I found out to that my dish is a Eastern arc. I also change my service address so my locals can come out of Nashville.
If you want help it works best if you give us the most information you can up front. Don't make us beat it out of you one item at time. If we ask a question, answer it as accurately as you feel comfortable. Zip codes are pretty safe unless your home has its own Zip code.
Western Kentucky should be an easy shot from the Nashville spotbeam so I'm guessing the dish isn't aimed right. Echostar 16 SP09 hits just about dead center of the Tennessee and unless you're up near Evansville, Axe Lake or Blue Basin it should be fairly strong. The satellite information is 61.5W transponder 13 so if you're seeing a relatively low signal there, that's your problem.
Again, if you don't give us much to go on, you don't get much in the way of answer. Zip codes are really helpful as I said previously. After all, half of Kentucky is "west" and I'm guessing there are a number of hunting clubs in the west half of the state.
If my information is correct, Nashville is available on both arcs so it is a good thing that you specified that you have an Eastern Arc setup.
