I remember as a kid, probably around 1985-1987, going to a baseball card store in Morton Grove on Waukegan Rd. I remember in the back of the store, there was a radio studio, usually the curtains were drawn and the room was dark, but sometimes something would be going on. But I have no idea what this was. Can anyone help? Who used this studio and for what purpose? The amount of time the studio was dark makes me think it was just for a weekly show maybe?
