[na-user] Beam headings

[David A. Pruett]

We had very few complaints about beam headings until I implemented a new
algorithm passed along by N6TR that included distance calculations.  Tree
and I wanted to be in agreement for the W1BB contest.

To be honest, I have no idea how the algorithm works - it is full of trig
functions, identities, etc.

If someone will test their cases and provide a list of problem situations,
I'll take a look at fixing the code.  I will need:

1. Your latitude and longitude exactly as entered into NA.

2. The problem country.

3. The latitude and longitude of the problem country as defined in your
COUNTRY.DAT file.

#3 might not be necessary, since this data does not change regularly,
however it ensures that we don't have a bad country file causing the
problem.

73,
