Update: Some progress, but I'm still off the arc big time. I can confirm the pole's still vertical. The dish doesn't appear to be bent, but I haven't done a formal string test yet (hard to do when you're just one person).
Basically, I used a different receiver to blind scan and drive the actuator. I tried for 91W. I adjusted the position of the dish on the pole, but it still required driving the actuator eastward by quite a bit... probably around 10 degrees, similar to what I had tried before right after the storm and before I tried to swing the dish around (when I got NASA TV on 127W and Classical Arts on 101W by driving it east some distance, in order to get it at the right height in the sky). So, yes, I have it peaked on 91W and reset the actuator position here for now (just for 91W).
But unfortunately, I am only getting signals on 91W. I must be intersecting the arc instead of following it. Can't get any other signals by driving the dish with the actuator, even just a few positions away. Nothing on 101W, even when I try to drive it eastward. My thought is that if I were on the arc, all that would be necessary is to drive the actuator east or west, find the satellites, and reset the positions.
My longitude is around 83W. The 87W and 89W programmed positions go well west of 91W. I tried driving it to 91W then bumping it east (I'm assuming the 4:2:2 CBS feeds are still on 89W), but didn't have any readings. In observing the dish, it appears the dish is just slightly off of the "0" South position, westward a few degrees, ie -- probably where 85W should be. See attachment
In my mind, I'm probably too far west, and need to spin the dish eastward. However, if I do that and attempt to drive the dish with the actuator to 91W, then the LNBF will be looking too low (did that already when searching for 91W. Only had the Word Network at 40% and no other channels). Which once again makes me think evil thoughts about elevation/declination settings. It just doesn't seem possible, but here we are...
Thanks for any thoughts!
