I live in north east Mississippi. All local channels except 2 has great sound/volume. The best example I can come up with is; when watching WCBI or CW the volume on 30 on my tv sounds like 15 on all the other channels. Once I reach 35 on my LG LED it doesn't get any louder. I don't have this problem with any other channels. Can anyone tell me why the volume is so bad on those 2 channels?
