Thanks to Jim for tracking down the 5.1 audio issues. Everything has been great since then.
What kind of antenna are you using? I've done systems from Columbia to Laurel and none have any issues picking up WDAM... as long as we point towards Petal or use a rotor.
If you are not using a rotor and pick up the coast stations fine, I doubt you will be able to get WDAM. For the most part, you will have to move the antenna to get acceptable signal on both...
