[TowerTalk] Interesting Rotator Controller for Sale

[Ken K6MR]

That’s the original HyGain RotoBrake controller.  A little tough to interface directly to anything else because it uses a 400 cycle selsyn with a 5:1 gear train.  Very nice display though.  Of course now it’s way easier to get a display like that on a computer screen that is centered on your QTH.  This display is centered (if I remember right) on central US).
