Hi All I have used these cores and noticed no difference between them and a continuous type core. I put the two core halves together tightly and used the same number of turns as used on the continuous core, maybe I was lucky. What does Jim call a gap? If they are tight together is that considered a gap? Must the core be totally continuous? de Mal/G3KEV
