I have noticed a significant drop in signal strenght on 119 Spot 3. The signal drops out to less than 45 (on the "old" signal meter on my 3900) at around 245 pm EDT. It comes back up to a lockable signal at around 745 pm EDT.

AT the same time the signal on spots 5 and 7 are increased to over 100 where as before fall they only came in at around 75.

What gives. This happens every fall and so far I have gotten no valid reason. Do the birds wobble more in the fall winter as oposed to spring summer.

My dish has an unobstructed view to the sky. Any tech people know why this happens?
