My mother-in-law called me today and told me that her DISH 500 is only getting signals from one satellite. She said that she went through DISH Technical Support who had her try a few things, but it is still only getting signals from one satellite. Anyway, I have a DISH 301 and I am wondering if it would be worthwhile to try swapping those receivers. I think that it is time for them to consider upgrading to a newer receiver, but if this would get them by for a while longer it may be helpful.
