What kind of signal are you getting and are you aiming at 72W or 137W?
I have not aimed the dish yet, as I still have a couple of minor details to work out with the mount and pallet. Hopefully, I will be able to get a signal within the next couple of days. When I do acquire NASA, I will be aiming at the 72W mux.
This morning, I decided to go ahead and add washers as Corrado had done with his Fortec. I had a large stockpile of suitable 1/4" washers that were to be used on the 7.5' Perfect 10, so I used them on the SD180G (I'll buy more for the Perfect 10). I also flipped the ring clamps on the dish, as per Wrdavis' suggestion. I am very pleased with the results. Lastly, I attached the feed supports, scalar, and Eagle Aspen B1STACK to the dish. Except for some final touches, the assembly of the SD180G is now complete. I will include pictures of this morning's work and the preliminary testing in a future post.
