Hi Hans
Thanks for the thorough reply. I tried squeezing the turns but could not get the response to match the expected. I think your point about loose turns is a good one although I did try to make the windings as tight as I could.

So it does sound like their is a toroid issue. Not with the toroids themselves but with the calculations.

I will have to get myself an LCR meter for Christmas.
