Hi Bob,

Why would the winding of toroids be a problem only for QRP Labs filter kits and not for *any* project that has toroids to wind?

  No, I didn't examine Q. I took the default values. I was focused on inductance values in the model to try to determine from my measured S21 gain trace why one of my filters didn't perform well. For the QRP Labs filter kits winding torroids appears to be a source of problems.
