Back when I used to listen to it (60's through mid-70's) it had enough of a
variety of programming to make it worth using stereo, and none was
available. But who needs stereo on a talk station? It's a waste.

Why is it a waste? Spots are stereo. Jingles are stereo. Bumpers are
stereo and a creative programmer or engineer could easily make local
interviews stereo by panning each person slightly off center.

If you take most syndicated programming, you're out of luck.
