Maybe I am missing something here or maybe you have one hell of an antenna
system - but from San Francisco - +/- 15 degrees from the center of VK
covers the whole continent - and I think the 3 db beamwidth on most HF yagis
is lot wider then that.
Maybe you used a bad example - the CONTINENT of Africa is a lot larger - but
I think the file has headings for the different countries on THAT continent,
does it not? So for a typical tri-bander, even most mono-banders, it isn't a
problem, is it? Like I said - maybe I am missing something.

Bob, it is my understanding that WL only gives beam headings for the center
of each country. Obviously, from VE, a single beam heading for VE and W
doesn't make much sense, but now you know why. You may think that the beam
headings to countries in the rest of the world work ok, but they too are
only
to a single location in each country. Look at VK for example, and you will
see that you have only one beam heading for the huge land mass of VK.
WL would need exact lat/long data for each station in order to calculate a
correct azimuth and, of course, that is not provided in WL.
