Moons of Madness I need help please!

Hello, I’m STUCK at the part where I need to restore power to the dish. I got the power panels up & running but I cannot figure out how to get the dish to work. I’m able to set the parameters to 158.43 but I’m unable to get the power to stay at 85 percent. It stays at zero. It will go up to a certain percentage but as soon as I try & reset the pitch & yaw, it drops back to zero. I’m playing on PC, I use the A/D/S/W keys to navigate but I cannot progress past this point. What am I doing wrong?
