As said, do not turn the reciever off unless you want the Tailgater to go through the whole process again. And yes, it can take several attempts on occasion, but if you have an unobstructed view of the birds it should not take 5 or 6 attempts, unless there is a problem.
I would double-check the connection, make sure you have as short a cable as possible (50-feet minimum) and that there are NO junctions or splitters in between. In my experience, when the Tailgater takes several attempts to find the birds it is suffering from low power through the coax.
I routinely run my Tailgater on 150-feet of coax. At that cable length it can take several attempts to find the birds. At 100-feet it requires a re-do considerably fewer occasions. I have found that every now and then the mechanism seems to get stuck, and simply jiggling the dome gets it moving again.
All in all I am very satisfied with my Tailgater and so far have no desire to upgrade to the newer, bigger Pathway X2. I suspect that the OP's issues have to do with very minor obstructions that happen to be blocking one or more of the three sats required for full service.
