[BC] FCC part 73

[Jeff Glass]

Hello:

Is there a specific rule in part 73 that describes how to handle calculations and significant figures?

The specific part I'm interested in has to do with the calculations regarding AM channel allocations, interference, signal contours, departure angles, 50% and 10% groundwave, etc. My answers are not quite "right on" when I do the example calculations in the rules.

I'm applying the normal math rules when dealing with significant figures, which helps, but the FCC and I differ. They are apparently taking other things into consideration.
