Yeah, another rip from SWLing links:
https://www.wvxu.org/post/wlw-am-begins-100th-year-air#stream/0A nice read on the history of WLW is the C1971 book, by Dick Perry, “Not Just A Sound, The Story Of WLW” . You may still find that in libraries and used book stores. BTW, this is the station that tested at 500kW in the 1930's, so an interesting history, indeed.
