I created this video to explain how to fix the most common problems what many people ask me about when starting with Altium Designer. I hope it helps.

Do you know what I changed to improve the signals in the picture? What do you think?

Do you know how a chip is designed? Did you know there is a way to manufacture your own chip … and for free?

Do you know how a PCB antenna works? Is it the same as what John is explaining in the video?

What do you think, is there a difference if you place PWR and GND planes close to the component layer vs. when you place the planes far away? I was very surprised …

Do you pour copper on your signal layers or not? Thank you very much Rick Hartley.
