When ever I go into the sat dish menu to check a transponder it is defaulted to 105 sat - which I do not have. I have a dish 1000.2 that looks at 119/110/129/61.5. I have to manually turn the sat in the menu to the proper one because it no longer will go there by itself. I consider this the reason for the lost locks. They broke something in with the 401 software that has caused this lost locks problem.
The first time I went to point dish 6-1-1 my system froze and I had to do a soft reboot. When it recovered it worked fine and i only saw the sattelites I should get. Never saw 105.
