Interesting.... all of the TCS sets I've used, including my own have the
minimum inductance at the high number end, not zero. Also the external
loading coil is minimum L or bypass at position 6, not 0.
Always thought that was odd, but I adapted to it.:-)
(no I wasn't standing on my head when tuning them)
