I noticed a couple things and have some questions and thoughts for you.
what is the frequency your designing for? 3Mhz?
the secondary being wound with 2 parallel wires will have increased inter-turn capacitance.

is the primary a flat coil in cross section?

early on there was a x-cell spreadsheet put out that I heavily modified and shared a couple times, if you have one version of it have you checked the mass & surface area of the coils?

the latest version I have I've included capacitance, inductance, reactance etc on the coils. that helped in getting my coil set parameters close to what I figured would work and the best available based on wire gauge.

It's been awhile since I looked over my build and the calculations. very frustrated that once I got the o-scope the sig gen crapped out.
