Okay, I had both 811 receivers before leaving for the weekend on Friday. When I returned home Sunday night both worked fine. When my wife got up this morning (Monday) the same problem as before. I get Error message 002 and the receiver gets channel 229 iSHOP, but apparently no other satellite channels. The customer service employee runs me through the usual drill, but it is no help. When this happened last week I swapped locations and it seemed to have fixed the problem, albeit temporarily. I am thinking of getting some RG-6 and running the cable to the room where the other 811 is working fine to see if this corrects the probelm, rather than moving it. It is a nuisance to move my 811 receivers. Does anybody have any thoughts on what is going on here? When the check switch test is run it seems as if it is only seeing one satellite. The other interesting symptom is, like before, if I let to run its course on the "Acquiring Satellite Signal" routine it will eventually get to the point that it is going to download the program guide, but it will not download it.
