In pre-Internet times, I had no way of hearing my college radio station when I went home for the Summer. I sometimes wondered who was on the air and what music they were playing. Sometimes, I also wondered if the station had signed on for the day. It wouldn't have been out of the question that someone would have been reading the sign-on, "KCOU Columbia now begins its broadcast day...," at 11 a.m., 1 p.m., or even 4 p.m.
