Thank Ram I will have a good look at that. Do you know if it can be used with a small coil of about 200mm? 

Regards Xavier



hello xavier, for me maybe it will be used for small coil with little modification on transmitter coz it's deeper 120hz . for this time i'm planning to construct just in matrix board for testing. also pls verify the veracity of this schematic for w/c the info that it beats the dp in performance.

regards, ram.

Hi Ram

I see that the one you posted has an auto tune in fact it's not at all the same schematic as the one that fff posted so now I'm starting to worry as this is going to cause confusion. Why don't you guys post a working, tested, and complete schematic so that the guys that want to build it can do so without having to worry if it's going to work or not? you will then be able to tell them where they have gone wrong and assist the beginner but like this no one can make heads or tails out of the thing. Which of the two schematics is the correct one?

All the best to you and I hope that we will be able to shed some light on the subject.
Regards Xavier

My old schemes  work also. SBG-PI is new scheme to create digital signals and give a strobe receiver. More stable operation.

yes i am also confused when i see the schematic posted by fff w/c my schematic differs but same bulgarian pi. the schematic i posted is working when i downloaded it the builder said it's working well and beats the dp performance, so i want to build it for confirmation of the veracity of the info that it beats the dp. also i checked the original schematic w/c is from the author and the re drawn have no mistakes and the pcb. so, i have to build it in matrix board for easy wiring just for experiments to find out if it works perfectly.for now i'm gathering some parts. 

regards, ram,

Good one Ram I will see what I can do on my side if you build the one that you posted then I will start to gather the parts for the one that fff posted that way we could have both of them build and compare their performances.
