Hello, Need your help. For a long time can't get working FCP for my Inverted L. I'm looking for some way to check quality of my homemade isolation transformer. I'm connect primary to 50 Ohm dummy loa

William, Thanks for idea. Are you absolutely right - 5uH is too small for 160m. Looks like I have a wrong toroid. After playing with amidon toroid calculator, I found that 20 turns on T300 will give
