I've read very little about those dishes, and never seen one.
Always wondered exactly how the spinning related to the declination.
Thanks, B.J. for the description.
Not at all what I expected. ...
One other issue I ran into with the spinclination was that, when I looked at the thing (there weren't any instructions with it for some reason, even though I bought it new), was that I realized that turning the dish clockwise or counter-clockwise would give the same declination angles, so I thought that it didn't matter which way I went, and I ended up rotating my dish counter-clockwise looking from the front. The problem with this was that when I came to the end of the limits of the motor drive when approaching my western horizon, the dish was rotated so that it was aiming back to the east a few degrees, and I couldn't get the dish to reach a couple western sats that I actually could see. So I had to do it all over, and rotate it the other way, clockwise, so that the dish looked slightly to the west, and then I could reach the western sats. This didn't make a whole lot of sense to me because with an 8 degree bend in the pipe coming out of the back of the dish, when I rotated to give me my 6 deg declination, it would only be tilted about 2 deg along the arc, so it didn't seem likely that I wouldn't be able to reach the western horizon only because of 2 degrees, but apparently they had it set up with a bit more travel in one direction than the other so that you were supposed to only rotate it in one direction. Now that I have the thing apart, I should look at that again and see if that was really the case, but that's the only logical reason I could think of for why rotating one direction would keep me from getting to a couple western sats.
