[time-nuts] 60kHz Loop antenna

The coil with 50T and 5 foot diameter is 11.5mH.  It would take about 220pf
of self capacitance to make it resonate at 100KHz.

Anyway, if the capacitance is too much, it's all in the way you splice the
ends together in the conduit box.  If you want, you can make the loop a single
turn with 50 parallel conductors.
