I haven't listened to AM at night lately but that has been true for me. I've read that people could pick up KMOX in St. Louis like it was a local station west of Charlotte.Don't know about the gospel station but last week when they were switching morning patterns I heard KFAB on 1110 as clear as a bell.
There are times at night when you can actually pick up WTAM on 1100 out of Cleveland and they sound louder then WBT.
