When my dish was pointed at a satellite, the compass would be affected by the signal. From my location, my Azimuth was supposed to be 210 to hook IA-5. I am new to this part of the country, so my sense of direction is lacking. Every time I used the compass, I hooked satellites that were difficult to identify on lyngsat.com . It turns out they were all East of my target. I got the sense that there was a problem when I realized that for one of these aims I was pointed at a tree top in my yard, for another I was pointed at a different tree in my neighbor's yard. IA-5 wound up being in line with the peak of my neighbor's roof, about
45 degrees 
away from my initial aim.
How my problem was solved:
I got out the site map of my house (from among my home purchase documents) which had a compass indicator for North. I lined up the line representing the South wall of my house in the drawing with the physical south wall of the house and checked the compass. Doing this inside my house, it seemed apparent that the compass was nearly correct with the drawing, but 210 was pointing somewhere along my neighbor's roofline. When I went to the roof, I discovered that the closer I got to the dish, the compass would turn counter clockwise. I held the compass up at my neck height and estimated where it pointed relative to my neighbor's roofline and aimed the dish. I then tilted it up and down until I got a signal. Satellite HOOKED! But, after doing the scan on the receiver, I found stations that are only on AMC 3 (14 degrees EAST of where IA-5 is supposed to be!) Up on the roof again, I held the compass at neck level, and added 14 degrees. Noticed that the peak of my neighbor's roof was almost exactly in line with this Azimuth. Lined up the dish, tilted it up and down to find the signal, fine tuned it with the SF-10, and FINALLY HOOKED IA-5! Did the scan, and found 118 stations - OVER 20 in ARABIC!
Thanks to all who posted to this thread, it was helpful to know that looking at the TPs on the lyngsat.com website and comparing it with those found on Blind Scan was the right strategy to identify which satellite I was hooking. This process was time consuming, but eventually worked. In the hopes that I can help someone else deal with a similar issue, I will copy my solution to a new thread entitled Compass Problem SOLVED!
