I also have a 24" dish dedicated to 129 and have the old point dish screen still. Here are my numbers as of 7:15 Monday morning:
TP1: Appears stable between 51-55, sitting at 53 most of the time.
TP2: Stable at around 53-55, peaks occasionally at 56.
TP4: A nice, strong 70.
TP5: Stable at 57, with occasional dips to 55-56.
TP6: Fairly stable at 53, fluctuating often betwen 51-52.
TP7: Stable at 57, with occasional dips to 56 and peaks at 58.
TP8: Not locked, with a ss of between 64-65.
TP9: Stable at 68 with occasional peaks at 69.
TP10: Stable at 66 with occasional swings between 64-67.
TP11: Fluctuates between 53-55. Never sits long at one ss.
TP12: Stable at 66, with occasional peaks at 67.
TP13: Stable at 68, with occasional peaks at 69.
TP16: Flucuates between 51-54.
TP17: Stable at 52, with occasional drops to 50.
TP18: 0 signal, not locked.
TP21: Fluctuates between 48-50. Occasionally loses lock.
TP22: Fluctuates between 48-50. Lock seems stable, but low.
TP23: Stable at 53 with occasional drops to 52.
TP27: Stable at 53, with occasional drops to 52.
TP30: Stable at 64, with occasional drops between 62-63.
TP31: Stable at 69, fluctuating between 68-7 occasionally.
TP32: Barely holding lock at 45, occasionally peaking at 48.
Over the course of an hour, these numbers will drop to the low 50s (or lose lock in the mid 40s) and, in some cases, peak as high as 84 on TP4.
That's life with 129 in the Pacific Northwest, even with a 24" dish for it...
