Did you mean HR20...H20 is the non-DVR version. Since you refer to the 0x10b upgrade, you must have meant the HR20. The absence of drop-offs may indicate it's doing a better job of handling multi-path. That's good news.sansabar said:I moved up from an H10 where I was using an OTA to receive the local HD channels. They were coming in (signal strength in the 90s) but would have lots of drop offs. Since the x10B upgrade to the H20 has allowed me to once again bring in the locals via OTA, I can honestly say that the drop-offs are almost non-existant. Hope it's something that lasts.
