Based on the translation I'm reading the 200 mW applied to elevations
from 5 degrees to 30 degrees, and for elevations above 30 degress the
limit is 125 mW. I'm not expeienced with regulations that vary with the
elevation angle. Why should we use 200 mW instead of 125 mW, which is
allowed for any elevation?

The translation of OD-86a I'm reading says "use mostly indoors." Is that
an accurate translation? How does this compare to the language from
OD-86? I'm a little unsure how to interpret it.

Thanks,
Seth
