You're probably talking about Fabio's first post. I don't have a diagram of it.

[Zicos]

Yes Pahom, I am referring to the first post.

[Zicos]

Does anyone have the diagram that Fabio uploaded? Fabio, are you here?

Hello
Does anyone have the DCH circuit by Fabio ?

The schematic is not visible!!

[abdou2014]

If you understand the principle of operation you can draw a better one than the one you were looking for

[aft_72005]

The DCH85....comes in a few different designs. That's why I'm interested in seeing Fabio's schematic as well.

[Zicos]

hello everyone. in the pictures of the dch 85 there is a loop of thick wire that closes through a resistor and a ceramic capacitor. what are the prices of the components ;;;what is the diameter of the loop ;;;and is it connected somewhere ;;;;;

[Zicos]

For anyone interested, the resistance should be 4.7 KΩ 5% yellow/purple/red/gold.

Capacitor is 150 nF and diameter is near to 4 cm. R as u wrote is 4k7. It is a passive filter and is n't connected anywhere.

Hello Mr. Geo. Thank you. I am asking about the diameter of the large loop that is in front of the head. To my eye, it looks like 10 cm-13 cm.

[Geo]

Sorry my mistake. I"ll looking for...

[Geo]

I found 2 notes, one 11cm and the other 12cm. I don't see any problem...

[Zicos]

Thank you Mr. Geo for looking at your notes.

[abdou2014]

you only swim in audio peak detector a small portion of long range locators schematics and they are hiding the essential from you

[Zicos]

hello abdou 2014. the secrets of an LRL are as valuable as gold from what it seems.hahaha.

[Zicos]

Are the two switches on the head of the dch 85 the samples?

[Pahom]

It seems like it is .Inside the coils are metal samples, something like filters. But the size, number of turns, and weight of the samples are still a mystery.If you have such information and have the opportunity to share it here with the forum participants.

[Zicos]

I don't have the information about the samples, I'm still looking for information. (Are the samples in wire form? Or is it the core for small copper coils?) Surely some people know, but the question is whether they will provide information. Until then, I'm continuing my construction with the data I have and I'll see in the hunt..if it can receive the signal I get with another LRL, it's enough for me for now.

[Zicos]

hello everyone. who knows about the power supply of the DCH 85 ?? why does it use two 9 volt batteries and 12 AA batteries? why 12 AA and not two more 9 volt batteries?? can the batteries be replaced with 18650 ?? what array is for the receiver? does the receiver power supply use lm317 only or does it also use LM 337 ?

[Zicos]

I finished building my dch 85. The video was uploaded to shorts and I can't paste it. Go to my YouTube channel to watch it. Does it work like the original?

Put the link here on the video. Thanks!

should it also detect a 1.5 V battery spark, and if so at what distance?

Not bad, not bad. Congratulations. It's all individual for a spark from a battery. It depends on many factors. There is a lot of interference around you and therefore you will not be able to squeeze out the maximum sensitivity. And now I have a question for you, is there an oscillator involved in this video fragment?
