According to dishpointer > you are at 73.9W where you are in WV, SO, the satellite you are finding now is closest to being your 'true south' satellite. That is, the satellite that is nearest due south from where you have your dish, and therefore will be at the highest elevation for your dish. (AMC-6). You want turn your dish west on the pole, mark the starting point with a pencil so you'll know where you were, loosen bolts on the dish mount and twist the dish to the west. compass reading 190 to find Galaxy19.
Elevation for that satellite should be near 42.8 degrees. It won't take a lot of movement of the dish on the pole to change satellites, like 1/8" at a time. It's tedious without a meter but it can be done. Have the receiver and a tv out by your dish to make it much much easier.
edited to add : Choose "ALL" on the polarity setting for your Nano, and Blind search or ALL ( picking FTA just scans the Non-scrambled channels). Blind search should find any channels it finds signals for .
