I hear them regularly here in Pittsburgh, not strong all the time, but when they are it's a good listenable signal many times.
They were really pro AM stereo for a while, with airchecks on a Meduci tuner, playing stereo rock shows and even trying quadraphonic recordings, which I think was on host Buzz Burbank's show. I think they gave up AM stereo though, I don't remember why, but there was a statement about it in the press at the time.
