Who or what determines “good engineering and good amateur practice,” as applied to the operation of an amateur station in all respects not covered by the Part 97 rules?

Answer: A. The FCC

The FCC decides what counts as good engineering and good amateur practice for anything not spelled out in Part 97. It is the FCC's standard, not the control operator's own opinion.
