I must first admit to being somewhat obsessive compulsive about signal strength. I am on western arc satellite #110, 119, 129. Within the last two to three days signal strength on # 110 has increased nearly 10 points from a running average of 67-68 to an average of 77. Signal strength on 119 and 129 have remained at long term readings, no change. 110 has consistently read below signal strength readings for 119, What gives?
