Hello, I found that number of turns for L32 has to be 47 instead of 52 to reach the 330 uH value. I used an HF generator with a 100k resistor in serie to feed the coil in parallel with a 4700pF/5% capacitor. Does somebody confirm this behavior or am I doing something wrong in the measurement. BTW, other coils are around their values using the same method. -- 73 Gérard F6FGZ
