NOW I UNDERSTAND , THE RADIO AND STIMULATOR WORK LIKE A BFO + ZAHORI

antenna for AM radio ???
there is a receiver circuit with a stimulator oscillator with a coil behind the RX antenna that can use a gold sample for resonance (each metal resonates at specific frequency) , that circuits can work as LRL but cant react to small objects, however the radio circuit is a optional upgrade for more sensitivity to small targets.

sorry , its a FM RADIO, not the AM told before,my mistake

oh man, see how you are completly wrong ...

if I told its not a zahori , becouse is not, ok !?

circuit near the batteries, BATTERY CHECK,one LED open (low batteries), two LED open (change batteries)

circuit in horizontal position,its the FM RADIO,there a variable cap. to tune for the correct resonance frequence

circuit behind the antenna its the receiver and together is there a oscillator circuit where the horizontal coil is connected

little cilinder is the buzzer

example of this kind of LRLs ,you have the DCH85, The ICONOS,the Blue PD of Esteban...

I UNDERSTAND :

A RECEIVER + FM RADIO + STIMULATOR,

YOU TOLD THAT THE RADIO IS OPTIONAL FOR MORE SENSITIVITY FOR SMALL TARGETS .

THE ANTENNA POSITION IS CORRECT IN THE PHOTO OR THE RECEIVER IS MAGNETIC WITH

A FERRITE ???

thats correct

and the 57pf was connected after a previous test with a variable capacitor near the gold medal that shows this 57pf value is the one for the best distance on the target ,then is to put a fixed cap.

I believe the nanovolts are somewere around the targets ,floating trew the magnetic lines,but not understand why they sometimes cant be located in all directions,whats hapening ? If someone here understand about this Phenomenon,maybe can explain,thanks.

Hi abou 2014

In that picture inner loop is like the dch 85 but that is not complete
look at the stephan gold sensor in this forum and oro & plata in the dch85


best regard

HI MORGAN
I made a clon of your pdk with transmitter that is work well
thank you so much for your helps and information in this forum
I Believe the pdk is one of the best lrl in this forum

best regard

Thank you Zakari , Morgan I saw in your youtube chain that you also built an IR LRL, very interesting, I also have an IR LRL version on the right and my left sample antenna

hi abdou 2014
in the left your big loop is the rc concentrate loop like the minero small loop

but the inner loop with sample is'nt correct and not complete
morgan knows my mean

Mr Morgan , I built the TDA with the DCH circuit and with the LM386 and I noticed that with

LM386 has more sensitivity !

did you get the same result ???

I also noticed that with the DCH display there is no need for an audio transformer, I made all

the versions and I learned a lot with the modifications !

Mr Geo said in the forum that the sensitivity should be in the variable LM317 power supply for

15V, I don't know if you did the same thing ???

Hi, I think this lrl of morgan is a static field detector...It is evidence by a wood case....Plus there is also a magnetic receiver via ferrite antenna...everything is excited by a stimulator...stimulator is important to create capacitive reaction...I also think that there is no fm receiver.
Its only my guess...

There are two electric loop antenna, one for TDA and one for DCH85 receiver , I don't think there is a magnetic circuit with ferrite ,
the question is : the TDA and 741 are in series or in parallel ?
looking at a photo of Esteban of the blue PD, there is an IC 8 that has been added to the TDA card, which means something

What is the ferrite circuit? Is it pdk?

In these two photos we can clearly see the addition of the PDK circuit with Ferrite to the DCH

but Morgan don't add this part to his LRL
