I spent some time yesterday listening to WCBS-AM, to get some last listening in before its demised. The programming was basically a retrospective look on the history of the station, going back to the 1930s. Sad to see it go—when I was living in North Carolina, I'd sometimes even listen to it at night. The range was almost 700 km, but it was a 50 kilowatt clear channel station, so it (often) worked.
