Last Thursday I succesfully re-aligned my AU-9 to get better signal strength on 99c. It was strange enough that I thought I'd share the experience.
Here is a sample of my signal strengths before re-alignement:
99c: Transponders 1 and 2: 47 and 66
99s: Trasnponders 2 and 4: 95 and 96
101: Transponders 17 and 18: 81 and 98
Notice that 99s and 101 are fine, but 99c is very low.
I tweaked the re-alignment by having my wife walkie talkie my signal strength readings off an HR21-700. After tweaking, I got:
99c: Transponders 1 and 2: 89 and 87
99s: Trasnponders 2 and 4: 98 and 99
101: Transponders 17 and 18: 81 and 99
I tried tweeking each of azimuth, elevation, and tilt. Only azimuth was off. But it was off by almost a full 2 rotations of the dithering adjustment. (I ended up pointing just a little more to the West.)
So the signal strength on each of the satellites improved a little. But 99c improved a lot. Does that imply that the 99c satellite (D11) is actually a little bit further West than the 99s satellite (Spaceway)?
