Minneapolis, MN with a fairly new 1000.4 installation on a clear day...
61.5 TP21 57
72.7 TP21 42
77 TP21 55
I have not had any problems loosing programming but have checked 72.7 during rain and heavy clouds a few times and watched it easily dipping into the teens. With an HD package I imagine I am mostly watching 61.5 but I am a bit concerned about my low 72.7 numbers. If there are any other Twin Cities people interested my 61.5 spotbeam is high 30's.
