Marty,
65 is low.
Remember, there are (I think) 32 transponders, and you have to get a good signal on all of them.
There are 32 "antennas" on the satalite, and you have to get a good (90+) on all 32 antennas.
Also, if wind knocks your sat out, your dish or something is loose. That dish should be rock solid.
Now while signal strength is important signal QUALITY is either YES or NO. You will not notice a "better" picture or "Better" sound with a 90 vs a 65 signal strength. Just letting you know that when you were watching TV, you were not missing out on anything.
Also, if "rain fade" affects you a lot, you can purchase an optional 24 or 30 inch dish. The bigger the dish, the more clouds and rain it takes to block the signal. People in seattle I hear use the larger dishes because of all the rain.
Also, just a general note, put the dish were it is easy for you to access. The satalite is 22,500 miles in space, putting the dish 2 feet or 20 feet off the ground makes no difference in the signal!
