so, after a couple hours of trying to aim my dish(replaced a broken dish) i gave up from frustration from not finding a signal. I've never had such a difficult time. I was sitting on my couch listening to the hum of the receiver & trying to calm down before i broke someting. then all the sudden beeeeeep! 75% signal. so i sat there for a minute or two then huuuummmmm no signal again. a bit later beep, 75% signal again. this just continues so I have no chance of dialing in the rest of my sats. I have clear LOS. I replaced the cables too. Any ideas? is it a bad switch? My setup is vip612 with a turbohd dish with a second dish pionted at 129 because i never could find 121. Just to clarify I replaced the second dish because of signal loss freezing. I hope this is enough info.
