I still say Hawaii is West of my location on a flat earth on a spheroid earth it is Southwest I point my antenna Southwest I can't contact Hawaii I have to point my antenna West. Those are the facts and I'm sticking to them. This kind of evidence doesn't lie and is irrefutable.
Again, I think you are picturing this wrong.
What "flat earth" has Hawaii due West of you? The Az map from your link? Again, that program creates a map based on a globe which positions things in straight lines from you based on a given direction you face
from your position according to a compass.
On the Earth, when you are on the equator and face due West or East according to the magnetic compass, you are basically looking down the latidude line. It stretches out due East and West from your position. However, when you are North of the equator and you face due West according to the compass you are facing a direction directly perpendicular to a North magnetic compass heading. This does not, in fact, face along the latidude line. Because the latitude lines circle the Earth at a given distance from the poles, the latitude lines would not run in a straight line
from a given point when facing due East or West, except on the equator. And so, when you are facing West above the equator a straight line on a map in the direction you are facing would lead to a point South-West of your position.
It's a bit hard to grasp. Which is precisely the reason for the map generator in the link you provided. You give it your position, and it generates a map which shows what a straight line would cross in any given heading from your position. This allows radio operators (etc.) to easily gauge what direction to point an antenna from their location in order to be directly pointing at any other location on Earth.
