I just did an upgrade on Tuesday from my 10-250 to the HR20-100S and the 5 LNB for my den. Downstairs I had the H20 in bedroom that I got when they first came out and a new H20 for the living room last week. After some signal issues and not being able to receive any local HD channels via the dish or OTA from the antennaes on the H20 in bedroom or den, I was able to receive HD local channels via the dish. T The interesting thing is that I have a inexpensive antennae hooked up to my HR20 that worked perfect, and actually better than the Terk I have in the bedroom for the H20. When I checked the OTA local stations (I keep hooked up for storms when dish goes out), the channels off of the OTA in the bedroom ( the dash 1 stations) came in perfect. The same channels on my new HR20 still will not receive and still show the 771 message. How can it be that one receiver will receive and the other not? I even tried moving the Terk to my HR20 and still no reception. The HR20 has the connection in back for the OTA so was thinking that it would work fine. Any ideas of what the issue could be? I find it strange that my old H20 works fine and the new HR20 won't pick up the OTA antennae signals.
