I have an old Echostar 3000 receiver that I have carried around for years in an RV. I use a single LNB dish for this set-up. I was just given a d/p 301 receiver. I have not activated it yet-wanted to see if it works! When I replace the old box with the new I do not get any signal in the strength bar-none. I could be wrong, but I believe that even a non-activated box would receive and show some signal indication. Am I right, which would make the 301 bad.
