Re: [TowerTalk] Take off angles, VOACAP, etcf.

In terms of the simple math and numbers, you are correct. But to USE 
the numbers to make a construction decision is where the other 
considerations come in.

If you use VOACAP running under "poor" station restrictions, you DO 
come up with different figures. Angles that a broadcaster would pick 
in a heartbeat are not allowed to surface without a penalty, and 
powers used preclude use of a weaker but more "reliable" mode with 
higher transmitted level by the broadcaster.
