Hello, In light of the upcoming changes by DTV, I've been surfing around looking for the same answers as everyone else. As my current HD STB, a Tosh DST-3k, is starting to go out, I decided to try one of the new H20s. I have a UHF only antnenna and pre-amp. I went through the setup and was able to see signal strength for the satellite transceivers. However, I was unable to see signal strength for any OTA channels. This is after trying two H20 boxes, and spending time on the phone with DTV's Tier 2 support. I'm wondering if I need to activate the box just for it to see signal strength for the OTA cahnnels, even thouhg it's able to show strength for the satellite. DTV says I shouldn't have to activate the receiver, but what else can it be? When I connect the cable back to the old STB, the locals come up fine. Any ideas?
