I was reminded by Mike's question of one of my own, I've been trying to use
YT to assess the optimal height for a new tower, given my terrain. Does
anyone know how to get a file output from YT of gain vs. elevation angle?
What I want to do is essentially integrate the product of gain and
probability over elevation angle to obtain an "expected value" of gain for
a particular tower height/direction/frequency combination. YT provides a
graphical output, but it would be most helpful if the data points were
written to a file. Maybe someone on the reflector knows how to do this or
knows of another program that would solve the problem.

Subject: [TowerTalk] YT and approach angles
I've been playing with YT for the past couple of nights, and would like
to know more about the approach angle information used. If I understand
it correctly, somewhere outside of YT a lot of work was done to create a
comprehensive picture of the distribution of the relative occurrences of
signals at different approach angles on a specific band, in a specific
location, throughout the day/year/sunspot cycle. What I'd like to know
is what changes occur to the distribution of approach angles during the
sunspot cycle and during the day.
