Asunto: [amsat-bb] Adjusting true north for azimuth rotator.

I am planning to install my G5400 rotator inside a tower having a welded 
rotator shelf. The tower is not installed yet and will have one face 
against the side of my house which is positioned about 28 degrees 
northeast (Per Google Earth).

I assume when I drill the rotator shelf, I can adjust for the gross 28 
degree offset of the tower. However how important is it to do this at 
all? Does the rotator have to be installed exactly toward true north or 
can I make up the difference when clamping down the antenna mast 
assuming the antenna is oriented true north?  Note I will be using a 
Trakbox and need the ADC to center on true north.

Secondly does anyone know if the ruler function in Google Earth points 
true north? It seems pretty handy that a fire plug in front of a 
neighbors house is at about north point.
