WGN has OTR on Saturday and Sunday late nights around the midnight hour.
It comes in great on my radio in NC.
The only drawback is, they stretch a half hour episode into an hour of radio time with a some very long breaks.
The host Carl Amari is apparently a big shot in radio drama. He produces new Twilight Zone radio episodes which I hear on weekends on a channel in the 1500s. He has also made a New Testament audio tape with big stars doing the reading. I hear ads for it.
