As I mentioned earlier in the article, the value of C4 may vary depending on the workmanship of the board. For handmade boards is better to choose the value with experiments. Boards that i sell are machine made ​​and it's still difficult to achieve the required thickness of the coils when etching. Still is a chemical process dependent on many factors. For my card value of C4 with 3.3nF works much better than 8.2nF value as in calculations. Success. : arrow:
