Variances of this problem have been on here before, but I want to hear other opinions on this problem. Some days after 3 pm, I lose all satellites suddenly. It varies as to the time of day and some days it doesn't happen at all, somedays it will happen twice or more. 622 does not reboot and only once in a while do I have to reboot to recover signal. I have a dish 500 pointed at 110/119 and a 30 inch pointed at 129. Signals are very strong normally. All of a sudden I get "searching for satellite" I have deleted weak ota stations as advised in another thread and pressing dvr button does not bring stations back. Lnb on 30 inch dish is new, other lnb not. System info shows no drift. The only weakness in my system is a 16 year old RG6 cable, it is buried underground however. Opinions?
