Points are then miles/kilometers per watt.
One could also fool with idea of the points being:
(distance * (PowerOtherStation + PowerMyStation) / 2)
Hmmm.... Good idea. But I'm thinking distance propogated by the signal, not
earth-surface distance. And you'd want to adjust for the effects of gravity
as the signal passes nearer the surface of the earth.
Huh? what gravitational effects do you have in mind? I know
gravitational fields can change space-time, and thereby the path of
electromagnetic radiation, but in what way would you have in mind, and
are you sure you want to start including relativistic effects?
And are you sure you want to account for the propagation paths? How do
you decide how many hops are involved? Short path or long path?
If all you really want to do is equalize the antenna questions, why not
use ERP rather than merely power?
So you would have the power out, - coax losses, +/- antenna gain; that
seems relatively fair doesn't it?
To keep it fair, I think we absolutely have to adjust for the attenuation of
the signal due to the directionality of the antenna. I should get more
points for a QRP QSO off the end of my dipole than you guys with beams get
for QSOs where you're aiming right at the station. Ditto for the receiving
antenna.
I think the modified formula using ERP on both ends would normalize for
this, wouldn't it?
I'll get started on the math unless one of you knows this off the top of
your head. We'll want to nail this down pretty quick so the logging programs
will have time to implement and test it.
