[CQ-Contest] Vector Control Systems VBI-360

[Bob Naumann - W5OV]

Sadly, 

The company that made the VBI-360 rotor indicator is out of business.

Does anyone know where the knowledge went that produced these things?

They're the Great Circle map in a frame with LEDs around the circumference
of the circle that "graphically" represents your antenna direction/pattern
on the display.

Any help??
