Who can help me with my board

[lxs17757414132]

My PCB board, I hope to improve it, but I am a beginner. Can someone help me draw a schematic

I made the following modifications

What is the name of the detector? From the IC's it could be a mix out of PI Polones with VCO.

what CAD soft you use? i can not open your .pcb file.

Altium Designer Using this or jlc EAD

Opened the circuit diagram

I see that the intention is to adapt a VCO to the Polish pi circuit and for that it is using the VCO of the 4046 but as you can see there are a lot of pins left it would not be more interesting to use a dedicated Ci with just VCO I would use the LM566.

I also feel that it is astonishingly similar to PI Polones

Proscan was with it.

I used 2x2m square coil to find a shovel in 2m air

Hi Emersonpaz

One of the main reasons for using a CD4046 instead of an LM566 is simply availability and price. The LM566 costs at least 10 to 15 times more than a CD4046. Both have IC's have a good VCO built in.

[Emersonpaz]

You're right, friend, I hadn't noticed the price difference between the Ci's.

Carl had open a topic when he choiced what chip is best for VCO. you have to remember.
