I proposed 100 kW days, which is legal under "Rio" rules for Class As,
plus whatever night power which would give them at least 362.10 mV/m/kW
at 1 km.
Lessee ... that would be about 60 kW nights.
However, I also pointed out that 195 degrees was only nine measly tower
sections taller than that atrocity which was proposed.
Which would you accept:
1) 100/60 kW ND-U into 155 degrees, with the likelihood of bad fading
during critical hours, plus an unknown effect on the Class I-B in Canada,
plus a few micropower Class Bs in the U.S., and being grandfathered at
that level, or
2) the present, and "historical" power, 50 kW ND-U, into 195 degrees?
And the answer is ...
... behind Door Two!
