I have a problem that started about a week ago. Every morning it seems that we keep getting the "Acquiring Satelite Signal" message and it doesn't acquire the signal. I have to pull out the programming card (sometimes a number of times) to get it to reset and then acquire the signal. This is only happening on my 6000 receiver. I have a 6000, a 2700 and a 508 with a SW-21 and two dishes. The 6000 is the only receiver using the SW21. This seems to mostly happen in the morning - mosture? We did get a lot of rain a week ago from Ivan. Should I switch receivers to see if it is the receiver (8vsb card?)? Or should I silicone the plugs on the SW21? I have run the switch test and once it failed but has passed other times. What do you guys who have a lot of install experience think? Thanks for your anticipated help.
