WFC design session v10: best candidate (Q=66.7, 99.1kHz)
Sweep — sweep choke turns/wire gauge to raise coil Q past 707 toward theoretical ceiling, testing if tank Q exceeds 65 while holding adopted cell geometry fixed
- Cell — 22.8mm rod in 29.5mm tube × 76.2mm, 1 cell(s) parallel → C = 1.29nF, water R = 88942Ω.
- Chokes — 2 × 0.001H (140 turns, AWG 18, 17m wire, AC R 0.6Ω each).
- At resonance f_r = 99.08kHz — Xl = 1245Ω, Xc = 1245Ω, tank Q = 66.7, coil Q = 1012.9.
- Cell voltage 801V from 12V drive (×66.7), series current 643.2mA.
- All constraints satisfied (current <1A, band, wire length).
- Score 0.724.
