Basically, my HR20 OTA reception is fine. I get all channels that I should get and their signal strengths appear to be accurate. The ones that never pixelate are near 100% and the problem child is in the 40% range - as expected. I do have one anomaly that I'm wondering if anyone can shed some light on. My 40% channel (channel 44.1) actually works very well most of the time. I'm using unamped rabbit ears and it's about 20 miles from me, no hills or obstructions. The curious one is that I get a signal strength of 85% consistently (both tuners) on a channel 8.1 that is 80 miles from me. The curious part is that despite the consistent 85% signal strength, all I ever get is "searching for signal" when I try to tune to it in the guide. How can get an excellent picture from a 40% signal and absolutely nothing from an 85% signal? I seem to recall reading that the HR20 signal strength meter isn't incredibly accurate but my readings on roughly 25 local channels seem to be consistent with my experiences while watching. It's only the one channel where the reading is wildly different from what I'm (not) seeing. Any ideas?
