[TowerTalk] Yaesu G-8000 DXA controller with G-450 rotor

[Herbert Schoenbohm]

It seems to be from the G-450 schematic that the rotor motor has two 
winding one for one direction and other direction and the other for the 
opposite direction and uses three wires to accomplish this feat. Very 
strange design indeed.
