Bad economic times killed it, I think.
All these years later, I see even less interest / use than back in 2009.
On the forum, there have been a few threads where members have built up little PC boards with the servo control for V/H from LNB voltage, using a 1-chip micro controller to pulse the servo.
Search the forum, if ya like.
No one has linked the dish position to specific servo settings, a feature the V4000 might have accomplished.
Oh, and if you're looking for just a position controller, the best is still the Gbox v3000 (see my signature).
I might suggest we provide links to some of the follow-on projects, and then close this thread...
