When I set transponders to a certain number I can get 62% strength on hd. If I check later because the picture isn't as sharp the transponder number has moved to another number which only gives me about 43% signal strength. The lower numbers it always says transponder in the setup page.When I change the transponder to a number where I get 62% signal where it says transponder in setup page it then switches to spotbeam. I hope this makes sense. Anyone know why the transponder number moves or is it suppose to? Is there a way to lock it in when the signal is 62%. Also I tweeked the dish and had 62% when done on hd.
