Almost finished mine, I deviated from the plan a bit. I tried to add a lot of detail in my post. The latest 3.1 version is excellent IMO
I’ll try and make a wiki soon. I plan on using the dish I currently have setup on GOES with the rotator once I have a cover made for it, which will be soon.
Let me know if you have any questions about the rotator, I can’t speak about the helical.
