I recently installed a Samsung 303W in my motorhome. The antenna set up is a King-Dome 9702. I also have an older Samsung SIR-70 for the rear TV. Everything seems to work OK but one exception, and that is the Guide gets lost on the 303W after about 3 days. I can cut the power on it and the Guide reloads OK but the problem repeats in another 3 days. I am sure I am NOT having any power problems. I did/do notice that the signal strength on the SIR-70 is in the Ninties but the only in the mid to high Sixties on the 303W. Any ideas on the problem guide??? Any ideas on the signal strength differences (the 9702 King-Dome has dual LNB's)? Is there a way through the menu's of the 303W to force reloading the guide (I don't like the powering up/down)????
