It's been a long time... our HR34 has become unstable, requiring multiple RBRs in a week. Also, sometime recently, the AM21 has started getting 771 errors, and now fails completely. The OTA signal from the antenna directly into the TV is fine. So, time to call in the upgrade that we're due on our service plan; is the HR54 what we'd likely get? I read here that the LCC isn't great, but the AM21 isn't doing anything for us right now, so anything is better. Our main use case for the AM21 is to get local networks from the Hartford DMA; we live in Western CT and are in the NYC DMA, which gets us the "wrong" local news, weather, and political coverage.
