[QUOTE="jncsk8r, post: 798303, member: 387717"] Eureka! So, after speaking to AFU Europe they directed me to AFN Afghanistan who sent me an aiming document that had everything exactly the way I had it, to the T. However, some where during all the up down, left right confusion I missed matching proper LNB skew with proper Az and Elv. After receiving the document i immediately went to my dish, rotated the LNB to the 4 o’clock position and EUREKA! NASCAR comes on behind me. Signal lock, but no quality. Then it started raining so I had to pull down all my equipment and didn’t get to fine tune. Anyway, the hardest part is behind me I’m happy to report. Below is the documentation sent to me from AFN Afghanistan: [B]Eurobird Sighting Instructions[/B] The Azimuth is 252 and the elevation is 43 if the dish is inverted (if not inverted it is 13). When you are standing in front of the dish looking directly at it, make sure the connecter where you plug into the lnb is at the 4 o'clock position. If you can bring the decoder and small tv out right next to the dish and connect it directly to the dish while you are aligning it, this will help. Go to the menu and then preset lnb and this will allow you to look at the signal levels and whether you get a lock while aligning the dish. Once you get to 252 and 43 put a small tick mark on the dish as a reference point, barely go to the left and then up and down slowly on the elevation arm, go to the left and up and down on the elevation arm, etc....until you get about an inch from the original spot. If you do not get a lock, go back to 252 and 43 and repeat to the right. This should help you to get a lock.
