After more than 16 years with Dish, I finally upgraded last week to HD pointed at the eastern arc from Pennsylvania. A queston on signal strength, which seems to be lacking current information on these forums and elsewhere on the web. My signals seem to be very good on everything but 61.5 transponder 16, which is only 36. All others on 61.5 and 72 range from upper 40s to lower 60s except the spotbeams I don't get, which are 0. Typical for 16 to read so low?
