It took me 3 hours but I rolled two perfect 126 turn Toroid inductors. These will be two halves of the two transformers in a Tandem Match Circuit (Directional Coupler). Should have infinitesimal insertion loss

@ab3xu Sadly the final design (just finished a few seconds ago) had its self resonance kick in at too low a frequency. Probably going to have to go back to a modest 20 turn setup.
