My recent return to serious AM DXing has only proven that I
still have a
lot to learn.
For instance, I spent the past day reading detailed reprints
from the
NRC and IRCA publications involving Local Sunrise and Sunset
DXing,
including a review of maps and calculations. Complicating
the issue are
FCC rules changes which have changed the types of stations
and their
authorizations.
At the moment, I'm looking for software or a web based
application that
would provide the following information without having to do
a lot of
manual calculations:
1.) Gray line map showing also the tilt of the earth between
solstice
and equinox. In other words, a map that provides a real time
view of the
earth as it really is today. Not a simplistic representation
that does
not change with the seasons.
2.) The ability to select any two points on earth and see if
they are in
darkness or light.
3.) Domestically, I'd like a map that shows which areas are
operating
under sunrise or sunset authorizations. In other words, one
that will do
the calculations for me.
Does such a tool exist?
