for handle (made for my father for me!). Final handle also is in fiberglass.

I sugest that since this post and other ferrites figures, include AM tunner, must be in another thread of your ionic-BFO pistol.
