That might work, but again this evening the CPEs won't stay up long enough to log in and do anything. I did climb up to the antenna on the worst offender from last night. It is shooting right through a very pretty yellow and orange tree. October is a pain for 900 around here. My theory is the color in the leaves is from the metals that get left behind. Thus we have a bunch or mirrors making all sorts of goofy signal patterns. It is probably worse in the late afternoon/early because everything is warmer. It settled down on its own sometime around 10:00PM yesterday.
